This is an exact match for the broken switch on the driver's side door of my 2000 GMC Sierra 2500. I spent about 10 minutes finding and fishing out the disconnected wire, threaded it through the hole in the side of the dashboard, plugged in this switch, stuck it into the hole and I'm back in business.I am increasingly becoming a huge fan of buying parts on Amazon for my sadly aging fleet of cars, trucks, ATVs, motorcycles, trailers, boats and motorhomes. I've bought many parts for my old Sierra in particular. I always check Amazon first since at least 8 times out of 10, I find what I'm looking for and either at the best price or an acceptable price. This allows me to keep the old toys limping along until the next thing goes wrong. Also, reading the reviews invariably gives me excellent tips on what to do (and more importantly what not to do, although I never seem to learn).Regards, Mark
