No wiper power, no radio, no blower (heat/cool)
Hi all,
I have a 1996 GMC 3500 HD w/ 85000 miles on it.
Suddenly and simultaneously my windshield wiper won't turn on, my radio stopped working and no air is blowing from my vents. Checked all the fuses both on the left side of the dashboard and under the hood and all are fine. Checked for 12V at all the terminals and have it. At this point I'm assuming a relay has crapped out because of all 3 failing at the same time. No voltage to the windshield wiper blower or fuse terminal for these three components. Does anyone know which/where the relay is found? What else could it be? Thanks much in advance....
Replaced 50 Amp Ignition2 circuit breaker
Had a 1995 C1500 with the same problem. Found that the 50 amp Ignition2 circuit breaker under the hood was blown. Replacing it restored wipers, AC, and radio.
