ok about 2 weeks ago i installed my dvd player and took off the center dash and my cold air stopped working. even when i put it in the cold position i just get hot air. when i took off the dash it was in the hot position. so 3 days ago when i took out the dash to remove the dvd player i looked to see if the wire broke for the hot and cold air. and it works fine. but still no cold air at all just hot. so can someone help me out with this problem.
