yes i will have to tear into the harness when i got time. :waaaht: but i thought i'd try and see if someone had this happen on their kw before so i could save alot of time.as you guy are a big help on here.:)

Thanks for the input guy's but i'm pretty sure its a electric problem somewhere under the truck as there is alot of stuff running down on the drivers side..going to be $%^# to get to.
