Replying to: goddude (Oct 11, 2005 7:09 am) Chris...I do not have any of the problems you mention. What I was suggesting was to take the dash apart and see if any of the controls have come loose for the vent position switch. Until you can find the problem, in any of the vent positions, you will still get heat out. You just won't be able to defrost your windows. Bad in a cold climate. As stated, check for loose connections in the HVAC controls.

Replying to: goddude (Oct 11, 2005 7:09 am) Chris, I also have a 2004Cav. You have described my exact problem to a tee. If you find out what it is, please post it. I have checked vaccum lines,fuses,etc. I have found out nothing yet, but it is getting cold in the north. I do have recirculation and vent but nothing else. My A/C works but only out of the mid-vents and my heat will cook you out of the car. I just wish it was stuck on defrost too! When I put it on defrost, I do see the green light come on but that is it.I'm stumped.

Replying to: goddude (Oct 11, 2005 7:09 am) Chris, I believe the problem you have is a broken or kinked cable. If the green light comes on when you turn the knob to defrost, than more then likely it is the cable. Remove the access panel on the left side near the accelerator and the small panel that covers the brake switch also. You can see directly behind the switch that you are concerned with. I had to manually move the vent door because my cable was kinked and frayed.LEAVE the unit in defrost position for the winter or until you can get it repaired or replace the cable yourself.P.S. You need a flashlight. Good Luck!
#15 of 61 1996 Chevy Cavalier...Air Conditioning Problem by mtandst Mar 17, 2006 (8:58 pm)
Bought my Cavalier new and have kept up with it as I should with regular checks, etc. Have had several problems thru the years...most have been fixed...(except the persistent electrical issue with the ABS lights remaining on all the time...and something draining my 4 batteries way too fast)   I just noticed a week ago that the air conditioning system wasn't cooling. Took it in to a air conditioning specialist. They said they put some dye into the system...and they at first thought it might be a problem (with the schrader ? valve or the suction valve core ?) but when I checked with them a bit later...they said that they thought they detected a small leak at the casing of the compressor..maybe around 1/2 inch. They said that the cost to replace the compressor would be around $1,000 job and that would also include replacement of the accumulator. I just went ahead and paid for the dye and the service and the added R-134A. He said it may hold for 2 days, 2 weeks or 2 mos. So...I am wondering exactly what I should do about this.   I don't really understand why he can't just fix/repair the leak in the compressor vs. buying a new one. When I asked that question...he just said that he preferred to do it that way...to better guarantee or assure that my problem will be fixed. After all...he would hate to have me come back in to him...and have the compressor replaced after all and then have to pay all those labor costs all over again. Also, something about some seal/suction at both ends of the compressor...and some lubricating would be all new, etc.   If you ask me...it sounded like a lot of razzle/dazzle...and being a woman...I tried to stand my ground and ask questions etc. but...I really wonder...if I am being hosed.   Any thoughts on this ordeal...or if you have experienced any problems like this...I would like to hear from you.   Thanks in advance for reading Replies to this message: halsca (Mar 18, 2006 9:24 am) mtandst (Mar 18, 2006 11:37 pm) halsca (Mar 19, 2006 1:01 am)

Replying to: mtandst (Mar 17, 2006 8:58 pm) If the case is cracked any repairs probably would be temporary. Most mechanics prefer to replace stuff like A/C compressors rather than repairing them. You'd still have to pay all the labor charges anyway, it's better to go with a remanufactured unit in the long run.   All I can say is shop around to see if you can get a better price.

Replying to: halsca (Mar 18, 2006 9:24 am) halsca....   Thanks for your reply.   You are probably right...when you say that getting a remanufactured unit put in my car...would be better in the long run than having my old compressor fixed. I noticed that you used the words remanufactured...So...they are not NEW compressors that the repair shops put in?   Interesting?   I suppose...they will then take my old compressor...and turn it in somewhere and get some money for that...and then that place will work it over...and resell it again.

Replying to: mtandst (Mar 18, 2006 11:37 pm) Yes they turn it in to cover the 'core' charge. Places that rebuild auto parts charge more if you don't have a core or turn in a unit so trashed they can't use it.   I worked for years as a mechanic this is standard practice. Most mechanics don't have the stuff or don't want take the time to rebuild precision parts like A/C compressors, alternators or starters UNLESS they come from really rare autos. There are lots of places that specialize in rebuilding auto parts and MOST stand behind their work.
#19 of 61 Air condition problem by mervs Jul 25, 2006 (6:36 am)
Hi all. I am a new member here. I logged in to share my problem with you guyz and get some feedback. I have a 1999 Cavalier-automatic-2.2 ltr engine. Recently i started feeling a kind of choking in my engine when i switch on the AC. When the compressor is on, the engine becomes very heavy and there is a huge noise when i press the gas, if i switch off the AC, the engine is as smooth as it was earlier. What could be the reason? The dealer says there is no much diff...but i feel it while driving. Any suggestions guys? May be the compressor is weak? Thanks Replies to this message: k_erin (Jun 12, 2007 5:24 pm)
#20 of 61 Strange electrical issue - ecm or alternator related? by porsche_914 Aug 18, 2006 (6:54 am)
I have a 2000 Z24 convert., purchased used in 2002 with 10K mile, now has 67K miles. Have always noticed brightening/dimming of lights with concurrent speed changes in blower motor fan speed since we have owned the car, but it did not seem to affect anything other than to be slightly annoying. Yesterday my daughter was driving the car and noticed that the speedometer went to 0 [she was doing about 35 at the time], all the warning lights started flashing on the dashboard and the engine cut off. I had it towed home. It now starts and runs fine, the alternator puts ~14V across the battery. I am unable to recreate the 'surge/sag' observation with the car sitting in the driveway so I can't see if the alternator is cutting out. Battery is ~1 year old. Anybody have any ideas regarding where I should look next? Does anyone think ECM is involved? ---Thanks!
#21 of 61 2003 Cavalier heating and cooling issue by cav03 Sep 06, 2006 (11:17 am)
I'm having the same problem as mentioned above with the vent cable. Last winter the cable froze and when I tried to turn the knob the cable kinked and slipped off the control arm. I have managed to get the vent into the defrost position but would like to change out the cable. Does anyone know the best way to access this cable without pulling the entire dashboard out? Thank you. Replies to this message: gmoudy (Sep 13, 2006 2:38 am)
