First warm week of the year now my 2014 is blowing hot air! I played with all the appropriate buttons. Air on, air off, tried voice commands and no luck. From what I have read is could be the pressure switch or the compressor. The compressor is definitely not engaging and at 17,500 miles I would think there was still freon in it. I have not done a system diagnosis yet..not sure how.
View 10 RepliesNot sure what happened with my Accent. When I turn on the A/C the blue lights come on, but the compressor is not kicking in and it's blowing warm air. I checked my fuses under the dash and in the engine bay and they look good.
View 10 RepliesGot in my truck this morning and everything worked fine, no problems. Arrived at my destination and parked. Come out about two hours later start the truck and my A/C wont blow air, My truck is an 05 lariat so it has the climate control A/C. Everything was working fine it just wont blow air, When i turned the A/C on and off i could hear/feel the small thump of the clutch engaging on the compressor. I am thinking the blower fan just went south? or maybe something stupid that controls the blower fan? Summer is in full swing here in central florida, temps are 95+ not including the humidity...
View 14 RepliesThe truck has been putting off a high squeal every time I crank the engine and when the A/C compressor is engaging.
My first idea was the accessory belt slipping on the compressor when its clutch kicked in. So I replaced the belt. The sound has dissipated a bit but is still there on initial start up and periodically while the A/C is on in the truck. If I turn the A/C button in the cab off the sound quits altogether.
My next idea is the A/C clutch. I prefer to work on my cars myself so if you can just replace the clutch without doing the whole compressor? The compressor works amazing and the truck gets ice cold in the TX heat so if I can keep it while just doing the clutch that would be amazing.
I noticed that if i'm turning my car on for the first time in a day (12-24 hours) on a hot day (80F + ) , the compressor on the AC doesn't kick on for about 3-4 minutes. It just blows out hot air for those first few minutes. Once it kicks on and i turn the car off and then on again some time during the day the compressor kicks on right away and cold air starts to blow normally.
My RX350 pumps out cold air almost asap, and so did my accord. My AC seems to have a musty smell if it hasn't been turned on in a few days either. it goes away as soon as air starts moving. How do I get rid of this permanently?
I have an 06 F350 diesel, I had some work done on it that required the body to be raised on it. After I got it back the A/C didn't blow cold. I put it off for a while since I didn't need it. Anyways, the clutch isn't engaging so the compressor doesn't spin.
Things I have checked: Compressor rotates smoothly by hand. No blown fuses or bad relays (checked them all with meter). No results when jumpering the Hi/low press switches. Tried charging the system and the gage I got with the can goes to 80# and it maxed out. For the air gap on the clutch/shim idea, I tried pushing in on the clutch while it was running with a long extension to see if I could get it to engage, no luck
Last year my a/c worked off and on. so far now its not working at all. Compressor isn't kicking on. i bought a bottle of the EZchill refrigerant to recharge the system. I took the relay out and added 12+ to the pin to kick on the compressor. Even with the compressor running the gauges are in the blue range which is the normal operating range. With the compressor running, the air is cold but when i stick the relay back in the compressor wont kick back on. I tested the relay and its fine. Also the compressor is rattling.
View 8 RepliesMy mother in law has a Santa Fe 2004 with a ~2.4. The AC compressor quit working over the winter. The AC compressor does not react to turning on the AC button.
I checked the fuses. I also tried changing out the AC relay with another one and it still didn't respond. The relay also didn't sound as though it was clicking over. The AC indiacator light is working.
Could it be the actual button has failed or is there a way to check if the button is functioning?
How does the compressor know to engage? Is there a place I can test 12v at the compressor?
So I have a 2005 gli here is what's going on. The ac compressor is not engaging, the reticulation button is not lighting up when pressed in, the cruise control is not coming on and the daytime running lights are not turning off when the hand brake is engaged. And the radiator cooling fans to not spin when the engine is first started. I have checked all the fuses inside and over the battery. I have checked the relays ( they click when hooked up to power). I'm suspecting a bad fan control module. I've done some searching and that's the only thing I have found that would control the fans and the ac.
View 2 Replies129k miles, first time ever noticed a/c compressor not engaging -- hadn't tried a/c in a few months, winter and all... Jumpered the cycle switch and determined it was low pressure situation -- took to dealer, who recharged/diagnosed leak situation. Compressor oil leak at front seal (needs replacement) and refrigerant leak at manifold hose assembly.
However - compressor running nice and quiet, after recharge, no problems, silent operation. Couple questions:
1. Ford manual says no need to replace accumulator unless there is evidence of compressor failure (which mine hasn't yet) -- is that 'evidence' trash in the orifice tube? If so, where precisely is it? I know it's in one of the tube assemblies, but can't visualize the location from the diagrams.
2. Since my compressor hadn't failed, still running quiet/smooth, can I just replace that and the leaky hose assembly and be done w/it?
3. Is this a job that's beyond the moderately skilled garage mechanic? I handle most of my own jobs with exception of heavy engine (i.e., heads, etc) but have never attempted a/c-related due to the refrigerant portion of this job. I'm sure I can obtain the proper vacuum equipment somehow, if it's something that's not too overly complicated...
I have a 1991 Bonne LE with 150,000 miles. Have had GREAT luck with this car but realize it is getting high miles. I recently drove it about 250 mile trip and the A/C worked perfectly staying nice and cold. The next time I drove it, when I turned the A/C on, it got cold after about 5-10 seconds and then it was like you turned only the blower on with no A/C. It does the same thing every time I turn the A/C on, gets cold fast, then just neutral temp with no cold air.
I checked the compressor switch and it is working fine, and the compressor is engaging and staying engaged, but not outputting cold air except for the first 10 seconds or so. I do believe the temperature door inside the dash is opening properly. What I might check myself before taking the car in for A/C service? I am capable of replacing the compressor & seals myself but would have to have someone discharge the system and then recharge it afterwards.
The car is a rebuilder that I bought about 10 years ago. The fellow (very trustworthy) who rebuilt it replaced all the A/C o-ring seals when I bought it and made sure the system was fully charged. It has worked perfectly this whole time. He also gave me the a/c compressor and other parts from the parts car that was used to rebuild this one.
2002 1500 4WD 126K miles. A/C not working, compressor does not engage when A/C is switched on. Is there an interlock if the refrigerant level is too low to keep the compressor from engaging? Original owner, A/C has never been recharged. Is recharging my best first step.
View 2 RepliesAC stop working after an alternator replacement ?. I tried crawling under the truck to see if the mechanic didn't plug the compressor back in as he said he had to take it off to get the Alt out, but it looks like the plug is fine. Would the refrigerant have leak all out when he took it off ?. Should I try to re - charge myself with Red - tek kit from Canadian tire ?. The compressor will spin easy enough when I reach down and move it by hand but will not engage when I press in the AC buttons.
View 4 Repliesl have a 2000 model accent and the air conditioner compressor clutch is not engaging . you press the 'AC 'button and the indicator comes on when a fan speed is selected which l am sure is the correct operation.l checked for 12 volts at the coil terminals of the relay and there is no 12 volts.l shorted the switch contacts of AC relay and the compressor did engage so the wiring from the relay base to the the compressor clutch is ok. l also checked the contacts of the 'AC' switch itself and it seems to be ok. l haven't had much luck with sorting out the wiring from the switch to the relay as l do not have a wiring diagram.
View 4 RepliesHave an issue with my front air con not working.....
When you start the car there is a rattle/squeaking noise, this sounds like a worn pulley, when you press the air con button to turn it on the noise stops. It does not make any sound changes to the unit/engine to indicate the compressor engages and the is no cooling from the unit.....
Is it a new compressor or is there a common fix for this issue?
I have a 2001 ranger 4x4 4.0 L with what appears to be a unique a/c problem. Over the last week the compressor will not kick on immediately and seems to randomly decide when it is going to function. Once it starts, it runs properly and cools well, until I turn the engine off and it is back to square one. We have checked the coolant level and it is full. the problem seems to be getting progressively worse....At first it took about 15 minutes for it to decide to trip, then 30 minutes, and yesterday I drove for over an hour and the compressor never kicked on.
View 4 Replies2012 6.2 XLT 50,000 miles with manual single zone controls. I haven't had time to work on it yet, but it seems that my AC compressor is not engaging. The dash controls light up normal, fan comes on, etc. I am just looking to see if there are any common failure points. I know it COULD be low on charge, clutch could be bad, etc. I am just checking if there is a common failure with these trucks AC system.
View 10 Repliessoo a friends 03 f-150 w/ the 4.6 has noticed the a/c compressor clutch engaging while heater is on. clutch engages for about 3 seconds or so and kicks back out consistently but only w/ the heater on. a/c dose function property when using a/c functions... Is this normal or does something need serviced???
View 3 RepliesI recently purchased a 2005 Monte Carlo, it has the 3.4l V6. I live in Pa. and like others our winter has been real cold, I was waiting to pick up my wife from work the other day, while sitting in the car i was changing the heat selections from defrost to floor to bi-level and realized that the A/C compressor clutch is engaging when the selector is on defrost and floor, it disengages on bi-level. I know that it is supposed to engage on defrost. Is it normal for this car to activate the A/C on floor? if so it is a first for me.
View 4 RepliesI have a 2000 chevy malibu that has not had a/c the past 2 summers. I'm trying to diagnose what the problem could be. When I start the car and then turn on the a/c by pressing the button in the car nothing seems to happen.
When I went to look at the compressor motor I could see that the clutch is not engage and the middle of the compressor is not turning. What to check without taking to a mechanic??
Ok here is the issue, my girlfriend owns a MK4 '99 Jetta. Through the search I was able to figure out why she is having so many issues with her door locks and how they can be fixed on the cheap..thats awesome. But here is the problem. She was driving down the road the other day, A/C working...then suddenly it stopped blowing cold. Fan is still working, just blows hot air. She said it started blowing warm suddenly and hasnt been getting warmer through out the past days or anything.
With the hood popped and the a/c on, you can see that the compressor isnt engaging. The car makes a noise like its engaging the compressor, but nothing is happening that I can see visually. Seems as if the compressor is not getting the signal to engage. It sounds like its trying to make the compressor kick on about every 5 seconds or so. Basically that initial clicking sound that your hear RIGHT before the compressor comes on when its working normally.
We have checked the fuses and no luck with those, all look good. Seems like its an electrical issue to me. What this may be? Bad pressure switch? Low pressure in the system? I know the car has had the compressor replaced before...and the clutch seems to spin freely when the car is off.
