I've been trying to revive the cruise control on my '82 911SC. I've been through the Bentley diagnostics, the clutch switch has been cleaned, adjusted, and activates the relay, and the last thing I did was test the servo with 6v across sockets 3 & 7 and the engine accelerates, so that tests OK! After all the diagnostics, I plugged-in the cruise control module. Took a test drive and the cruise is still inop, but when I attempt to engage it, the brake warning light on the dash comes on! (The same light the parking brake triggers). My brakes are fine, fluids good, incandescent filament brake lights, and no problems prior to plugging in the module! I reset the light by disconnecting/reconnecting the battery with the ignition "on." When I removed the module and reset the light, it stayed off.

I know that the cruise control module (928.617.127.00) is the usual source of most inop cruise problems and likely is the source of this problem, but I've never heard of the module triggering the brake warning light. My module is used but not "known good." It has a warranty so I suspect I'll be getting another module to try. .

Just thought I'd run this by the forum while I wait on another module in case there is something else I should check! Alternatively, I may just send the used module out for repair so I'll know I'm working with a "known good" module.

For repairs, I've seen Kris Rose (cruisecontrolrepair.com) highly recommended and relatively inexpensive. His website seems only partially enabled and although he mentions to email him, nothing is listed under "contact." I found elsewhere his email is "JamesDean59@gmail.com." Just emailed yesterday and haven't heard back ... is he still in business?

I've also seen ASI (autoecu.com), George Murphy at Performance Analysis Co (perfanalysis.com), "mandigital" on Ebay, and Beckman's recommended. Any recommendations or any that should be avoided?

Thanks,
John
