Remote start

[brimstone]

truck starts then dies...does it 3x.
front heated seats ...no workie
third brake light out..
all happened with in a week or so of eachother.
before I spend 2 hrs searching the forums for help.
I think I can figure out the last 2 this weekend, been too cold to bother. But running out at 2am in my pjs to warm up the truck is really annoying me

Sounds like the bypass module for the anti-theft system. I had to replace mine 3 times. Hoe did you get your heated seats to work with the auto starter? Thanks.

yep. sounds like either like an interface issue especially if your Yukon is a newer model. What remote start and bypass do you have installed? The 3rd brake light is probably just coinsedence.
