Cabin air on constant high - 5/8/2008 1:14:44 PM    chuckyspoons   Posts: 2 Joined: 5/8/2008 Status: offline This is sort of an annoying problem. My air is stuck on high and will not turn off. I have to actually either disconnect the battery or remove the fuse for it turn off. For a small time period prior to this i was having trouble with the air actually coming on. Every so often it just wouldnt work. Now maybe a month later its the reverse. At this point I've removed the fuse to stop the air from blowing. I've gone through all the relays and none of them seem to relay anything to do with the cabin fan since when I pulled them out the air continued to blow. Anyone ever heard of this ridiculous problem before or have any ideas on what it could be? Post #: 1

Just happened tonight but I had earlier issues (about 6 months ago) where the air periodically wouldn't come on. Seemingly resolved itself after I brought the car in for a look on other issues but I guess not. I was driving with the air off (just got my car back after the 45,000 mile checkup, second time I've driven it) and the air came on full blast. Adjusting the air has no effect nor does adjusting the vent output. Air stays on high even when the car is off, nice. I had to disconnect the battery to get it to shut off but it comes right back when I reconnect. I guess I'll look into the manual to find out which fuse to pull, btw does anyone know whether keeping just the positive connection on the battery will drain it? I've got an appointment this tuesday (lock system failures) and will certaintly have them take a look. I'll make sure to swing back by to give you guys an update. Glad I'm not the only one, I guess [Edit] (This is also a 2003 9-3 Linear) < Message edited by gnosis -- 5/24/2008 9:29:12 PM > (in reply to chuckyspoons) Post #: 7

I can''t adjust the air and when the car is off and keys are out, it still blows at full blast??? Anyone of you guys find a solution yet? (in reply to gnosis) Post #: 8

The part for my lock system failures is still not in (3 weeks +) so I haven''t been back to the dealership yet. (in reply to lopeztm) Post #: 9
