The control unit circuit board was burnt when I took it apart. I repaired the burnt tracks on the board, installed it, turned key on. With blower fuse(F11) in, nothing happened. When I put the climate control fuse in(F10), the board started smoking again. Something is shorted, causing this to burn. My problem is, I can't leave it on long enough to find it.
WIll a bad electronic temp control unit(on passenger side by glovebox,at side of car) cause this? Can a dealer test this module,also blower control module?
