Blower doesn't work at high speed

you will need to replace the fans blower resistor. its mounted in the cab. in the lower right side of the heater box. some aftermarket suppliers are carrying the part but all chevy or gmc dealers will have it.
good luck chris

Changed battery now loss of rpm when ac is on

Check your Belt Tensioner. If the Tensioner is Not Keeping the Belt Tight Enough It will not allow the Alternator to Charge the Battery and it will cause a Battery Drain and will Pull on the Electrical System.Please Rate my Response, I need all the Help That I can Get! Thanks!

Digital ac controls don't respond and fan stays on whencar is off

The way to fix this is by changing the blower motor resistor.
I paid $138.00 at the dealership for a new one and it solved the problem.

The throttle body needs to be cleaned, make sure to clean both the front side and back side, this means that the throttle body needs to be removed from the intake. Also, disconnect the battery while cleaning, this will reset the computer and allow it to relearn to the cleaned throttle body.
