2007 Yukon has starting issues when its wet.

[kel]

My wife's 2007 Yukon has a number of issues when she starts it in the mornings after it has rained or there is a heavy dew. The dash gauges will not work, the blinkers don't work, the windshield wipers don't work, the doors won't lock, and the rear windows won't operate. When you turn the truck off and try it again, it won't turn over. If you wait a few minutes, it will start but nothing is working correctly. Once the truck dries, it operates normally. Anyone else have issues like this?

Sounds like muffler bearings are seized. They all go bad on the 07's.

Last time I saw a Tahoe have starting issues it was a bad ground in the kick panel. That was an '06 though. Check those first. Also clean battery terminals and check all the grounds you can find.

Is there a fuse panel under the hood, or kick panel? I had this problem in my expedition, had to dry out the fuse box under the windshield. Had to have the windshield re-sealed, then all was good. Check your fuse box connections under the hood and dash. Make sure there is no water inside of the box, and if it is, trace where it is coming from.
