NO CRUISE CONTROL
During our last trip June/July 2015, I posted that our cruise control would not lock in. The dash icon light illuminates but the cruise does not work. Now that we are home, I would like some help to repair it.
2007 Fleetwood Discovery 39V with Cat C7.
The cruise operates from the turn signal staff. Since the C/C icon light on the dash illuminates, I don’t suspect a fuse. But, I have not been able to locate a fuse for the C/C.
Freightliner Customer Service states that a fuse was installed by them but Fleetwood would have located it in the coach body. Fleetwood states that the fuse is located somewhere at the driver’s side front of the coach. There are no fuses in the generator compartment or the driver’s side outside storage compartments. The only fuses under the dash are behind the center dash door. None are marked for the C/C.
Does anyone know where the C/C fuse is located for a 2007 Fleetwood Discovery 39V with a Cat C7?
I have also checked the following because of info from this forum or Freightliner:
1. Brake light bulbs & operation: Good
2. Two air operated switches at the base of the brake pedal: Good
3. Turn signal staff wiring harness connections: Good

· There are no solenoids on this model. The C/C functions are electronic.
· The fast idle (cold engine) function of the C/C does not work. But I don’t know if it ever did. I have never used it.

Did youlook at the engine to determine how it controls the throttle,i.e.eletronic or mechanical linkage?

Cat C7 is electronic.

Kuzzy & wrench18 Thank you for your reply . As stated in my original post , the C/C is electronic not mechanical . I am still looking for a fuse location , or if the C/C is equipped with a fuse .

I know you've looked at the two brake switch's at the bottom of the brake treadle, since you said you checked Two air operated switches at the base of the brake pedal.

Is there any chance there is a small amount of corrosion on one of these switches?

There have been reported cases of corrosion providing enough voltage to kick off the cruise control without affecting the operation of the brake lights.

"Furniss"....I was a Monaco guy with a Roadmaster chassis up until last year when I bought my first Freightliner, so I'm not as familiar with Freightliners as I was with Roadmaster.

On my 2014 Freightliner, the fuses you're looking for are in the right rear compartment where my start batteries are located. There is a small box with fuses. Take a look around your starting batteries.
