A/C fan issue - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Just started having an odd issue the other day. A/C fan speed will randomly increase/decrease. It's almost like you grab the fan speed control and mess with it periodically. Has nothing to do with engine speed. No changes in cooling, so I doubt anything to do with blend door. I'm thinking first to pull the covers off the controls and clean the electrical connections, but wanted to see if anyone has experienced the same.

It's usually a sign the fan motor is going bad and will need replacing soon. It's located right above the glove box.

Haven’t had it in my Camaro, but several other vehicles I’ve had with similar symptoms have been fixed by changing the blower motor resistor…..generally up under passengers foot well behind glove box

Yup. The fan motor resistor, not the fan, should be the first thing to investigate.
