I have a 1999 chevy 4x4 two door tahoe. Passenger brake/signal is not getting any power, all other lights work. Front turn signals, headlights, all running lights, both reverse lights and the drivers side brake/signal work. The passenger side turn signal blinks like the bulb is out but all the bulbs are good. I checked all the connectors up to the firewall and the passenger side brake/signal green wire wasnt showing any volts. All fuses are good. The problem is somewhere inside the cab.

Brake signal switch? But the other brake lights work

Multifunction turn signal switch? all other turn signals work including passenger front

Turn signal relays? all other turn signals work including passenger front

I dont know what it could be? Any ideas?

 

All of the rear lights go through the multifunction switch except the third brake light. It is a very common failure although I can not be sure if I have ever seen one side failure. I have seen many problems with the tail light sockets. For sh*ts and giggles plug the remove the drivers side and plug it in to the passenger side.

 

Already tryed switching them. See my problem is Ive been doing a bunch of searching and havent heard of a multifunction switch just effecting one side like that. I hate to change that thing out and still have the same problem.

 

They are 2 separate circuits coming out of the switch. Do you have a test light? What about a wire diagram? Broken wire are unusual unless it has been in a major accident or someone has installed a bunch of electronics.

 

I have a wire diagram but it doesnt go all the way to the multi function switch. I have a multi-meter I have been using, I bought it like this so it could be anything. So it is a possibilty that the multifunction switch is bad, because it has circuits for either side?

 

Yes it is possible.

 

Alright im working on getting the multifunction switch out but im having trouble removing the airbag does anyone have any pointers?

 

The service manuals say to remove the air bag but you do not have to. What I use is a torx bit that fits in a ratchet screw drive or a drill. you can then turn the bit with a 1/4 wrench.

 

It was the multifunction signal switch, good to go now. Thanks for everyones help
