ok, so my gf's heater/ac blower stopped working a couple months ago. she has an 88 t-bird 5.0 i replaced the switch and it worked good as new. now it will only work on the second setting. theres 4 settings on her car and it only works on the second to lowest setting. and thats if it works at all. wtf is the problem with this pos car?! When i originally replaced the switch it was melted. i was told that the stock gauge on the wires isn't thick enough. it's about 8 degrees out right now so i'll be working on it tomorrow. is it the switch again or what?
