The AC works, but just not well enough on a really hot day. On a day in the 90s I have to put it on Max AC and even then it does not cool down for a while and the air out of the vents is not ice cold.
So, it works, but I cannot tell if there is something wrong or not. I recently put in a can of AC Pro and it did not change anything.
2001 F150 5.4 4wd - AC not working but when I turn the temperature dial to the blue side and turn on the fan, super hot air comes out of the vents or wherever I direct the fan to blow (Floor, defrost, etc) I know it shouldn't blow ice cold especially since my AC doesn't work but.....shouldn't I feel a temp change coming from the vents when I move temp dial from the red area to the blue? It's max heat wherever I have it set.

Drove the truck on a trip the other day, about 650 miles with a loaded 5x8 trailer in tow. A/C started acting weird. When the truck was on level ground, or going down hill, the A/C was fine. Cold air coming out the correct dash vents. As soon as I started up hill, or put the truck under strain of acceleration, the A/C would stop blowing out the dash vents and would start coming out the floor or defrost vents, or just not come out anywhere.
When I turned the A/C off and just used the vent setting, it would do the same thing with the fresh air. I guessing this has something to do with my vacuum lines, somewhere. What I should be looking for and where?
The ac on my 97 chevy k1500 siverado works for about an hour then for no reason the air stops blowing thru the dash vents. The motor continues to run but will not blow thru the vents. At the same time my blower motor will slow down to the lower speed position even when I have it on high. But, if I shout off the ac for a view moments the air will start to come back up to speed and will begin to blow thru the dash vents again. I have replace all the blend doors excep the one for the cab recirculation. Replace the motor relay swith, the motor thermostat, and the dash mounted control module. The heater system seems to work fine.

View 30 RepliesMy A/C is blowing cold but only thru the defrost vents. First it was blowing normally from the dash but during acceleration or under load, the a/c would randomly blow from any vent, from the floor, dash, defrost. Now that stopped and it only blows from the defrost vents above the dash-board.
1997 F-150 XLT, 4.2 Liter, V6, manual transmission.
2003 F 150. 5.4 motor. 4x4. 270,000 miles. Climate control.
The A/C is ice cold.. For the first 12-15 miles, and then it shuts off and is warm.
I had it recharged at the shop just to be sure. When it works, it blows out the vent at approx. 42 degrees.. nice and cold.
This problem happens every time. Turning the climate control off and then back on doesn't work.
Shutting the truck off and then back on doesn't work. Wait a while.. Not quite sure how long, but the next time I drive it, it will work again. For about 12-15 miles and then blows warm again.
A bit of funky , moist smell to it when it blows warm.. Typical A/C smell I think.. The box could prob use a cleaning.
My digital odometer is funky! Sometimes time it works sometimes it doesn't. Sometimes it works on start up than after a lil while it fades out.
View 7 RepliesI was driving my f150 with the AC on, it has a 4 position fan switch. Lo, 1 , 2, and Hi. The fan only works on Hi. I don't think its a fuse, so what are the possibilities ?
View 3 RepliesSo my a/c works some times. I'll get in it in the morning, turn the a/c on. It works great, ice cold blowing hard. Then I'll turn the fan down from high and in a minute or so the cold air stops and it blows warm. Then for the rest of the day it wont blow cold air(i get in and out of my truck a dozen or so times through out the day turning the truck off each time). my dad has a freon pressure gauge. We checked it and it had good pressure. the blue gauge was at 50 and the red was a hundred and some i forget, but dad said "that's where it should be" so i guess that's not the problem. I am wondering if there is switch bad or a sensor. Its an '02 fx4 f150 4x4 140,000

View 9 RepliesI got a 2000 F250 XLT that the AC fan only works on high. Same thing in heat mode. Is there a relay for the other speeds that I need to check out?
View 2 Replies2002 f150 7700 with 5.4 triton and 4r100 tranny started chugging under acceleration and now stalls when put in D, 2 or 1. park and neutral are fine and reverse works perfectly.
Now when I put it in drive it chugs and stalls immediately... 1/10 times it will keep running but chug violently like its running out of gas. will get worse and stall if you press the gas. i can light the tires up for a block in reverse however.
Changed coils 1 2 and 3, IAC, bank 1 knock sensor, camshaft position sensor
My 2001 f150 super crew, the heat only works on speeds 1-3. All 4 speeds blow air fine, I'm talking about the temperature. not the blower. Could it be the heat resistor?
View 4 RepliesBought this truck earlier this year, and started to notice from time to time a smell in the cab that can only be described as propane. Truck was sound and the windows were down most of the time so I let it go. Probably not smart. With the windows up more often now, what this could be. It comes and goes. My guess is it's somehow coming through the vents, but what the heck is it? Is there anything in a truck that has mercaptan in it?

View 9 RepliesI'm guessing my heater core is bad as I smell coolant thru the vents. I think the blend door is broke too. I'm guessing the heater core and blend door are in the same area?
View 2 Repliesmy turn signals only work with the steering wheel tilted all the way up. It works for me, but my wife drives the truck mostly because we live a mile from her work. The dealer said it was a "peanut connector." And can someone walk me through the steps to fixing it?
View 8 RepliesI am having problems with the blower on my truck. I can feel the air coming from vents no matter what setting on it. I think it maybe the blower itself as it was working and just quit. Is there a fuse for the blower that I can check? And I have the V6 4.2L 2 wheel drive
View 8 RepliesAbout mid-October I noticed when it as real cold out and I had the heat running whenever I would come to a stop I noticed there is very little to no heat coming from the vents, despite the engine being warm and running at operating temps. At the time I was working for a shop and I asked one of the mechanics what the problem was. He said that it was the radiator not having enough coolant.
Turns out when we pulled the cap the coolant res, was just about bone dry. So we added in about a gallon or so of coolant with the truck running and sure enough at idle the heat was back.
Fast forward to the last couple of weeks and when I am sitting at idle again same thing happens. So somehow the engine is losing coolant. Its not ending up in the oil (no white on the dipstick) and there is not a coolant leak. As it sits there is 255,300 miles on the truck now. 1999 5.4L F150....
