The button that turns on the A/C is not working neither is the nob that controls where the air goes. A wiring diagram would help.

Hi,

I attached the wiring schematic for the entire HVAC system. I'm assuming this is a full-size truck but need confirmation. They used the same engine in the Dakota.

Let me know. Also, the schematic below is two pages. I had to cut each one in half to make them readable for you. I did overlap them so you can follow from one to the next.

Here is a link you may find helpful:

Let me know if this helps and if I got the correct model.

Take care,

Joe
