  1. The one thing that should be mentioned is weather your truck has an Air Bag, some of the 3/4 tons did not as I just found out with my 97 GMC . Also steering wheel assembly is different.

  2. You can get the top of the multi function switch cover off by prying off the thumb & finger wings off of the switch. Yes it will snap back on when you are done.
    Also, you do not have to pull the Steering wheel to replace the multi function switch, but you will need a T-25 Torx driver shaped like an Allen Wrench to remove and replace the bottom screw holding the multi function switch in place.

  3. thanks a whole bunch for the instructional videos for replacing the multifunction switch. It saved me mucho $$$;  $120/hr  (would have been about 2.4 hrs according to GM dealer) and either $528.68 OEM for new GM Multifunction switch or $389.04 After market. Total would have been 816.60 or 676.99 PLUS the diagnostic fee of 99.95. Holy cow!!. The hardest part was removing the air bag; I pulled the steering wheel but bought a cheap made in China puller that bent & the tip of the center bolt got messed up but luckily I pulled on the wheel hard enough to remove it. Needles to say you get what you pay for… I did find out how to remove the ignition switch key part because the mechanic at the GM dealer broke off the screw hole on the top column cover! After spending time removing the ignition switch & trying to glue that broken piece everything went smooth.Again, I really appreciate you putting up this video.

  4. Good video. Doesn't answer every tiny little question, but gives most of the info needed to save a boatload of money. Repair shop quoted about $725, over $400 of which was the part itself. I got the switch on ebay for $37 and spent about 4 hours switching it out. Not an easy job, since the work is under the dash and a cramped space, but worth it in the end. I used videos from the same guys to do a front brake job also on my '99 Suburban and it saved me several hundred $ too. Good job and thanks for the videos!

  5. you guys rock! great step by step guide on replacing parts, really appreciate it and keeping my 1996 K1500 in good shape! Love to see one on swapping the engine for a HT383, you guys should sell that as that's my next big project, 250,000 miles and still going strong, but I'd like more power.

  6. Did not do this switch but I did the ignition switch on our 97 jimmy. What a pain. I wish I had known about your videos beforehand.

  7. First let me say, this video was a big help. With that said you don't have to pull the steering wheel to change the switch. I was able to get to both torx screws on the switch without removing the wheel.

  8. I recently replaced my idler/ pitman arms, and I must have bumped it and my steering wheel if off to the left by a few inches. Can I do this to straighten it back center again? Thanks for the video, and your time.

  9. Great video.  I was able to get everything switched out, but when all was said and done, my left front turn signal and radio do not work.  
    Can you provide assistance?


  10. My new switch is installed, but i noticed a problem. While on cruise control, occasionally, when i activate the right (and only the right) turn signal it disengages the cruise control. Also not sure if it's related, but about 6 months-1 year later my wipers started working only intermittently and now they only work on high. Related?

  11. I have a 1995 chevy 1500 I bought this truck and the guy gave me a new multifunction switch with it. The guy I bought it from tried to replace he but couldn't figure it out. And when he did he never reconnected the cruise control. I replace the switch now according to your video but I can't figure out where is the cruise control wire is supposed to plug into it. I watch the video but it's kind of hard to see. Can you tell me where it's supposed to plug in to.
    Thanks cole

  12. Needed a Multi-function switch for my 2002 GMC Sierra, dealer wanted $790.00 to repair, bought it at for $87.50 and replaced it in 2.5 hours, thanks for the video and the great price on the part.

  13. Thanks for posting, Mike. It was a big help.

    A few comments:

    – The hint to twist and pull on the horn wire connector, and the information about the cruise control clip lock, were particularly helpful. There was nothing intuitive about those connections. (On the latter, it would have been helpful to be a trapeze artist contortionist with half-inch fingers.)

    – Great idea, using the 4mm socket to deal with the goofy "male Torx heads" that secured the upper portion of the plastic housing.

    – My steering wheel came off so hard I was afraid I'd break the puller. I added some penetrating oil and a few moderate hammer taps, then let it sit while I dismantled the rest. Then it finally came loose. For reassembly I put some anti-seize compound on the shaft to make it easier next time.

    – Rather than use a socket to remove the top Torx screw that secured the switch, I was able to bend the upper plastic housing a little and stick a regular (screwdriver-like) Torx driver down through the hole for the hazard switch.

    All in all, the job was a royal pain — but it could have been a lot worse without your video. Thanks again!

  14. I managed to remove the 2 screws of the turn signal switch without removing the steering wheel, but the turn switch wont come out, is necesary to remove the steering wheel o something else? or there is another screw i missed up? or maybe the turn signal lever got stuck with something? any idea?

  15. Could the multi-function switch be the cause of my brake lights flicking? As I push on the pedal the brake lights work, however, the more I push on the brake pedal I get no brake lights. Replaced brake pedal switch.

  16. I know this video isn't to far off of what I am looking for. I can't find a video on the 98 GMC Steering Column Shift Mechanism. What I can only assume is cast aluminum broke into 2 peices. Have you ever though of making a video on something like that? I have found 1 video but it was for a ford car. Thank you for all you videos you guys are great.

  17. On my 91 GMC 2500, when I turn on the brights, they start to turn on then all lights in the truck go dead, instrument, markers, brake lights, EVERYTHING.  I can't figure out where to start! I've had a couple close calls with trees when it decides to do this to me in the dark.

  18. On my 1995 silverado the headlights cut in and out if i tilt the steering wheel or jiggle the turn signal, and sometimes will kill the engine, could the turn signal switch be faulty?  

  19. Hi I have a 98 gmc will this also fix my emergency lights …they work but once the brake is applied my hazards will freeze untill you release the brake

    Hi, I have a 2000 chevy camaro, when I turn my turn signals on the arrows don't show up and the lights don't blink on the back or the front. I saw that there was no relay switch hooked up under the dash. I put a new relay in And tried to start the car and it would take a while to turn over, almost what the symptoms would be if I needed a new battery. After the car starts the fuse for the turn signals is burnt. Once I take the relay out the car starts like normal but still obviously no signals. Please help!!

    You may want to take a look at that circuit to see if there's a frayed or pinched wire, that may be blowing the fuse. Hope this helps you out. 888-844-3393

  22. It is definitely the switch. My truck was doing the same thing until I jacked with it. Now my fuel pump won't even engage. Crazy how a hazard switch will kill an entire truck's electrical system

  23. Very useful and detailed with video. Dealership wanted 800 bucks to do this parts and labor… I got a new switch online for 50 bucks and had the old one out and new one in in 3hrs… Yay 1 A Auto

  24. You guys are the greatest . Thank you for the great parts an info. Your tec made it simple to under stand even my 18 year daugher under stood him.
