Messing with the buddies 08 Yukon today and it has a few electrical problems for sure. All fuses check good.
The remote door lock module would not work, so we replaced it with new and programmed it. Now the remotes work. Yeah!.
The TPMS system is acting weird. You can program it and it reads all 4 tires fine. As soon as you turn the truck off it forgets everything and will happen every time.
The Fuel pump works without going through the under hood fuse box. It does not even have a fuel pump relay in it.
When trying to remote start it, the headlights flash but nothing happens. And…
I su*k at electrical
