Awesome instructional Video. I didn't realize this was a common fail on the multi switch since mine started doing the same thing...blinding others at night on a right turn. Eventually I just stopped using the right turn signal at night. In any case, got the new part ordered and waiting for it to come in so I can do the install.

[@baltoffice8694]

Thanks for the video, very well explained. Ordered new switch installed it today, it was 55 degrees in Baltimore today. It took about a half hour. The biggest issue was getting the boot back on around gear shift. Other then that it went great. Now I won’t blind anyone at night.

[@AdanChalinoOrtiz]

Blinded by the light, signaled right, now I'm blinding other people in the night. Lol 😅

[@ifrancus9623]

Best and clearest demonstration of this procedure. Nice work!

[@W0CES]

My 04 Yukon just started that so I am glad it's not just me! 73

[@darrinvw1]

Very very well explained Thank you sir

[@GONEZO38]

I found out what fixed my issue with my high-beam indicator was not the grease which I tried didn't work I replaced the signal switch GM Genuine Parts D6299A Combination Switch which fixed the problem for me

[@cynthiabailey3475]

Thank you for the instructions! Made it look a lot easier than I thought it was gonna be!!

[@CTUBS-sh5ww]

Cool dude. Very specific.

[@alpinehs]

Awesome video. Thanks

[@billyhead1625]

Very good job sir Thank You!

[@CalPil0t]

Interesting license plate collection...

[@jillturner2649]

Thanks. I have to do this on my '02 Chevy Trailblazer.

[@just_in_time5518]

Great content once again! You’re getting a lot of stuff done because of this coronavirus I think we all are in the same 🚣‍♀️ boat. I had to change that switch out once on my 95 f-350 once... it was not to bad almost the same kind of procedure like you did.👍

[@thesailors5372]

Same problem I’m having now and it’s so freakin frustrating. So I disconnected my high beams to avoid blinding people or to have them thinking Im blinding them on purpose then at night when I use right blinker the regular headlights go out until I turn off blinker..lmao so now I can’t see til my blinkers off.. but I’m just going to fix this crap ASAP. Thanks for vid

[@thesailors5372]

Fixed it a few days ago and problem solved. Thanks

[@fansalarmslightingetc]

1:41 & 8:16 are my favorite parts :) 7️⃣4️⃣1️⃣

[@5argetech56]

I will disconnect the battery. Just in case I might activate the Air Bag.. That would be a disaster of epic proportions!! *BOOM* Nice video! I need to replace the one in my 2005 Buick Rendezvous CXL!

[@SevenFortyOne]

Yes, that's a good idea

[@buzzsah]

Not heavy work but still a pain. I remember when screws were used, now its a snap-together puzzle.

[@brians9131]

Started with Hawaii plates. Ended with Alaska plates. Just by changing the multi switch . . . . . ; )

[@SevenFortyOne]

It's a magic switch 😁

[@jefffrayer8238]

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.

[@juanitopena6023]

My wipers on my 2003 Tahoe won't turn off. It cycles threw the speeds. Could it be the multi switch?

[@michaelmontana9571]

Where does the long wire on the multi-function switch (2017 GMC Yukon Denali) connect? I'm not able to locate where the old one is connected so I can disconnect the old one and connect the new one. HELP!

[@darrenvogel8096]

Could the multifunction switch be why my low beams aren't working, my high beams and driving lights work fine but both of my low beams aren't coming on, I checked fuses and relays and they all were good.

[@SevenFortyOne]

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.

[@EfTheTank]

Could this also be a reason my wiper fluid isn't turning on? Fuse, relay, and pump have all been replaced. I'm gonna give this a shot!

[@SevenFortyOne]

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

[@cyclecamp1]

Did you disconnect the battery to ensure that you would not fire off the airbag by mistake, or does this vehicle not have a steering column mounted airbag?

[@SevenFortyOne]

I like to live dangerously

[@1crazynordlander]

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.

[@dianaespinoza4188]

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.

[@SevenFortyOne]

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

[@kirkdouglas937]

That’s was good

[@baanjones5910]

Can this create start up issues with the vehicle? Eventually turn on after a while. The air conditioner, radio, and heater display randomly go out.

[@jefffrayer8238]

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

[@mhzrango]

My problem is i have no turn sinals or hazard lites on my chevy 2001 chevy truck .. my cruise control works as well as my wipers . Checked my fuses an all look good. Could this be similar problem your presenting. Thanks

[@SevenFortyOne]

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

[@larryshropshire4747]

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

[@juan71685]

Mine is a 2004 2500, when I turn the right turn signal the emergency lights come on too. I already replaced it but it keeps doing it. Do you all think the new one is also damage? Or something else is wrong. I got it at O'Reilly. Paid 195

[@syzygysyzygy8332]

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

[@102ibu]

Would this also cause hazards to come on instead of turn signals? Having that issue intermittently

[@SevenFortyOne]

It might...I'm not sure

[@urielramirez8699]

Good video Hey I got the same problem and I already change the control but after like 2 days still doing the same so I bring the control back to get my money and now idk what else to do I just buy a Chevy Tahoe 2006 some help?

[@SevenFortyOne]

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

[@gibfortune]

Does the multi function switch affect the brake lights?

[@SevenFortyOne]

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

[@gibfortune]

@@SevenFortyOne ok thanks

[@nmartin5551]

So after dropping too much money on new bulbs, im thinking it might be something else. Here i am. I have low beams some time, no high beams. I feel a new stalk and headlight switch coming on

[@devincrewesr]

Will this work for a 97 Tahoe?

[@SevenFortyOne]

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.

[@jamesharrison6201]

Hmmm, ac/delco is what is factory.

[@stevecarlson6462]

AC Delco is from China as well.

[@mhzrango]

Funny you im in the process of trying to fix. Let. You kno w. Soon

[@ryangeronimo509]

That's the problem with mine!

[@Mutt929]

I'm sure it's been mentioned or maybe not. Do your testing before you put everything back together. Especially if you go with the cheaper China part. My 03 Tahoe Z71 has to be replace now. It's identical in color to yours. My issue is the same as with my Silverado. Unlike you I'm constantly using my cruise control. Both my Silverado (02) and the Tahoe kicks off the cruise control when changing lanes on the highway. Turning on the left signal is good to go but when I turn on the right to move back to the lane, the cruise kicks off. This is both of my vehicles. Annoying

[@stevesutube01]

Those three holes under the bezel are not for screws. No clue why they're there, but there's not even a place for screws to screw into. Go figure

[@SevenFortyOne]

Maybe used in another application?

[@JonathanMoosey]

GM put too many controls on a single stalk for way too long. And even today they’re still doing the same thing.
