Cruise control

[Jim Keaty]

I just finished replacing the engine in my 345 classic. I went with the recommendation of my mechanic and replaced it with the same engine that was in it originally. My cruise control is not working and my mechanic is having a hard time finding the right cruise control to work with my system. Does anyone have any recommendations or know where I might be able to find a cruise control system comparable with the 1988 345 airstream Motorhome?

We have also been having issues with my break lights and blinkers at night. At night the break lights and blinkers are very faint compared to my running lights so it's hard to see the break lights and blinkers. I was told this might be related to the cruise control. Any suggestions?

Older cruise control systems got their throttle servo ground from the hot side of the brake light circuit. It's. Safety feature that makes sure it disengages when you hit the brakes. If your control box has failed, it could be putting a load to ground on the brake light circuit and dimming the lights. Disconnect the cruise control box and servo connectors and see if it helps with the lights. The older analog cruise controls were made by Dana, and I suspect you will be out of luck finding a new or rebuilt replacement for something that old.

Installed one on a 1970 GMC van conversion I built. Loved it when it worked right (most of the time) discovered burned out brake lights made it malfunction. Hence the troubleshooting ideas above.

Thanks for the advise. Do you have any ideas on finding a new cruise control system? Can I have the original one rebuilt?
One of the things that I noticed just before the cruise control went completley out was it would work when I was pulling a trailer so I thought it was just a ground issue but we could not find any ground issue. I took it on a trip and it worked for about 300 miles but not its completely dead.

Sorry, no clue on rebuilds. All my cruise controls are factory and integrated into newish vehicles. The old van is long gone, but not forgotten...😄
