Question about 1991 GMC Sonoma

1 Answer

Left blinker problems

I have a 1991 GMC sonoma and the taillight was busted for about the first 6 months I had the truck. in this time it filled with water each time I washed it or it rained. I since bought new tail lights and new bulbs and now the blinker works fine but when I turn the headlights on the brake light on that side comes on and stays on. It wont blink when I turn the blinker on but then the left front blinker begins to blink real slow. Is this problem in the connector for the bulbs or is it in the wiring somewhere. I was thinking it could also be some kinda switch somewhere but dont know where to start. Thanks alot for your help

That's an issue with wiring somewhere alont the line. There has to be a short somewhere. Hopefully for you the short is from the new taillight assembly being installed and it would be relatively easy to get to. Hope it helps!

I think this may be the same problem these trucks have had for years take the taillight apart and check the circuts that go from the wireing to the bulbs dont know if this will help you also you can check the plug at the taillight to see if there is power there with the blinker on

All bulbs new but still dont blink on right blinker


The falsher unit on these vehicles is a thermal one therefore if the amunt of bulbs in the circuit is reduced then the flash rate is alot slower, remove rear bulb, clean up the bulb holder and the contact inside the holder.
Good luck Davelee

1998 gmc sonoma push button 4x4 busting diaphram vacuum actuator


On top of the transfer case is a vacuum switch with 3 vacuum lines connected to it. This switch controls when vacuum is applied to the vacuum actuator. This switch can fail partly and allow fluid from the transfer case to be sucked up into the vacuum lines and anything connected to them as well. When you replaced the actuator before, did you notice any oily fluid inside of it?
