Cruise control intermittent failure?

[Nick]

My CC stopped working when I serviced the breaks and drained - replaced all the break fluid.

My swith points down, 06 E350 DSL 6.0, is there a way of replacing the break deacgivation without having to drain the master cylinder ?

I read somewhere that you can remove the switch and fluid won't drain out. I haven't done it yet although I've had a new switch in my garage for a few months. I just used a paper clip to jump the switch and I've been using it like that for a while.

MKRacer is correct in how or if to do this. Even though I have the new parts now my E250 seemed to develop this fault during its first for me road trip. I had tools on board to wire a jumper into that circuit and its been in place ever since. Lazy I am at times...........

Removing the actual switch can be done without draining or otherwise disturbing the master cylinder. Have a few rags ready or laid under the m/c to catch the small amount of fluid that might drain out. Keep the new switch in hand and ready to put into place as the old one is removed to lessen any leaks. Most likely you'll have less than a tea spoon worth anyway.

Check and re-fill the reservoir as needed, reconnect the wiring harness connector and you're done.

Thanks, any chance any of you know the part number for the switch for an 06 DSL 6.0

I've already posted that info just one page back.

Changed the pressure switch from the break oil canister and all my intermittent problems are gone, system working like it should and the old pressure swith had a rusty looking color. And, as indicated, did not have to drain the break fluid, in all a 15 min job.

Thank everyone !

I'm going to try as well since the CC has been intermittent since the day I bought my van. Very annoying on long trips!

Beer's on me if this actually fixes the problem.

I've had to replace at least 3 in different vans with intermittent problems. When it didn't work at all it was the "Clock Spring" but then the horn didn't work either.

I had a problem with cruise control on our 2001 many years ago but I don't remember exactly the problem. Ford fixed it and said that the wire inside the cruise control "arm"(?) shorted out. They said is was a fairly common problem.
