Ford A/C :: Hot Air Blowing / Clutch Does Not Engage But The Compressor Does Turn
Says A/C Compressor Clutch Circuit open. A/C blows hot air....go to VENT and the EATC controls the temp fine (ambient air only). It's on a '97 Lincoln Mark VIII if it makes any difference. Pulled code # 1530 ...
Clutch does not engage but the compressor does turn. Also the EATC will NOT go into the test mode. Push OFF and Floor at same time, then AUTO within two seconds. Nothing. Is this a clutch gap problem? New clutch was installed about a year ago.
Overheating - Nissan - Sentra - Heating :: Intermittent Heat / Blowing Cold Air
A few weeks ago my car started overheating and blowing cold air while I was on the highway. I took it to my mechanic and he found that the radiator was leaking. Two weeks later the car was overheating and the heater was blowing cold air when I was on the highway. I had it towed to the same mechanic and the car wouldn't overheat nor would it blow cold air. He drove it all around and on the highway but couldn't get the problems I was having to occur. Now I have intermittent heat. Sometimes I will start the car and it will take 20+ minutes for the heat to blow warm air. Other times the heat works fine for a while and then starts blowing cold air. Usually when it starts blowing cold air I begin to smell a sweet odor, possibly coolant. It hasn't overheated again, but I have stayed off the highway.
I just had the thermostat changed, and the upper radiator hose warms up quickly. When the heater is blowing cold air, one or both of the hoses connecting to the heater core do not warm up. Sometimes it's both hoses, other times the hose going in is hot but the other hose is cool. My mechanic seems to think that the head gasket is leaking air into the system, and that the air is preventing the coolant/water from being properly transported throughout the car. He did a pressure test to see if it was the head gasket when I brought the car in but it wasn't conclusive. Does it sound like a head gasket leak, or could it be a blocked heater core, or a weak water pump? So far I haven't noticed any coolant leaks, but I could be missing something.
Ford 6.0L Power Stroke Diesel :: Compressor Cycling But AC Not Blowing Cold At All
So my Ac is not blowing cold at all. I can hear the compressor cycling. I filled the sys with freon. Still not cold I am pretty sure I have a leak but wouldn't it still blow cold? What do I need to check to fix this? The temps are getting in the upper 90's and 100 s I need Ac bad...

I have a 2012 truck that the AC wasn't blowing cold air this summer so I took it in and they said nothing was wrong... Took back in and they replaced vent control... worked a little bit. Fall came and my windows fog up and really never clears up so I take it in and they said it is blowing hot air but I told them that isn't the problem but the moister in the cab is the problem. I feel I'm getting the run around.

This week was our first nice week of the year. Monday I got in my truck at lunch time turned the a.c. on and it blew ice cold. Today my truck sat in the sun all day and I got in it and turned the a.c. on. I noticed instead of the normal "click" you hear when the clutch engages in the a.c. compressor I got a wine and wimper kind of noise. The system never cooled the air after this happened. Is the compressor shot? Is it safe to drive or is the compressor going to tear itself up and send metal pieces thru the system?

I have a 2007 Saturn Relay minivan. The front heater blows hot but starts blowing cold when you stop even for a red light but will blow hot again when you speed up and the rear heater never does blow hot, what could cause this? This vehicle has about 93,000 miles on it.

The A/c stopped blowing cold on my 06 Passat 2.0t. I checked the pressures on the low side of the system and it was 100 psi with a cold engine and 130 when hot. Obviously this is too much. It seems as if the compressor is always engaged even when the a/c is off (every part of the a/c pulley is always spinning the little nut sticking out of the center of the pulley spins as well not but im not sure if that's how it is when the compressor isn't engaged).

View 2 RepliesGolf IV / Jetta IV :: 2002 - AC Quit Blowing Cold / Compressor Need To Be Charged?
The AC on my car (2002 Jetta 1.8t) quit blowing cold. Did some troubleshooting and...
1. Checked Freon- level was ok
2. Noticed cooling fans were not coming on with AC button pressed and ignition on. Fans also not coming on when car up to temperature, but gauge never went above normal. Seems strange considering I live in Houston and it was 95+ out.
3. tested fans with direct power and both high and low are fine.
4. jumped terminals 1,2 and 2,3 on plug for cooling fan switch and fans turn on high and low...so thought must be bad cooling fan switch.
5. Replaced cooling fan switch and still no fans or ac when AC button is pressed and ignition on.
6. replaced Fan control module. Still no fans.
7. Checked Freon once more...and although it was in the ok range decided to add a little more. (was in the middle of ok range, and a cheap gauge)
8. Compressor kicks on, along with cooling fan. End up using the 1 can I had and now have cold air and fans that come on when hitting the AC button with ignition set to on position.
I thought the mkiv cars would always turn on the fans when AC button is pressed with ignition on? Or does the compressor also need to be charged?
Lexus LS 2007+ :: 2008 600hl Heating System For Interior Not Working Properly When Extremely Cold Outside
Last spring i purchased an 08 600hl. This is my first winter with this car and I have come across an issue. when it is extremely cold like it has been for the past few days the heating system for the interior of the car does not seem to be working properly. when i warm up the car and put on the heat it blows cold air. It is only when I am driving that the heat comes on. While i am driving at a moderate speed the heat works fine. However, when i drive slow, such as driving around a parking lot and its only running on hybrid battery power, it starts to blow cold air again. When i put the car in park and its only running off the battery i only blows cold air even on the "HI" temperature. I have the rev the engine to get the heat to kick in and then it will stay on. This is and issue or a normal behavior for this car.

View 2 RepliesFord F-150 (2004-2008) :: AC Does Not Blow Cold At Times / Compressor Not Coming On
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.
Ford F-150 (2004-2008) :: Overheating / AC Quit Blowing Cold
Will the computer in a 2007 shut down the AC compressor in an overheating scenario because it would be considered non essential? Yesterday on my way home from work my AC quit blowing cold. I just had the compressor changed a couple of months ago so my first though was bad compressor. Then I noticed the temp gauge start to climb. The truck was over heating. There was a hole in the radiator. Now that the overheating problem is fixed the AC is again blowing cold. I just would like to know if I may be starting g to have issues with the compressor again or if it's natural for it to shut the compressor off because of overheating of the motor.

View 5 RepliesFord F-150 (2004-2008) :: A/C Not Blowing Cold Air / Clutch Not Engaging
Here is my problem: A/C not blowing cold air, blower motor working fine, checked all relevant fuses for A/C and R202 relay under the hood. Everything is fine here. Next, low pressure switch, jumped, clutch does not engage. Next removed relay R202 (clutch relay) measured voltages (at female sockets) where pins 1 and 3 would go, voltage OK. Jumped where pins 3 and 5 would go (bypass to see if clutch engages) and it does. Appears that the pressure switches check out OK (low pressure and A/C cycling switch - although this one not sure). CarMD unit was used as well, and no codes generated so perhaps PCM is working OK? I'm stumped, as a loss of GND by PCM or perhaps a corroded or open wire issue??
Also, possible the A/C switch on the HVAC control could be bad, but the light comes on, (doesn't mean switch is good necessarily). The rest of that unit works fine, control ***** that is, fan speed adjusts properly, air flow looks good. It appears this is an electrical problem where the clutch is not getting juice but I don't know the source of the problem. However, I also noticed that when the clutch/compressor was running (temporarily as described above) cold air still didn't come out. This, I assume, would mean I would need to add refrigerant or re-charge the A/C AFTER I get the clutch to engage electrically. 2004 F-150 5.4L ....
Ford F-150 (2004-2008) :: AC Blows Hot Air But Defrost Blowing Cold
My AC blows hot air, like heater hot, but the defrost on cold blows cold air. At first the AC would cut out at low rpm's (stop sign or red light) and cut back on, now its nothing. But the defrost blowing cold, enough to fog up the windshield, tells me its not the compressor or freon.

Every time my air compressor would shut off I got a loud annoying pop through the radio. Even if the radio was off I would still get the pop. I knew it couldn't be good for all the electronics in the truck so I tried a mod.
Diodes across the relay signal terminals need to be installed in performance carts to protect the electronics. I put one of these diodes on my truck this week. 100% of the pop is gone.

Ford A/C :: 2000 - Compressor Won't Always Engage Especially When Accelerating
I have a problem with my AC that is driving me mad. The compressor won't always engage, especially when accelerating. I browsed the forums and came upon this link; SpringerPop's Compressor Clutch Air Gap , very useful. With the AC on, when the compressor didn't engage, I just hit the clutch plate with a wood pole and the compressor immediately turned on.
So its definitely not pressure related and as far as I know, the relay and wiring are working or else it wouldn't even turn on. It works well for a few minutes (very well) and then it just stops working. Anyway, I read the instructions on that page. The thing is... when I put the keys in ON and turn the AC on... the clutch still doesn't engage, making it impossible for me to get the plate out to get the shim out.
