Hello everyone, new to the site. Just purchased a 2002 tahoe and the rear heat/ac doesn't work. The controls up front do not do anything, if I turn it to full blast nothing. It doesn't matter if it is heat or ac, it just doesn't make the system blow any air at all out of the rear vents. The front ac/ heat work just fine. Also, there are no rear controls. The previous owner removed them when he installed a tv in the ceiling. Would the fact that the rear controls are disconnected be any reason for the rear system to not be working? I've read some of the other posts on the site about the rear system, but all I could find were folks that were only getting heat or cold. I get absolutley nothing?
Any ideas as where to start? Could it be the front control unit wires came loose when the installed the tv? Are there any control circuits anywhere that could be bad? I checked the rear ac fuse and it is good. I wouldn't think the fact that the rear passenger controls have been removed could be causing it, but then again I've been wrong before.
