2006 GMC 3500 Sierra LT. Heater Blower would not turn off.

from the Chevy Dealership. They double checked the part# and my vin is not part of the recall!

When I first replaced the Resister the blower was working everything seemed ok. But the next morning when I started my truck... No nothing came on. I will check the voltages. I checked voltages... turned the control to 75 and med speed for blower. pulled the wire plug from the resister and 0volts.

The tempature setting dosnt matter. When your checking voltage you should be checking it at the blower motor on each speed. It sounds like you have no voltage at blower motor from what your saying. If this is true check for voltage going into resistor. You may have been given a bad resistor.
