Having problems with your 2004 GMC Yukon ?
2004 GMC Yukon xl......If I put left turn signal on, the emergency lights flash. Found a burnt bulb for brake light and changed it. Problem persist. Emergency flasher switch still turns on flashers properly and right turn signal works,
That vehicle has all three switches attached to the same module. Spray a little wd-40 into the flasher switch. Sometimes the slide on the flasher switch gets a little sticky and won't allow the turn signal to work independently. If that isn't the case, there is a repair kit for that available on ebay. the module of course costs around three hundred to replace but could possibly be found at a boneyard for much less. Also, check ebay for that module. Hopefully the WD-40 will fix it. Good luck.
