I have been having an issue when the AC is on, and the fan is blowing the fan will intermittently turn on and off. Keep in mind the AC Controls to not turn off or adjust or anything. Just the fan starts and stops. When it is not blowing, I can still feel a small amount of cold air coming out. Instrament control panel has no issues. When it is running it does respond to the fan up/down and adjust accordingly.
The auto system uses a pulse width modulated (PWM) signal on the “module” instead a series of resistors to control blower speed…could be a bad module or motor or even a wiring issue.

appreciate that. I started with changing out the blower motor itself but didn’t solve the problem.
Just wanted to update everyone. It ended up being the blower motor resistor. I went ahead and changed the blower motor as well since I had it tore apart already.
