Is it the control head assembly in the dash or is it the blower module/resistor assembly? Is it in this picture?

I don't see the module. Are you saying it is in the dash?

Expert:  Gary replied 6 years ago.

I was asking if it is the module control assembly. It’s the control that you actually push the buttons on or the resistor/blower which is in the other picture. More than likely that’s what you are replacing. It is located under the passenger side of dash and very simple to change. Remove the little plastic insulator under the passenger side of dash and it is located right next to the blower motor.

I believe I need to replace to module. I have little to no air movement in AC or Heat, but the blower stays on after turning off the key. The battery is run down in the AM. Based on other reports, the module or the resistor is to blame. Are they both located under the passenger side dash?

Expert:  Gary replied 6 years ago.

Yes and the resistor and the blower module are one piece or I should say incorporated into one unit. Change it just how I said to in last post. It’s very easy to change out.
