Heater fan will not shut off even when ignition is turned off and key has been removed. chevrolet parts tells me that there is no blower motor relay in this vehicle. Any ideas?

I would call this an automatic climate control system for the front of the passenger compartment. It has individual thermostat settings for each side and the ac/heater seem to function as needed automatically.

OK that's kinda bad for testing purposes, but I will send you a file by email. This shows test procedure, but without a GM Tech II scan tool, you might not be able to do much with it... You could pay for a scan at a local garage that can read "B" and "U" codes, and then repair it yourself...

Thanks, I do not see the file you referenced. This truck is under a 12/12 warranty for a bit longer. Guess I should take it to the shop.

I emailed it to you, If you didnt get it, I'll resend it, but If you have a warranty, RUN back there and save yourself a boatload of cash!
