    the fan still blows when I cut the ac on...it's just not cold. and my boyfriend hooked a pressure guage to the low pressure valve and it was blowing into the red zone...so something is defintely wrong. :-(

    Does the blower works on any speed or is it just not putting out cold air ?

    I had the same problem. I had a full charge of freon. On the opposite side of the engine compartment from the A/C compressor is a A/C line. There is a pressure switch in the hose with 2 wires coming from the switch. The plug was dirty on mine. I removed and cleaned the plug, reconnected it, and viola ... my A/C works again.

Your system uses r-134a as the refrigerant. Freon® R12 was outlawed some years ago.
It looks like you may have lost your r-134a. You will have to get it replaced. When you do, be sure
to have an ultraviolet tracer dye added. This will be used to detect the leak you appear to have.
When the system is recharged, your mechanic can take a black light (yes like in college)
and check for leaks. If something has bump against an AC pipe the O-ring seals may be loose and would need to be replaced. The test will show it.

You most likey have a empty system or low freon charge due to a small leak.

Hi! I have a 2006 Saturn Vue 4 cylinder with 91,000 miles. I always keep my AC on max. The other day I turned the temp warmer. Well the next morning the AC stopped blowing cold air. I noticed before...


The car will idle funny due to the air-conditioner on ,when on it takes power from the motor about 10-20hp depennding,and with the air on all the time its robbing you of fuel mileage.put the temp back to cold and use norm-air max should be used to get real cold and then switch to norm.if you want warm air,then put on vent and stop wasting fuel,with a.c on when you have it on the red area.

Air conditioner, fuel gauge, and temp gauge all stopped working at the same time


Three possibilities;
All related to blown fuses,

1- Fuse blown in the engine compartment LH.
2- Fuse blown in the cabin forward LH below the dashboard (below your legs left hand).
3- Fuse blown in the harness (wire bundles) below the dashboard very easy to reach with your hands “just look underneath steering wheel ".

U said " The air conditioner blows, but the air is not cold.
" Yes only the fan working which might receiving power independent all from those other mentioned things.
If all fuses OK. Then look for broken wires.
