Air Conditioning problem
2003 Chevy Blazer 6 cyl Two Wheel Drive Automatic

The blower for my A/C is not working. Problem seems to be between the controls and the blower itself. I want to check the blower switch but wanted to know where to look for it before I just start pulling things apart...

Checked the motor and it is good. I have swapped relay and resistor. Where is the blower switch located?

Look at the pic below-there's a connector-which is for the blower motor speed controller at no.12 verify the connector to the controller mating surface. If it matches you're on the right track.
