Cruise control on my 06 HR Ambassador quit working. Cannot find any fuse or CB labelled for the CC circuit, and a search turned up a thread that said there was a fuse near the brake pedal on an 08 Monarch (I believe) but I can't see anything there either. I emailed Monaco service earlier this week to try to get a wiring diagram of my unit, they emailed me back and said to call the parts department - which I tried 4 times but had to hang up after 15-30 minutes on hold, then left a recorded request for a call-back that never came.
Would appreciate any help.

Thanks, Gary

Gary,

Looking at the chassis wiring diagram, I'm not sure that there is a separate fuse for the cruise control. That system is integrated into the smart wheel system. That module gets it's power directly from the ignition switch, and is fused before the ignition switch. If other functions on the smart wheel are working, I'd guess that it's likely not a fuse problem. However if it is a fuse causing the problem, it is likely in one of the two fuse boxes beneath the big box in your front run bay.

The cruise control circuits tie into the smart wheel system via Jumper #3 on the smart wheel control box. Make sure that jumper clip is securely connected. It is a 12-wire harness. (See details here.)

But just a wild thought here, in case you haven't thou gt of it. On 2006 models and before, the cruise control will not set if you have the PAC brake on. Make sure the PAC brake is switched off.

Solved my own problem!!

Thanks for your reply, Robin - I agree, my cruise control circuit does not appear to have it's own fuse. And my unit doesn't have the smart wheel (wish it did) - All controls are in the armrest, and that is where the problem was: The Cruise On/Off switch has a bad contact! It is intermittant on one side of the DPST switch and that prevented the cruise from working.

I was actually in the process of installing the BrakeSwitch - Homer Hawks has been a great help - my Ambassador is not wired like many of the Monaco units he has experience with. We finally got the brakeswitch to work as it is supposed to, then I "lost" the cruise control. Well, between Homer in North Carolina and me in AZ, we determined that the Cruise on/off switch had gone bad, now I just need a new switch and it will be better than ever!

So tomorrow I'll try Northwest RV (or Monaco if I can get an answer in parts) and try to find a new switch.

Gary,

Great! Glad you found the problem. You'll like the way that BrakeSwitch works. On 2006 and earlier coaches it is a GREAT addition. (Don't need one on later coaches.) And you couldn't find a guy who supports his product better than Homer Hawks.
