Cruise control

[Jean-Marc Dugas]

My to-do list for the summer includes getting the cruise control to work in my ambulance.

For this I will need a replacement cruise control switch and possibly a refurbished Transducer.

Before I scavenge eBay for parts, I figured I would start here. Would anyone have any of these 2 iterms available?

The car is a 1976 Cafdillac Commercial chassis.

The switches rarely go bad and the best thing to do is to take it out and test it. There is also an electrical switch and a vacuum switch at the brake pedal if either one is defective or there is a vacuum leak the system will not work. Most times they don't work it is because of a vacuum leak. Another place where vacuum leaks are common is the neutral safety switch and the brake release switch. Should your switch be defective try to find a NOS switch since the "rebuilt" switches don't hold up well over time.

I echo what Paul said. If you brake pull off works you know the safty switch is not leaking. But that is a weak spot in the system forgotten by most. A number of vacuum lines and plastic Ts to brake and leak. I don't think i have ever seen a bad on off switch.
