GM Genuine Parts D6254E (20940099) Turn Signal and Headlamp Dimmer Switch

This product was identical to the switch that I removed from my 2007 Cobalt. All numbers molded into the plastic components matched, electrical connections matched, and looked the same. It took me less than 10 minutes to install (three 9/32" socket head screws to remove and reinstall upon completion). Works like a charm and I saved at least $40 compared to buying from a dealer or parts store. Search YouTube for installation instructions or read mine right here:1. using a small flat head screwdriver, pry the plastic horizontal trim pieces from both sides of the steering wheel back enough to get your fingers behind them...then pull them out. It takes some effort to pull them out, but they will come out. There are two metal clips holding those pieces of trim onto the dash.2. using the 9/32" hex head socket on a screwdriver attachment, remove the three screws from the underside of the steering wheel column.3. lower the tilt lever from the underside of the steering wheel and then pry the steering column apart. It is made up of a single top piece and a split (two piece) bottom. You can pry it apart with the screw driver or with your hands. Leave the top piece in place...just loose.4. Using the small flat head screwdriver, pry the retaining clips that are on the existing turn signal switch (down on the top and up on the bottom) until you hear them click.5. Slide the switch out of it's receptacle. You may have to wiggle it a little to clear the top dash trim.6. Remove the two electrical connections from the switch (squeeze the smaller connection tab and pull it out, and use the screwdriver on the larger connection tab to pry it enough to clear the plastic tab).7. Install the new switch. Make sure to pry the two retaining clips up after pushing the new switch back into the receptacle. Those clips will make a loud click when they are seated properly. Then reassemble the steering column cover and raise the tilt steering lever. Finally, snap the two horizontal trim pieces back into the dash on either side of the steering wheel.That's it! Installed, and you saved a ton of money...especially compared to having a service garage do the repair for $250 or more.-James

This thing just works, as a replacement for the ailing GM one. I saved some money, by going this route, and I'm happy I did-- it seems to be identical in every way I could see, to the old GM one I removed. Same markings. Same tiny printing, and so on. I did have a bit of fuss and bother teasing it past all the other things in the way, but a bit of gentle persuasion with a flat screwdriver (like using a shoe horn on a stubborn shoe, not like a lever prying up a nail...) it snapped into place.I was expecting that, as removing the old, busted one, faced similar issues--not enough clearance to simply pull free from it's socket (once you release the tabs). I see why GM's manual outlined a much longer replacement process, as it suggested removing far more things in the dash that I did. You could do that-- or? You pry the old one out, because it's *broken*already* so nothing to lose. And using that knowledge, you carefully tease the new one back in. You know it's in, when it snaps in place, and the secure tabs lock down. A quick engine-running, driveway test confirms all lights working as expected. Later on, when it was dark, I tested the auto-on feature of the headlights, making sure the bright/dim function worked too.Good enough. Recommended.

This part is a direct fit. It was a good price for a genuine part. Not hard at all to remove the old part & re-install the new one. Took me about 30-40 min, and most of that time was studying and rechecking my steps so as not to mess anything up. I've had the part in about 2-1/2 to 3 weeks now. So far so good.

To have to take your car to the dealership for anything is like watching your money being siphoned away without your knowledge. YouTube has videos about turn indicator malfunctions (when you make a turn and your turn indicator just stays on without automatically clicking off). This piece replaces the entire assembly and ya don't have to be a mechanic or technician to install it in your vehicle. It also controls headlight functions. The YouTube video actually explains how to fix the turn indicator problem without having to buy this module, HOWEVER, I like to have spare parts and for the price paid ~ it is OEM perfect. I will be looking into other items that Amazon carries for my car (2008 Solstice GXP - Pontiac). As you know, Pontiacs are no longer made by GM. This part fits several makes of GM vehicles. To have this repair done by a dealership is between $200 - $400. You can do it yourself, and pocket that cash for more goodies at Amazon or a night out at a nice restaurant. What have ya gotta lose?

Looks identical to one I was replacing. Watched a YouTube video on "how to install". YouTube makes it look so easy and claims it only takes 10 minutes. It took us about an hour and I also wound up breaking a small plastic piece in one of the steering wheel side covers (as a result, it did not reattach, so I had to get creative and use a piece of Gorilla tape). Also, this device was suppose to simply go right-in and click, it did not. It was a tiny, tiny bit longer and as a result it did not latch and snap as it was supposed to. We pushed it-in as much as we could, being cautious not to break anything else. I also made a slight modification and it is secure enough! After getting everything else reattached, my steering wheel rubs a little bit …. nothing ever works same when reattaching! (try to get someone crafty to help you!) But more importantly, my Car's left turn blinker now works perfect, as do all the other functions! I only took away one Star due to fact it did not 'click' when I pushed it all the way into the crevice (it was tiny, tiny bit longer….but not noticeable and not really a big deal if it does not "click" all the way in, it'll still be secure enough, and more importantly, works!)
