My Air Conditioner in my 1994 GMC Sierra V6 Truck is blowing air that is not cold and on hot days it will blow hot. I was going to recharge the freon and i bought a can with a guage on it and the low pressure hose was reading 75 psi, which is too high of pressure to be putting in freon, so i took it to a service shop and they said one of the hoses was not connecting so it was not blowing cold air, they corrected it and now two days later my air conditioner is back to the same problem as before.

I have a 1994 buick lesabre. the car does not blow air or heat from the vents.. it only blows from the defrost vent. i also have the issue that the car only blows hot air when the ac is running.. i tried to add freon to the low pressure side.but did not hear the condenser turn on and no freon was sucked out of the can... if the vents do not work will this cause the condenser not to turn on?


The air circulation system is designed to go into default mode if it cannot function properly. Default mode is defrost only. That could also be why your getting heat only. The main reason that the system goes into default mode is a vacuum leak. Check ... 1994 Buick LeSabre

I have a 2007 dodge ram. If I turn the a/c on it blows hot. I figured the hot means low freon so I put a charge in it. Afterwards it blew cold but only at 1/2 volume and sounds like it should be blowing more air. I figure there's a vent stuck closed somewhere. I let the freon charge run its course and need a new charge again but would like it to blow harder like an a/c system should. Help

Two questions on my 1999 gmc suburban K1500: 1) The 4wd switch has no power (no lights lit) and will not switch. Its in 2WD now, but will not make any differential changes. Looking for troubleshooting suggestions? 2) The AC system blows really cold air for about an hour on interstate runs, but if you slow down for a few minutes it will start blowing hot air. If on interstate, I am guessing the heat keeps it from freezing up. I'm guessing its low on freon. Any other suggestions?

00 jetta ac not cooling, fans and a/c comp./clutch is working but no cool air.. unhooked the low side switch i think it is up top near the fire wall clutch kicks off on the a/c compressor so im guessing that switch is in working order.. a/c lines are not getting cool and blowing hot out of the vents, did blow freon out of the high and low sides of the line.. what could be the issue thx..


I would guess your freon has slowly leaked out, and now simply needs to be recharged. You can buy an AC recharge kit with R134 at Walmart or someplace, and do it yourself quite reasonably. If it doesn't cool after that the way everything else seems t ... 2000 Volkswagen Jetta TDI

The A/C is blowing hot air. The compressor comes on, the fan is turning for the A/C and a local Firestone put freon in saying it was low. The Firestone says the compressor or evaporator is bad. I have searched troubleshooting experts whom have told me that it is either the evaporator or a switch (?), not sure of name, could be bad. Because the compressor is coming on and the fan is turning and the unit blows air, hoping it is an inexpensive part. Could you advise, Thanks.


Could be pressure switch. When the guy put 134a in...find out what the pressure readings were on the suction line to find out if the compressor was working. May as well hook up the high side as well to get both readings. If there's a decent sepa ... BMW Z3

AC will blow cold air for a few minutes then start blowing hot air, cut the engine and start it again and blow cold air for a few minutes then start blowing hot air again. Just filled up the freon and the compressor deactivate about 5 minutes after blowing cold air.Low side is 40 psi, when deactivate goes over 80 psi. Hyundai 2002 2.7 liter, Santa Fe. Thought of pressure switch, dryer and expansion device. Any-one have any suggestion what it may be?


You have moisture in the system this causes your expancion valve to freeze up an stop working, thats why it works for sort time and when it de-freezes stars working again. you need to do a EVAC & RECHARGE with a good AC service equipment, specially ... 2002 Hyundai Santa Fe

I have a 2004 Sequoia and the heater continues to blow air when its turned off. If the temperature is set to cool before it is turned off, cooler air blows. If the temerature is set to hot before it is turned off, hot air continues to blow. Either way, the air blows at a low level. Any Ideas?

My air conditioning all of a sudden blows hot air especially on driver's side and when I turn off engine and restart (i.e., after I have been in grocery store) it will blow cold again for awhile before blowing hot again....what could be the problem? I know it is not a freon leak as that has been tested with the dye and the dealer replaced the a/c electronic control module and it blew hot air after only about 30 minutes. Any suggestions?


That sounds like there is a problem in the air direction chamber (for lack of a better word i cannot remember the true name). At first thought I would assume that the control switches were faulty but if that has been replaced maybe it is the valves a ... 2002 Ford Thunderbird

While car was idling, I heard a ''popping'' sound. Looked under hood, near the ac high pressure line there was a green leakage coming from the switch.The top had blown, possibly from the Tx heat.Ac now blows hot air, freon is still intact none has leaked. Could it be the high or low pressure switch that needs replacing?


Regardless the bad switch needs to be replaced. Your mostly going to loose some R134a and you may need to have the system serviced, but replacing the switch your self can be done like changing a spark plug. Just make sure yo ... 2003 Hyundai Accent

2002 jaguar s type 3.0L I started having problems two years ago with my heater not blowing hot air until i turned the thermostat to high then it would send the heat. Now recently since its been hot outside, I've been running the a/c on 72 and it started to blow hot air. I could turn it down to 67 and was cold again. Now it has to be on LOW to get cold air. Is it an actuator?.

Air Conditioner blows just hot air....A/c clutch not recycling as often after adding 24 ounces of refrigerant and still just hot air coming out vents. My thermometer in dash vent registers 160 degrees F. I've checked low side pressure to see if I overcharged the system, It is now reading 45 psi. The compressor clutch is not recycling at all now. Could this be a relay problem or something other than a low system? What about the A/C Cutout Relay? I don't want to pay by credit card


Lets do this step by step. 24 ounces is more that enough, and low pressure reads 45 now is this with clutch cycling cause if it is it high lets just say you in the yellow alert.OK. mercury marquis use a low pressure cycling switch.even if you have pr ... 1999 Mercury Grand Marquis

My a/c started blowing warm air. I went to the parts store and bought freon. I installed the freon to the correct pressure. The air was cold again. 2 days later it was blowing hot. I didn't hear the compressure go on. I decided to check and make sure the pressure was still ok. The minute I started to unscrew the cap the compresser stated up and now I have cold air again


Did you touch any wiring ??possibly a loose connection? a/c pump clutch???,anyway you wont be spending any money putting it right........good. ... 2003 Chevrolet Impala
