#23 of 61 A/C crappy by ramanexodus Sep 11, 2006 (3:09 pm)
Hello again. A/C isn't quite up to snuff. Filled AC with refrigerant correctly after illing it a month earlier and was only able to fill it midway into the blue and will not go further up even after using a whole can. A day later the AC is still at the same spot on the guage but isn't really cold but makes it bearable. My father's Chevy Blazer (same year) had the same problem but eventually fixed itself. I'm going to use the refrigerant with stop leak to fill it again but I'm a little cautious. Advice or Green light would be a great help. Thanks for the help about the mildew.

Replying to: goddude (Oct 11, 2005 7:09 am) Chris I had the same problem. The cable that is connected to the back side of the control knob is kinked. Take the cover that is located to the right of the gas pedal off and the cover that is just above the break pedal off. You will have to lay on your back to reach the cable. The cable is located behind the knob. It helps to turn the knob back and forth to locate it. Pull the cable up and off of the back of the control knob and straighten it with a pair of pliers and snap back on to the control knob. You may have to follow the cable up to where it connects to the vent control and manualy move the vent control up and down a couple of times to get the cable moving freely. Good luck. It took me about 15 min to complete the repair.

#28 of 61 2003 Cavalier AC vents?? by connmj1 Oct 25, 2006 (1:06 pm)
My g/f's 03 Cavalier is having a weird ac issue. Air will blow from the passenger vent, floor, and defroster but not from the two middle and driver's side vents. The switch seems to be working fine, because I can hear a little air coming out of the vents. Is there a hose that connects just those 3 vents? Replies to this message: jshepp (Jun 21, 2008 12:31 pm)
#29 of 61 Rear Defog Broken by guerrgi Oct 30, 2006 (11:24 am)
My Rear Window Defogger is no longer working. Replaced the fuse (even though passed continuity test), the switch LED comes on and there is voltage supplied testing the pins at the back of the connector when the button is pushed. There are a purple and black wire coming out of the connector that backprobe fine about an inch or so but the purple one does not test continuous from one end to the positive window terminal. My Haynes manual doesn't show the wiring for the rear defogger so I'm wondering if there is a fusible link somewhere or a relay or something I should be looking at, or even where the heck this purple wire is routed to in the car. Any help?

I have the same problem, and I guess the same Haynes manuala s post 29. Wondering if anyone knows something about it.
#31 of 61 Air compressor by njohnson1975 Mar 28, 2007 (11:16 am)
I have a 1999 cavalier. the air conditioner is just blowing hot air. the thing is the compressor isn't kicking in. I think it is just a fuse. I've checked the fuses in the dash no problem there. Is there another fuse for the air conditioner that I can check before I go broke paying a mechanic. also I had a circuit board replaced (i think) but before it was replaced the air worked perfectly (it would freeze you out of the car. wanted to add that just in case. any help would be great. Thanks in advance. Replies to this message: gonogo (Mar 29, 2007 7:40 am)
