i jsut installed my turbotimer on my sti, after i finished, i noticed my air conditioner isnt working. when i drive on the freeway and leave it on heat, hot air comes out. does anyone have this problem, or know how to solve this?
See if the compressor engages when you push the AC button in and turn the blower fan on. Also see that the AC button light lights up.
Where did you splice in for your timer installation (did you splice at all or use a harness)? Check that you've not loosened a wire or ground connection under the switches -- all this assuming you didn't knock a duct off if you were fiddling under the dash etc.
OK, in essence you don't have an AC problem -- you have a blower fan problem. Although blower motors can and do fail, this is unlikely in a newer car. Most likely, you've either knocked something loose or shorted something and blown a fuse. It's just a matter of backtracking through what you did recently under there and checking things, I'm betting.
