It is a complex switch that controls multiple functions such as the headlights, turn signals, cruise control, and windshield wipers on your vehicle. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE). Review: Exact replacement - AC Delco is the GM standard part. Look no further than here! - 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 Review: Highly recommend - Great replacement part, worked perfectly.

Refer to your vehicle’s Owner’s Manual for more information. **Q: How can I tell if my distributor cap and rotor need replacing?** A: Distributor caps and rotors typically need replacement when you notice engine misfires, difficult vehicle startup, reduced engine performance, corrosion or carbon tracking on the cap, or cracks or wear on the rotor. **Q: What is the difference between glow plugs and spark plugs?** A: Glow plugs are used in diesel engines to preheat the combustion chamber for a cold start. Spark plugs are used in gasoline engines to ignite the air and fuel mixture. **Q: Does the "Service Engine Soon" light tell me when my vehicle needs a tune-up?** A: No. The "Service Engine Soon" light comes on when the vehicle’s computer detects a minor malfunction, an engine emissions issue or that routine maintenance is needed. For more information, refer to your vehicle owner's manual. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Exact replacement - AC Delco is the GM standard part.

Fairy easy to install. ### ⭐⭐⭐⭐⭐ Exceptional Price for OEM equipment. PERFECT ! *by D***O on June 19, 2015* 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.
