Make sure the pressure is 25 to 45 psi on the low side and that the pipes are getting cold on the low side.

Could be the vacuum controlled motors inside the dash.

Set climate control to hot then cold or the temperature control lever from hot to cold and listen for the vacuum motor operating the flap inside that changes the flow from the heater core to the evaporator inside the dash area.

Good luck to you.

Sounds like your compressor is getting too hot. Does it get cold when you are moving down the road? My Jimmy did the same thing and I live in Arizona where A/C is a must have and found the fan clutch was bad. Maybe worth looking into... Good luck.

My AC wasn't working so I thought I needed more freon but when I tried to fill it the gage was in the red. What's wrong with it?


On your gauge,is "red" high pressure or low pressure?
If you are seeing a high pressure on your low side connected gauge and the compressor is not running,that is a "full charge" or better stabilized in the system.If your compressor is not "kicking in" you may have a defective electrical component in the A/C system.With the engine running,you can jump 12v power the the compressor clutch momentarily just to see if it is working.Don't leave it jumped to long as the system is designed to cycle with pressure from the low side pressure switch which is the next place to check and the compressor can also be jumped at the low side switch.
If your "red" is low or no pressure,then you have a leak and repairs to the system to stop the leak will have to be made.You can add 134a at this time with the engine running and A/C requested,and as pressure rises in the A/C system,the compressor should "kick in" and cold air should start flowing in your dash vents.45 degrees at the dash vent airflow temp usually equals a full charge.
DO NOT add any aftermarket "134a" that shows an EXPLOSIVE label on it.These are not 134a and are usually butane and/or propane mixes that you MAY NOT want spraying on you in a collision/any situation where the A/C system has become ruptured/compromised.

2001 XL7 Airconditioning is not working only air not cold.


Is your compressor kicking on? If it is not kicking on chances are that either your compressor is bad, you have a bad switch, or a blown fuse. Another thing to look into is whether or not your A/C unit is fully charged with 134a coolant. If your unit is not fully charged it will not blow out cold air. I hope this helps you out.

The a/c will not cool, it will not take a charge. the clutch was kicking in and out until i release some of the system pressure. It will not engage and the system will not receive a charge.


I am assuming it has 134a. If you are trying to charge it yourself with those cheapie cans with the hose on them. They will charge but very slow, EXTREMELY slow sometimes essentally not charging the system. I am an SAE certified AC tech. I recomend getting a shop that is certified to charge it. If you want to try again. You now have too little of a charge to enguage the clutch. Yous should precharge what you can into the system. If you can charge it fast enough you can overide the pressure switch with a paper clip. The biger lines are the low side. The pressure switch is on the low side and usually on the passenger side. It will be the only electrical plug on the AC lines. Unplug it and jump the connection to enguage the clutch (2 wires). I do not recomend this to as you can severly damage the compressor if you do not get it charged fast enough. One more thing... always charge on the low side! Beware that 134a can cause sever freeze burns if anything ruptures or leaks on you. Only charge in a well ventilated area. CAUTION please. A shop will fix it and you may be wasting your 134a if you fail.

Air conditioner doesn't run.


it is the low pressure switch trying to save the compressor. the system is low on refrigant. on this ford it should be R-134a all new cars are that refrigant.

Air conditioning system is not colling the car ? what do Ineed to do ?


i need to know how is not cooling the car?
is the fan blowing air or is the blowing air not cold?
it probably isnt cold.lets try that.
put a set of 134a ac gauges on the system and verify pressures.if it has low freon you may hear the compressor turning on and off.if so for sure its low and you will just need to add freon.
go get a 134a fron fill kit not the conversion kit.
and begin to fill untill the comp stays on and air is blowing cold.then stop filling and enjoy.
do not over fill as this will cause it to not cool again.

I haver a 1989 cadi. and the air condi. compressor kicks on and offa and doesn't cool


if the compressor kicks on and off and doesn't cool this is the first sign of not having enough charge in the system. the a/c clutch will always kick on and off while running becuase this is dictated by the expansion valve which regulates the system, however you should have cool air about 50 degrees F for 134a at 35 psi on lowside and 130 150 psi on high side. the undercharge can becaused by degration of the 134a overtime or a leak in the system. have a certified ac tech look at the system and do a vaccum check for leaks if it holds a vaccum for 15 minutes at -29psi then there is no leak and the system just needs recharging.. please rate this

1995 buick skylark air condition problem


If the system is not fully charged the compressor will not run. Check to see it the system uses 134a refrigerant for the cooling system. You can buy them in Walmart or other parts stores and try to charge it yourself. It will tell you under the hood by the systems tag how much refrigerant it takes.

Air conditioning not cooling properly


It sure sounds like a restriction, but you seem to have covered most all the bases I would (I am a ASE Master technician) see if the fixed orifice is plugged or restricted??, maybe the system is freezing up, is the compressor cycling switch set correctly to approx 28-32 psi??
