    i have a problem eith a 03 silverado that when started it goes thru self test of the vent/ defrost system and goes right to defrost mode after going thru all modes.
    I am looking for a copy of TSB 040138008 and cant find it on the web any one have copy??
    What could be causing this problem, all i did is replace the truck battery.
    I have reset the system by oulling the fuse and disconnectiong the battery with out any luck........Thanks
