Our cruise control stopped working on our F53 frame MH. It has the ford v-10 engine.

Any ideas what I can check?

All advice appreciated.

There are a lot of posibilities.
First the CC uses vacuum so if you have a vacuum leak in the right place. NO CC.
I had a bent pin on a connection.
Blown fuse (it uses 12 volt as well) other bad connection

Bad brake light switch. Have someone stand behind the RV and see if the brake lights are on full time.

Also blown brake light fuse/burned out bulbs. Have partner make sure they come on when you push the pedal

NOTE that last is my #1 suspect.

On edit. a bad GROUND on the brake lights will do it too. But not consistantly(IE when headlights on no CC.. lights off it works).


Home was where I park it. but alas the.

You are WRONG AGAIN........V10 F53s do NOT use vacuum.

The switch on the master cylinder is a not uncommon CC failure point.

OP here.

We are part timers, and last outing was in January, and it worked fine.

However, the windshield washer pump failed, which I replaced, and now works.

Don't know if there's anything in that area of the motor that I might have disturbed.

Also, this is a 2014 Tiffin Allegro gasser.

Thanks guys.

I'm not familiar with where exactly the WW pump is in relation to the master cylinder or other parts are located, but logically it makes sense that the two could be related if the CC failed immediately after you did the work. As was mentioned earlier, there are no vacuum lines or any type of mechanical linkage that operate your cruise control. Ford has used a drive by wire system for several years, so there is no mechanical connection between your foot and the engine. A possible failure point is a faulty speed sensor, but when that happened to me in a different model Ford motorhome, I also got an ABS warning light.

OP here.

Dutch was right on the mark.

I YOU-TUBED that CC switch on the master cylinder, and saw where this has been a problem on many Ford trucks. I found it on Amazon for about $38.00.

Mine was actually on a line below the MC, and very easy to change out.

Everything works as it should, now.

Thanks to all for your responses.
