Kezza99 Posted July 1, 2011 Share Posted July 1, 2011 Hay all. So i recently installed a head unit in my 96 TSR wagon, and now my heating or A/C control unit wont work. The buttons illuminate, but they just turn on when i turn my headlights on. The display screen doesnt work and when i push the buttons nothing happens I've checked all the fuses. there is no voltage across the heating fuse holders in he fuse box down by the steering wheel. Relays are yet to be tested Any ideas? Cheers =] Link to comment Share on other sites More sharing options...

Kezza99 Posted July 2, 2011 Author Share Posted July 2, 2011 I just cut all the wires on the harness of the factory radio. Link to comment Share on other sites More sharing options...
