The Cruise Control on my 2002 Forester S stopped working recently. For some time I had problems engaging the CC altogether, requiring multiple clicks on the activation push-button. Then it stopped working completely.
On a retrospect, I may have confused a possibly-bad CC (on-wheel) lever with the button.
Anyway, the green and amber bulbs of the button died some time ago, and I thought maybe the burnt bulb opens the circuit, so it cannot be engaged. Searching for replacement reference, I found replacement bulbs at RadioShack, and this week I finally had the time to replace the bulbs on the CC switch, and on the way, the wipers de-icer.
Unfortunately, replacing the bulbs did not solve the problem, and the CC does not engage. How can I troubleshoot the problem source? How do I know if this is the lever, wiring or the module itself (whatever this one may be)?
