No Cruise

Ford or Chevy?

Sorry... Ford

make sure your brake lights are not on. a hung or defective brake light switch will cancel your cruise control.

The cruise control circuits are often routed through or depend on brake light switches to operate. This means that if the brake light switch is on continuously or malfunctioning the cruise control believes it should be turned off.

Brake switch. These folks are right. Ford or chevy. The brake switch is the first and easiest problem to solve.

Vacuum leak affects some cruise controls. Not sure about Fords.

Brake Light switch is possibility. I've had this happen on three different vehicles.

One the brake light switch vibrated out of adjustment so the brake lights were always on

On Two the brake light switch died.

my 1999 winnebago chieftain would have the cruise go off, and the odometer/speedometer stop working with a CVsensor or some such went bad. some small $8 gadget that I think stuck in the transmission.

Ford did NOT make a 1998 F53 chassis. Your coach is either on a 97 460 chassis or a 99 V10 chassis. Big difference in trouble shooting a chassis electrical problem. One little quirk I discovered about Ford cruse control is, LED tail light bulbs will sometimes keep the cruse from working. So have a look at the bulbs. With LED tail/stop lights a small pull down resistor is some time necessary between the stop/turn wire and ground.

the 1998 unit probably was built on the old ford chassis with 16 inch tires. I ordered my 1999 as soon as the improved chassis came out.
I have seen newer model years built on old chassis but never the reverse. My bounder and my Glaval Halfback conversion van were given the new year designation.
