Instrument lights and rear parking lights not working
Written by: fossildobber on Aug 21, 2011 10:37:52 AM
I have a 1990 GMC s15. The instrument lights don't work but the engine, battery, seatbelt lights do. The rear parking lights and reverse lights don't work but the signal, brake and hazard lights do. I have checked the bulbs, sockets, grounds, fuses and wiring and looks good. I don't know how to use a volt meter. Help please!

I have the same vehicle (1990 GMC S15) with exactly the same symptoms, passenger caliper was slow to release, changed both calipers and found lower flow on the passenger side then the drivers side. Did your situation turn out to be a clogged line?
