Heater Fan won't shut off?

Postby fas141 » Sat Oct 08, 2022 6:03 pm

77 Monza, no AC car. The fan works on low-med-high but won't shut off? Is it controlled by the heat switch moved over to the off position? Thanks for help.

The fan is part of the car's ventilation system, it stays on all of the time the ignition is on.

Yes, it is designed to run on low speed as long as the ignition is on. If you want to stop it from running you can pull the "low" wire off the fan switch. You will of course only have medium and high.

I'm glad I'm not the only one wondering about this :lol: I'm in the process of hooking up my heater for the first time since the V8 went in 12 years ago and I spent a long time sorting wiring only to look at the service manual and confirm, yes this always runs. Great timing for this question :D
