The controls work and change and all that good stuff, but the blower doesn't run. Would it be the motor or could it be a fuse? Any other ideas?

This is my buddies ride. He just got it from an auction and it has 165k on it

 

Probably has a melted blower resistor assembly and melted connector. Drop the has panel on the passenger side under the dash. It's a 6 or 7 pin connectorl in a straight line that plugs into the resistor it's held into the case with 2 screws. Look at it and see if it's melted and unplug the connector and look for melted and or heavily discolored pins. If melted get parts at nearest gm dealer

 

lol, that's what it was. He brought it to a dealer and had it fixed

 

Thanks for the update always appreciated
