Having problems with your 1989 GMC Sierra ?
1989 - GMC Sierra 3500 4x4 has 2 issues: 1) dash brake light flashes with engine on, but repair shop says all brakes are functioning properly and pads and rotors are OK & safe to drive, but they don't know why the dash brake light flashes. 2) Truck starts fine and runs fine. After driving for more than an hour and cutting off engine, engine will not start until it sits for about 10-15 minutes. Lights come on in dash, but no clicking, no sound, does not start. Also, notice after about an hour of
Put a remote starter cycloid on the firewall that's hooked to the one on the starter to get rid of the having for it to cool in order start it. At least that solved my problem. As for the brake light flashing..well mine does too but everything works....it's most likely a short somewhere. The biggest problem is driving off with the parking brake set. As for the hood. My paint is fried as well. I think it's because there is no insulation installed under the hood. Who knows. Good luck
