Default Heater module

I can’t get my heater fan to come on. I have power to the red wire on the heater module but I don’t have no power on the purple wire. How do I get power to it?

help us out here. What year is the car, and since it's HVAC related, which HVAC control do you have?

C68 Automatic cliamte control or C60 with Manual controls?

It’s a 1990 C4 I have replaced everything on it to a new fan motor. Then I found out the purple wire does not have no power to it coming from the plug on the module that’s on the firewall

It has the push buttons climate control inside the car it gives you the outside reading of the temperature on the face. I guess that’s what your calling HVAC? I even changed that thinking it had something to do with the problem.
