Chevy/GMC Truck and SUV Multi-Function (Blinker) Control Replacement 

Fixed it a few days ago and problem solved. Thanks

It's a magic switch 😁

I noticed as well, went back to make sure I wasn't crazy. Excellent video. No problems yet but nice to know it can be changed easily.

Yes, that's a good idea

I can't say for certain but it is a possibility you have a bad switch. You may also have two bad bulbs or some other wiring problem.

Maybe...unplug the switch and see if it stops.

I like to live dangerously

I think that is why GM designed the multi-function modular switch so you could disassemble portions of the steering column without fear of setting off the air bag. Earlier models were a little hairy as you had to pull the steering wheel to get to the turn signal switch. I worked at a GM dealer and watched all the service videos even though I was the parts manager. These earlier airbags had to be jumpered after a disconnect as to prevent static electricity from firing the air bag. The airbag harness is well marked. Even so if the procedure in the repair manual said to take precautions to keep the airbag from deploying you can bet that a technician that is doing the procedure is getting paid by the job and not by the hour you can bet he/she is taking every shortcut possible so they can put shoes on their kids' feet and jewelry around their spouse's neck.

Soooo… is it not necessary to disconnect the battery, or should I do it??? I need to fix my switch, but dunno if I really need to disconnect battery. It’s dead now anyway bc the high beams won’t turn off anymore.

Disconnect the battery.....it's certainly won't hurt and could prevent a freak accident

I don't think the brake lights have anything to do with this switch. Check the factory schematic to be sure

@@SevenFortyOne ok thanks

I've heard some of the aftermarket switches aren't very good.

It might...I'm not sure

Check the grounds, common problem, lots of vids about grounds on the GM800.

Maybe....I'm not sure. I no longer own this car. Are the hazard lights controlled by that stall too or a separate switch? If separate I'd look elsewhere for the problem

@mhzrango did you clear up your problem by changing this part? My 2006 Silverado is doing the exact same thing as yours.

Follow the harness wires coming out of the switch, this sounds like a short due to damaged insulation.

I don't think this exact part will work but you should be able to find a similar one on Amazon or maybe a place like O'Reilys or AutoZone.

Maybe used in another application?
