Question about 1999 GMC Yukon
I have a 1999 yukon SLE 5.7 4wd. The brake lights don't work nor do the rear turn singals. The front turn signals blink fast. I changed the bulbs and check all fuses. Is there a relay fuse/switch I'm missing? i see nothing in the owners manual. The third top light works, running lights work, just no brake or turn signal lights.
I had a similar problem on a 99 yukon. The lights were burned out. When I replaced them the lights still did not work. I talked to an older friend of mine and he recommended some lithium grease. Spray a little grease on the old socket prior to installing the light. Plug in the new light and wiggle the light and it should work.
This drove me crazy for about two weeks.

I had the same problem last week, but it ended up being the turn signal switch in the steering colum. This is a master switch for turn signals, brakes and E-flashers. The part cost $234 at your local auto parts store. The mechanics book says 3 hours to replace. A friend and I replaced in just over two hours, but it was not easy at all. To do it correct and get at the mounting screws with ease you need to pull the steering wheel which we couldn't figure out how to do that.
