2010 Chevrolet HHR - cruise control fix

what could i be changing out to repair the non functioning cruise control on a chevy HHR? on/off light works, but the engage button seems to do nothing

I’d start by testing the engage switch with an ohmmeter. Does it open and close the circuit?

Beware of airbag safety procedures when working on/near the steering wheel!

A bad clock spring can cause the cruise not to work.


Additionally, burned-out brake lights or a bad brake light switch can result in non-functioning Cruise Control.

Check the 3rd (center) brake light. It’s an easy one to miss.
