I have a 2002 GMC Safari van. My wife went outside to try to start but it would not start. She tried a little while later and still would not start. I tried a few hours later and she said she pushes down on the gas to start so I thought that was the issue since it is electronic fuel injection.
When I started it up the turn signals would not work and I found that fuses 1 and 16 were both blown. I researched the issue and thought it was the multi-function switch so I bought a new one off of eBay from a reputable guy who had old dealer stock. It looked brand new. I installed after a very difficult process and when I pressed on the brake pedal it blew the fuse again. Putting the turn signals on also blows the other #16 fuse after blinking on and off for 3-4 iterations.
I removed all the dual filament bulbs and the top brake light and pressed on the brake pedal and that also caused the #1 fuse to blow.
I removed the brake signal switch and opened it up gently and made sure the front two contacts would be coming open prior to the last contact touching. Everything looked good in there.
The van does have a connection for trailer lights and brake controller. I reviewed those and they are all clean.
I removed the top brake light and everything looks clean there too. The resistors all look good.
I opened the sliding door just in case something was shorted in in there as well but that had no effect.
Any suggestions on how to test the actual connector sockets into which the bulbs reside?
I really thought it would be the multi-function switch but that was not it. Please ask anyone you know who may be able to help on this one as have a $4,000 boat anchor right now.
have the same problem?
