    ok also the radiator cooling fans dont come on with ac but ac running and fans come on when they need to

  • taquecop Jun 19, 2009

    how do you access the blend doors without taking the heater box out, If I could just manually move it to allow cold air for now I could fix it completley later

  • taquecop Jun 19, 2009

    where is orafice tube and how much pressure does the system need

  • Richard Scordino May 11, 2010

    Narrower ac line should be hot not the large one if you just wrote it backwards, you may have a problem with the blend door in the heater box not moving.

2008 Grand Prix GXP keeps blowing the 10amp fuse for the AC. When replaced, it runs cold again until I start driving, then it blows and only has hot air once again. Very frustrating in Texas heat!

My 2002 TB a/c works for 20 min. Then does not. Checked , no leaks, clutch turns, condenser clicks until blowing hot air, replaced low pressure switch


Something to check because this has happened to me.....Make sure you have enough coolant in the radiator/overflow tank. IF the engine is running hot, the thermal switch on the AC compressor will turn it off to protect the compressor from overheating and damaging it. Don't go by the guage in the dash, it's usless. Hook up a scan tool and get the exact temp. Shouldn't be over 210 which is normal operating temp.

2000 pontiac grand prix ac problem


If the compressor is working, a mechanic would check the low and high gauge pressure.
The freon has to flow thru the system to work, and the cooling fan draws air thru the condenser to get rid of the heat from inside the car.
If the ac clutch is working but the gauges show equal pressure, the compressor may be faulty.

I have a 2000 Dodge Ram 1500 that will blow cold and hot air for only a few minutes. After that is only ambient air temps. It is a 5.7 ltr, automatic with only one set of climate controls. The heater core...


you say it will blow cold and hot air for only a few minutes. You don't say but I assume you mean will blow cold a few min. when turned on AC max , blow hot only a few min. when turned to heater hot. Assuming thats the situation and you say AC charged and shows good on the low side -you should charge the AC to a full charge on the low side will cause problems with the AC air compressor kicking on and off. I suggest while the engine is running and turned to AC cold max watch the AC air compressor clutch to see if it does indeed kick on and off if so charge completely. As far as the heater make certain you coolant is all the way to the top and the best way to do this is when engine is completely cold remove radiator cap and fill completely and completely close cap then fill overflow container just to the cold level. That should fix your problem.

Installed new air conditioning compressor in 2002 Pontiac Grand Prix - how much compressor oil do I need to put in?


If you have not cleaned out the ac system,the ac system will have oil in it,but,the compressor most likely does not have any in it,so pour about 4 to 5 oz in the low side opening on the compressor before installing it,and turn the center nut of the compressor clutch about 8 to 10 times,oil will try and come out the high side,when it does,this will be enough turning.If the system needs more oil,add as needed when freon is put in the system.If the oil is not added to the ac compressor before installing,the compressor could be damaged.Please rate if this was helpful,thank you.

2002 pontiac grand prix gt AC only blows hot air compressor full of freon and clutch spinning good temp control actuators working corectly narrow ac tube at firewall very cold thicker ac tube at firewall...


i had same problem 2 years ago. the actuator door tube was snapped in half and i used acquarium tubing to splice together. The tube runs along the passenger front well well inside engine and meets under the battery carriage. I could not tell anything was wrong without removing the battery to get a closer look. works like a champ now.

Also: there is also an inline venturi filter that fits in the aluminum tubing on the compressor, it may be clogged. You will have to have the freon sucked out to replace the filter. Check back with me so I can help more if this doesnt solve your problem.

Air conditioner turns on when car starts.


If only the AC indicator light is on but you are still getting warm air from the vents, this is not an issue.  Most newer cars run the AC compressor nearly all the time to prevent moisture accumulation inside the car.  Without the compressor running, your windows may steam up and hinder your visibility.
