My A/C in the front works fine but not getting any power to the back A/C blower motor. I checked all fuses and they are good any suggestions on what I should look at next? Any body know what's the problem?

Hello, I'm Danny.

It sounds like you may be having an issue with the rear A/C/heat aux blower motor resistor. Chevrolet trucks and SUV's have had this problem for years. Check to see also if the resistor wiring harness plug is burnt or melted. Pretty common as well. Most auto parts stores have a replacement harness with connector. I've attached picture instructions below. Hope this helps and thanks for using 2CarPros.

Hello again.

I've attached a picture below of the different systems for your truck. Can you let me know which you have and we'll go from there? Thanks again for using 2CarPros.
