Problem for Chevrolet 2001 Tahoe
My ac doesnt work in my 2001 tahoe
By jchheaster on Jun 25, 2009
my ac doesnt work in my 2001 tahoe. i bought freon for it. the compressor is not kicking on when i turn the ac on, but the gage shows in the red when i hook it up to try and put freon in it. i shot a little in it and the compressor kicked on and off. the gage then went to the green when it kicked on and then went back to the red when it kicked off. any ideas?

the a/c system needs a minimum pressure before the system will run. the system must have a leak so just buying freon may last a day or a few months depending on the size of the leak. also leaking freon into the air is ozone depleating, it should be recovered properly.
the system needs to be recoved of all freon. vacuum to -30psi held checked for leaks. (uv dye or nitrogen and soapy water). leaks fixed. vacuum to evacuate moisture and air. refilled with proper amount of freon (too much or too little make the air not as cold).

- it's low on freon. add it in slowly until the comressor stays on. then keep adding until the vent temp gets cold. if it starts to get warm when adding you have to remove some. pressure should be something like 30psi low side 180 high side. there may be air in your system so it may never be really cold.Yes
