2002 GMC Yukon V8 Four Wheel Drive Automatic 92000 miles
I noticed that my security light came on and my door locks quit working. Car turned off the security light doesn't flash anymore just stays on solid. Locked or unlocked when the door is opened the factory alarm goes off. I have switched relays around bought new ones and nothing. Still doesn't lock or unlock. What to do now? The only thing I can think of is taking it to the dealer.
