I don't have the owners manual and was wondering how to reset the overhead Information Center
and number two I have no heat when the truck is warm and you shut it off and start it up again it will blow heat for about 3 seconds and then you can hear the door I want to say close on it blowing cold air immediately Weber had this vehicle before me install an aftermarket radio just wondering if something got crossed when they did this any suggestions??
its good and cold here in Wisconsin and with a 1 hour drive to work at 3 a.m. it gets pretty cold

 

I'm sorry I don't know much about them. However, the door/flap you're talking about is usually vacuum operated. It sounds to me like you might have a vacuum leak somewhere.

 

it's electric over vacuum,....unplug it and check for cracks or crimped line

 

Manual HVAC or Automatic Climate Control? The temperature blend door actuator is all electronic on both systems, so the diagnosis procedures are different. Broken gears in the actuator is a fairly common problem on both systems.
