Ford Excursion :: 2005 - AC Quit Blowing Cold
My 05 has always had good air conditioning front and back but around three weeks ago it quit blowing cold. I found all the 134 had leaked out through a pin hole in the aluminum line that runs down the back of the engine to the rear ac unit. I removed the line and brazed the pin hole. So I reinstalled the line, put a vacume on the system for 20 mins then let it sit for another 20 to make sure I had no leaks. All seemed good so I re charged the system. Now my front blows nice and cold but the rear is warm?
My pressures at idle are around 40psi low side and 200ish on the high side when the engine is warmed up and the ambeint temp is around 74 f. If I turn it to the warmest setting for the rear it gets noticeably hotter so I'm thinking the blend door is working properly?? I've read that the thermal expansion valves can give some trouble so I pulled the jack and cubby out to gain access to it. I tried tapping on it with no gains. Also the top left line seems to be pretty cold coming out of it too the evaporator but the line coming out of the evap is room temp. I was very careful not to let any junk get into the lines when they were apart for the line repair but I'm thinking maybe some junk has plugged up the TXV?
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.

I'm having the same issue as many others with the heat blowing cold air. I have read through the other post ad tried the blend door, actutator, vaccine lines, control ***, and both lines going in and out are hot to touch when warmed up. I am now lost!

99 f250 4x4 7.3 superduty has no heat. A/c seems to work ok had similar problem last year and replaced heat control switch in dash. Same thing this year, a/c works fine but no heat when turned to red or heat setting. Blower works fine just blows cold air. What may be sticking? Getting cold in MD and (excuse me but) Johnson goes full turtle on my morning ride to work.

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.

I have a 2002 f150 supercrew 5.4 liter. About mid winter my heat suddenly went from hot to lukewarm. A check of the fluids shows all is good. I use my truck solely for work so I didn't bother with it at the time. Summer is here and my AC blows kinda cold, at best. I can hear the blend door moving. The temp control does make a huge difference. It just doesn't get real cold or real hot. Not like it should.

I currently own a 2003 Hyundai Santa Fe with 135,000K miles on it, and have had continual problems with the A/C not blowing cold over the last year or so.
A year ago, took it to what I thought was a reputable mechanic (not a dealer) who diagnosed the problem as a "bad" master circuit board. Thing ran fine for about 6 months, then started to intermittently blow warm air, until it finally quit blowing cold.
Finally broke down and took it to the dealer hoping they would be able to fix the problem. They charged me $110 and told me the refrigerant was low so they topped it off. 6 weeks later, once again not blowing cold, took it back. They said this time they found a "leak" in the refrigerant hose, replaced the hose, topped off the refrigerant, and sent me on my way (free of charge, of course, since they should have fixed it the first time).
Well...6 weeks later and once again, not blowing cold, so back to the dealer I go. Once again, they said the hose was "leaking" and they did the dye test (shouldn't they have done this the first time?) and replaced the hose, and the refrigerant. Good for another 6 weeks, then once again, not blowing cold.

It was blowing cold and stopped. Minutes later it started again and then stopped. This went on for a week and then stopped altogether. Car has 190,000 miles. Is it compressor, clutch or relay....
View 5 RepliesPassat (B5) :: 2003 V6 AC Blows Hard But Quit Blowing Cold
Have 2003 V6 FWD Passat. A/C blows hard but quit blowing cold. Noticed last week, that sitting for a long light, A/C would quit blowing cold, then cycle on again every 20-30 sec. After worked fine. Yesterday no cold air.
Read on forums about the 384 relay. My electric fan is NOT coming on. Started car, turned A/C on high, and checked voltage on connecter to fan. was negligible. Car was fully warmed up, so i figure voltage should be 14.0 VDC
Making assumption that it is either the AC relay 384, or the fan relay but there are two, a 214 and a 213.
Volvo :: Car Is Blowing Cold Air But No Heat At All
My car is blowing cold air but no heat at all. I checked the codes and it's throwing a B1 1-3-1. It's also throwing a A7 1-2-2. a buddy of mine is a mechanic but not too familiar with Volvo's. But he said that he thinks the B1 1-3-1 Driver's side air duct short is the problem. Is this the problem and how do I fix it?
View 3 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?
Ford F-150 - 1997-2003 :: Heat Started Blowing Cold / Temp Gauge Showing Lower Then Overheated
Was driving my truck I have a 97 f150 4x4 4.6L, btw. The heater started blowing cold air and I looked at the temp gauge but it was showing lower than it normally does and then, after a couple of miles or so I looked at the temp gauge again. By this time I was in my driveway. And it was overheating it might have been that way before I looked at the temp gauge again. But any way I opened the hood didn't see any leaks, all my hoses were hot except the top heater hose. Also checked the oil it was full and coolant was too, what this could be? Sounds like a t-stat to me? But could be worse. Also forgot to mention that the oil had no signs of water in there nor the expansion tank cap !

I have an 06 Prius. I was driving my Prius today and I've noticed that my car has NO HOT AIR...
And this is Winter!! I was driving for about 20 mins and still...No Hot air...vents are blowing cold (cool) air.
I recently changed my condenser/radiator but I did NOT fill my condensor with the A/C gas yet. (could that be the problem?) But isn't the gas inside condenser is for A/C and not for the Hot air??
Any other stuff that I need to check to solve this problem?? (harness, fuse etc.?) It's cold outside and my car has NO HEAT!
Caravan/Voyager :: 1996 - Heat Just Blowing Cold Air Out
1996 Plymouth Voyager ... My Van has about 90,000 miles and runs good. The heat worked great last year but is just blowing cold air out this year. I do not know where to start looking for the problem. I do not have a over-heating problem and it blows air out just as strong as before this problem. I had to replace the battery last month, could that have anything to do with this problem?

I have just cold air blowing at idle and under load. I have read posts and checked the following: temp remains at 190, heater coil hoses-both are hot and removed the dash to see if the flapper door (red arm) was moving-it is. Any other things I can check?
Honda - Accord :: 2004 - No Hot Or Cold Air Blowing From Vents With Heat Or AC
Nothing will blow out from vents, with heat or AC. I checked the fuse under the hood and that had continuity, I checked the 7.5 fuse under the dash and that was fine. I also replaced the blower motor resistor and the blower motor with brand new ones. Also used a test light to make sure power was getting to the resistor and motor and that is all good.

Camry :: Heat Only On Driver Side / Cold Air Blowing In The Rest Of The Car
I have an 2004 Camry XLE which just had the coolant flushed. Now I only have heat on the driver side. It blows cold air in the rest of the car. Temperature runs normal. Antifreeze is full. I can get more heat if I recirculate from the inside rather than bring in air from outside. It is zero in NY. Car never heats up on HOT!
View 2 RepliesPassat - Volkswagen :: 2002 - Only Cold Air Blowing When It Is Supposed To Be Heat
I have a 2002 Passat that is only blowing cold air when it is supposed to be heat. I have checked the following items:
1. Both heater hoses are hot at the heater core which would indicate that the core is not restricted.
2. Air has been bled at the heater core and the antifreeze is at the correct level.
3. Car thermostat is operating correctly and maintains a steady 190 to 195 degrees.
4. When temperature control lever is moved from "cold" to "hot" the air noise definitely changes like a damper is moving but there is no change in air temperature. This is a manual control with cables (not digital read-out).
From what I have read so far I am convinced that there is a problem with the blend door but referring you back to #4 (air noise change) I believe that the cable is moving the damper. Can the blend door be accessed on this car without removing the center console? Can it be accessed through the glove box area?
