Prius (2004-09) :: AC Compressor And Condenser Cooling Fan Will Not Come On
Dec 21, 2011
I have an 05 Prius with 53k miles and the ac just recently stopped working. The blower fan still comes on, but neither the compressor nor condenser cooling fan will come on. I've checked the fuses and relays, and they check out ok. I'm hoping there may be one I missed? It just stopped working with no warning signs. What could be causing this? If the compressor was bad, the condenser fan would still work, right? I'm fearing it's the ac inverter. Do the symptoms match?

I think i have a truck with a condenser that has a restriction, how i could prove this with a test or something maybe like a temp test across from the inlet to outlet side...the symptoms are lack of cooling the hotter the temp outside the worse the cooling is also when it rains while I am driving the it fezzes me out....ill post pressure readings later.

I noticed my A/C hasn't been up to par. It's not bad when driving but just ok when idling. So today I changed the orfice tube and the accumulator. Vacuumed the sys. down and charged it up, 2 lbs 10 oz. It is worse! the compressor kicks on and off constantly only cooling to 80 degrees.
I noticed the high goes right up to 350 then the compressor shuts off .... 7 seconds later, back on and up to 350lbs and off again. I think the high-pressure switch is shutting the compressor off before anything goes kaboom but why isn't my fan cooling the condenser down? my FSS shows no increase in fan speed. Sitting at 450.
I think I'm going to cool the condenser down with a hose now to see if that works. If so, That would be telling me the fan isn't doing it's job correct?

I have been told my AC hose from the Compressor to the Condenser is leaking. How much time do I have to get repaired before AC stops cooling. Can I just get the hose replaced and about how much should it cost? This is a 2000 model.

My 6.0 is cooling poorly . Clutch is engaging , condenser free of obstructions, static charge L95 , H. 105. Running psi at 94 ambient is 50 and 225. This morning with cooler ambient in mid 70's it was 40 and 200. I'm thinking compressor .

So the A/C on my wife's 2013 Tiguan stopped working suddenly this past Thursday, just our luck this weekend was the start of a 95+ degree week. Took it to the dealership today for a diagnostic and they came back saying that the line between the condenser and compressor has a leak and needs to be replaced. They're estimating about $690 including tax for the job, this includes the AC evac and refill.

1994 geo tracker... I'm trying to get my A/C working, but I'm running into an electrical issue somewhere. The relays for the condenser fan and compressor are not activating, even though they are getting 12V when I switch on the A/C. I can run a jumper across where the relay would switch and both turn on and my A/C is cold, but it won't do it without the jumper. I've traced back from my battery to the A/C and checked my dual pressure switch, I'm slowly trying to pick out wires which may have fried.
Both relays work when connected to the battery alone. If I jump the 12V and ground on the harness for the compressor and the harness for the condenser fan, they kick on and A/C is cold. Fuses are good, dual pressure switch is good? It's almost like the relays aren't getting enough current to activate, one of them the switching signal reads only 4 V which is too low, that's for the fan. The compressor reads 12V though on the switch. When back probing them with the relay connected I only read 0.25 V, I don't know if that matters or not.

My daughter has a 02 stang with the 3.8 . the other day she complained that her ac was not cooling so i put my gauges on it and checked the freon. the compressor was on and the low side showed about 35 and high side was about 225. it was cooling good, now today it was not cooling at all and the compressor was not on so i jumped the pressure switch on the dryer and it came on, pulled the jumper and plugged it back in and compressor came back on and started cooling. I might have a bad pressure switch also about the pressures could the orfice tube be getting stopped up. this car must have had ac problems before with the previous owner because someone has wired the ac clutch 12v+ wire to the outlet side of the pressure switch and the 12v- side to a ground screw.

03 Santa Fe, 2.7 L engine. No cooling happening. Compressor not running. Jumpered both sides of the triple pressure switch. Jumpering Low/high side resulted in slight increase in engine rpm, Jumpering medium side and something turned on (didn't get a chance to investigate) but still no clutch operation on compressor. Wondering what to try next other than disconnecting and dropping compressor ?? Checked AC relay on the bench and the coil operates and contacts close, so that's good. Also10A fuse before relay contacts is OK.

We have a 2003 Nissan frontier pickup (automatic).The AC recently stopped cooling, but the fan works. It was cooling perfectly great when all of a sudden, it stopped. If we turn the AC on, the compressor (I'm guessing) starts to click and continues to click until turned off. (started to grind under hood). It's not a rattle, definitely a click as if it wants to turn on but can't make the electrical connection. It kind of sounds like when a starter has gone bad and it clicks. Except, it does it repetitively until turned off. This doesn't happen if we turn on the fan but leave the AC off. Does it sound like the compressor went out? How can we troubleshoot it?

I have a 98 Grand am with the 2.5 and recently noticed first that the a/c compressor wasn't coming on. It had freon added recently and did okay for a few days,then no compressor coming on again. (It still has freon) Then I noticed that the engine cooling fan was running as long as the engine is running on cold or hot engine with heat controls off (I know the compressor runs when on on defrost position as well as a/c). I thought the 2 problems may be related? I found 5 relays at R/F strut tower and the 3rd relay cut off the fan,so I swapped some of the relays, but made no difference.The fan only quits when I turn the engine off, and I can't get the a/c compressor to come. I don't if I have 2 seperate problems or not. Could it be the PCM?

The issue I'm having is the A/C. When I got the truck the A/C was completely freezing. Recently however, the compressor was having issues not engaging and I fixed that by simply plugging the cord to the accumulator thing. . Now the compressor engages, but is not cooling really at all. It is an old truck and the compressor is a little worn from what I see maybe 2mm space when not engaged. I checked the levels of freon/coolant with a gauge and the amount is perfectly fine. Plus there seems to be no leaks.

2007 Ford F150 half-ton. No cooling of air at the outlet of the ductwork. Freon charge is good, I watched the tech pull the system down and hold it for the prescribed time period. Compressor will not start. I am being told that this means a failed compressor, but I am of the idea that the pressure switch for low pressure must have failed, or the orifice is stopped up. I am also being told that the compressor, evaporator, and orifice tube needs replaced in order to remedy this issue. The counter man at my local parts house cannot find in his computer any pressure switches, kinda making me think that everything is in the unit. In short, if I can avoid buying the compressor, I would like to.

Have 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?

Other than lack of cooling ,will a failed ac compressor on a 2006 Volkswagen Beetle cause other issues if not repaired? it is a convertible.

Cooling Fans and a/c compressor not working-2000 Grand Prix. They both work when I jumper them. Replaced coolant temperature sensor, checked fuses and relays -all good. Not sure what to troubleshoot from here.

99 lumina. Ac was not working. I added a few oz's and the compressor clicked on but cooling fans were not running. After 10 min of idling the fans did come on but went off after 1-2 minutes. It seemed like they were responding to coolant temp more than ac pressure. Do the fans run when the hi pressure rises to a certain point where the computer will turn on fans?

My prius 2004 AC not cool what really problem come from ? I didn't do anything with it....

My air-con has packed up and I have been quoted nearly a thousand pounds to fix it. The problem is a leak in the condenser, which needs to be replaced. I've tried to source one myself, but there is some confusion over whether or not the condenser and the coolant radiators are combined, there is a vast difference in online prices.

Here is the issue i am having. 2011 F-350 King ranch with all bells and whistles. In Arizona now we are in the season that the weather is cold in the AM and sometimes hot enough in the late afternoon to need the A/C in the truck. with the settings on Auto which i normally do, and the external temp reading in the 80s, and the internal thermostat set at 70 or lower, the A/C compressor will not engage and allow for cooling the cab of the truck. But sometimes it will work just fine. I am assuming there is a temp sensor for cabin temperature. Where that is located. or will i have to change out the entire Climate Control Module. I would take it in to have it checked out but it is an intermittent problem, and i cant not have my truck for a couple of days while they try and figure it out.

I have 05 prius and the cooling fans wont kick on as well as the ac wont work. I have had the cooling fan motors checked they are good. I have changed the 2 cooling fans relays and the cooling fans still wont kick on.
When I bought the car the check engine light was on so I had it scanned and it threw the code P1121 coolant valve control. so I went and bought this part since I heard it was a common problem but haven't got it put on yet. Could this cause the cooling fans to not kick on and ac not to work or is it something else?
