Ford F-150 (2004-2008) :: AC Does Not Blow Cold At Times / Compressor Not Coming On
Jan 26, 2014
I have a 2007 F150 with a 5.4. I am having an issue with my A/C and more.
Here are the symptoms:
1) A/C doesn't blow cold, at times.
2) Compressor not coming on, according to mechanic.
3) Engine sounds like a freight train, at times. Like on a super cold day and it has to work hard.
4) Very poor fuel mileage since this started.
I took it to a shop, and they said it was the engine cooling fan that would not come on. So I replaced it. Same issue. I then took it back and was told there is a wiring problem. After 3 days they couldn't find it. I needed my truck back and dropped it off again. Then they said it was the A/C compressor, maybe. They wanted to try it and then see what happened. I told them no way.
Temperature, according to the gauge is good. Noise comes and goes. Not dependent on anything. Weather, temperature, car heated up or dead cold. Just comes and goes.

Noticed a small whine coming from the A/C compressor? I caught ear of it the other morning when I was putting the trash on the street and the truck was running. It's definitely the A/C because when you cut it off the noise goes away.

I have a 98 Buick Regal. When my air conditioning works, it is beautiful. On a hot and sunny day when I pull out of the garage, I can run the air conditioning until the car is turned off. After reaching a destination and parking in the hot sun the compressor will not blow cold air. If the day is overcast or cool, the air conditioning works fine. What the problem might be?

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.

The A/C does not blow cold. The Compressor clutch does kick on and stay on The passenger side fan kicks on only (I think the driver side is toast but i need to test it to confirm) The system has 45psi on the low side
I did not check the high side as I don't have a gauge for it but will get one if I need to test that. So my thoughts are that my expansion valve is toast which is what expands the hot liquid and turns it to cool liquid so the A/C gets cold. I think this because it seems all of the other components work.

I'm at the end of my rope! My 2005 Ford Five Hundred Limited has a constant problem with the A/C system and overheating. In the last year I've replaced the compress, expansion valve, dryer FOUR times. They have replaced the condenser, blower motor, and added Freon, and checked for leaks. It will blow cold when running fast and then blow hot. They have replaced belts pulleys, They have replaced the thermostat, fans, coolant reservoir, hoses. and it still overheats. I've taken it to 4 difference mechanics including two dealerships. No one can seem to fix this problem.

My 2005 Prius is having a problem with the AC. It will only blow cold air if the temp is set at MAX COLD. Any other temp setting and it will blow hot air. Really hot air. It makes no difference what the outside or inside temps are. Is there a simple fix for this? I can control the AC by setting it on Max Cold and changing the fan speed, but I would like for it to work on the auto setting the way it is supposed to.

When I turn on my air conditioner it just blows air, not cold air just air. If I turn it to heat it also just blows air, not warm air, just air. The fan settings all work fine but the air coming out never changes temperature. By the way, If I bypass the compressor clutch relay with a paper clip, the AC will kick in. I refilled the coolant in the AC system too but it won't engage without bypassing the relay. Plus, the heater is not "kicking in" either. I did recently install a new wiper motor but I am not sure if that may have contributed to the air issue that is happening now.

Push A/C button is always on green. The (air speed) 01234 button is also always on green. the Push button turns on and off orange whenever I click it.
Anyways, the AC doesn't blow any hot air... always just cold. I've adjusted the dial to red and have left it there for a long time... no hot air. Any trouble shooting I can do?

I thought blend door only adjusted temperature. Mine is manual? System no ECM control. Need defrost....

So, my A/C in the 2005 doesn't blow cold. It blows, just not cold.
The dealer recommended doing an evac/recharge, which, from what i understand, is there way of finding out where I have a leak.
I took it to my local shop, since the dealer wanted a lot of cash to do this. After having my car in their lot all day, the local fellows called me to say that they couldn't do any recharging/service on my A/C since the coolant is something only the dealer can get (which is a special kind of coolant with special lube in it, right?).

My 2007 Prius does not blow cold air, I bought the car back in March, when the weather was cold, so I never used the AC. I don't use the AC at all, I always roll my windows down if it ever gets too hot, but I recently have guests over, and I turned the AC on as I thought it would be a better and comfortable drive for my guests who are in town.
Anywho, the AC doesn't work. I obviously feel air, and I feel the apropriate levels (low, medium, high), but the temperature is just warm. It is set all the way to the lowest. I was going to fill up the refrigerant, but after doing some research, I quickly stopped and saw that the Prius has a very complex approach to its AC system. I am not sure if this is really a compressor issue, or just having low levels of refrigerant, but I'd love to get down to a basic diagnosis so I can understand what my costs are, and what potential issues it can cause.

I have owned my 2008 Rx 400 h for just over two months now and at the risk of sounding dense, am I right in assuming that when you are coasting along without the engine running, the heater will start to blow cold air? Everything works fine until you lift your foot off the pedal. This is my first Lexus/Toyota and hybrid so I'm not totally au fait with how it should be working.

I have a 2008 Ford Lariat F150 with 53k miles. The transmission seems like it slips at times. Here's the scenario. When I take off from a standstill and going through the gears at a normal acceleration pace, say I momentarily lighten the acceleration pace then try to resume. At that point, the transmission seems to slip momentarily, then bumps back into the pull mode. It feels like there is slack in the drivetrain until it re-engages, or like the lockup torque converter momentarily releases until the computer has time to react to the accelerator positioner calling for more. One guy said the transmission is, at that point, between two gears... either trying to decide to downshift or to upshift, but you can feel the surge in rpm momentarily until it decides ... then bump and your off and running again. If I push the O/D button, it stops doing it. What I can do? Because the dealer can't seem to get it to act up when they test drive it. It does it fairly regularly on me though.

For the last little while I have been having an issue with the 4wd in my 2006 F-150 with about 93k on the clock. Sometimes it would engage when I switched to 4H/4L and other times it wouldn't. A friend of mine works at a Ford dealership and said it could be the vacuum solenoid on the firewall going bad. So I bought a new one and as I removed the old one, noticed debris in one of the inlets. So I cleaned that out and neither old or new solved the problem. Then I went through ALL of the vacuum lines and found some debris in parts of them....
Cleaned them all out and still nothing. Then I got to thinking it may be the ESOF motor on the transfer case. Checked to make sure there was power to the plug, which there was. Removed the motor and turned switch, and the motor seemed to be working. Reattached the motor and the 4wd would engage/disengage without problem. Pretty much everywhere I went I would check it and it worked fine . Then all of a sudden it didn't . So I took the motor off, turned selector and it worked fine. No issues yesterday at all.
So, I am not sure if it is the motor going bad or not. Could there be a contact problem? I talked to a mechanic this morning and he told me to drive around with it in 4H for a while because more times than not it doesn't get used enough. I'm just not sure what could be going on...am I missing something?

I have 2006 single cab stx and the little orange airbag guy below the speedometer has been on over a year and a half and he always flashes a code 51, but I've never worried about it.
About a month ago I started occasionally getting the 5 beeps 5 times, and now it does it more frequently but not every time. The Passenger Airbag Light above the radio works properly. It comes on when I start the truck and then goes off. When I put weight on the seat (usually my Jack Russell who only weighs 14lbs) it turns on and stays, and if the seat belt is buckled with no weight it also stays on. This is proper function correct ?
I've tried things I've read from replacing or cleaning up the crash sensor in front of the radiator, even cleaned the connections under the seats with contact cleaner, pulled fuses and none of them are blown. Are the code 51 and the beeping alarm somehow connected ?

So our 2006 f150 fx4 has been having an issue with stiff steering... at times like it doesn't have power steering at all.
We recently had the lower ball joints on both sides replaced. Before that the upper control arm on the drivers side was also replaced.
There are days that it is better... other times not so much.

3 months ago.. I had my fan clutch replaced, along with alternator.. a few coils.. a belt and an oil change. While installing fan clutch the shop accidentally poked a hole in radiator so they got a new one ( After Market) and replaced it. After leaving the shop, I noticed the fan clutch was not rotating smoothly, it had a considerable wobble to it, so took it back and it was replaced..new one did same things.. so it was replaced again. Truck seemed fine after the 3rd one was installed, and then after a a 3 hour drive.. i pulled over to gas station, and while truck was at idle in park.. it started to run hot. Raised hood, there was no visible coolant in holding tank on side, so after a while.. i took cap off and as I released it... coolant started to bubble back into holding tank. I then started truck up.. it was fine rest of way home.
Over next few weeks, this happened 4 times.. ac will be on, truck sitting still at red light etc.. and truck will start to run hot. So i had a new thermostat installed, and also a new water pump. Took it to a guy who runs a shop i know and also had system vacuumed. ( it was burped prior). Thought we had it fixed.. NOPE.. did it again yesterday. So truck has had new fan clutch, new thermostat, new water pump, new coolant, new radiator.. and it still only runs hot if at idle.. and it wont do it all the time.. but about once a week.. it will... and it will go over to red.. and ill shut it off and after about 10 min.. turn back on and continue on my way.. What I noticed..and this may be a key piece of info to someone who may know what is going on... it seems that the times it has ran hot.. while at idle the fan clutch was off.. and once i reved engine up to 2500-3000 rpms.. I got clutch to engage and bam !!.. truck comes back down to normal temp.. midway on gauge .. AS long as I am driving down road.. no problems.
** Also as a sidenote.. my engine does have a engine coolant temp sensor on it. Part # DY 1025 motorcraft. On some vehicles.. this part tells the fan when to turn on.. not sure if it does on mine. Originally , I took truck in bc fan clutch was staying engaged to much..meaning fan was on all the time. So.. maybe it could be the sensor ?... now all the new fan clutchs that have been put on do not come on like they are suppose to.. work right sometimes.. other times.. truck has to be at high rpms to get it to engage.. not working right all the time at low rpms.
Are their fan clutch relays ?.. I have an electric fan clutch.. This seems to me that this is a fan clutch issue.. and this is the 3rd one on the truck.. came from autozone.. it is the correct one for truck and has a warranty. Mechanic now wants to try going with a ford fan clutch by motorcraft.. 2007 F150 5.4 V8 ...
