My dad has a 90 GT vert and he's having a problem with his defroster and heating. Even if the A/C dial is in the off position, the defroster is still on. You can move it to vent, A/C, defrost, floor, ect.. and it still stays on. Anyone know what could cause this? Also his heat doesn't work very well at all. It only seems to blow out cool air? Thanks for the help.
