Cruise Control

[melav]

The Cruise Control on my son's 2000 Boxster S (which has now done 130,000 miles without any problems at all) has stopped working. The green indicator light does not turn on nor can he set the speed control. My initial guess is that a fuse has blown. Can anyone add light to the subject (literally and figuratively). Which fuse should he begin with and what else should I suggest he check.

Fuse assignments Row B 7 Brake lights, cruise control

BTW- check your brake lights before you crawl underneath. They are on the same fuse.

Thanks for the information. The brake lights are working and the fuse is clearly intact. The switch clicks on when pressed in. Any ideas where to look next.

All I can think of is the switch is bad or something wrong with the DME. The fact the switch clicks into position does not mean anything. I thought maybe the indicator bulb could burn out and maybe the cruise control would not work, but I do not know enough about the circuit

Unless someone has a better idea it is time to get hooked up to the dealer's computer so they can see where the fault is. I do not know what more a DIYer could do except pull the steering wheel and check the switch with an ohm meter. And also check the indicator bulb by removing the cluster and opening it up.

Let us know what it turns out to be.

Thanks for the input. I hope that it is not the bulb as this would be a really stupid circuit to design! Anyway, the dealer will have a look and I will post the verdict.

Mel,

I'm having the exact same problem. What was the conclusion?
