Chk the fan speed resistors mounted in the fan housing. You should be able to see the wires going into the box with 2 screws holding the resistors in place. Good Luck.

There is a blower resistor that can fail. it's behind the glove box by the blower motor. there is also an auxiliary blower motor resistor in the back. if i had to guess i would check the front one first. you have to open the glove box then reach in the back and pull it all the way out. then you have to remove what gm calls the plenum tray. then there is an electrical connection that you have to unplug and then take the mounting screws out and then put it all back together. it is a good practice for safety to disconnect the battery negative terminal while you do this. hope that helps

Rear ac blowing hot


How does front AC blow? Make sure temp controller for back is set to cold.
You might just need to have your AC serviced.
