CRUISE CONTROL

2004 Ford Explorer

Electrical problem
2004 Ford Explorer 6 cyl Two Wheel Drive Automatic 69000 miles

I'm having trouble with my 2004 ford explorer's cruise control.
Two or three months ago the c. Control light would not come on and I had no cruise control. I would tap the brakes, push the 'on' button and 'set' button of the c. Control and it would come back on. Every now and then the ABS light would come on. When I would stop the vehicle and turn it off and later turn it back on the ABS light would be off and the c. Control would be out again. For the last two weeks the c. Control goes off most of the time and I have to tap the brakes even more to get it back on. Now, even tapping the brakes does not bring back the c. Control. At least the ABS light is not on now. Do I have a sensor or connection problem?

Do you have brake lights? If yes check the brake pressure switch on the master cyl...install a jumer between the contacts, just as a test! Cruise may not deactivate with brake application! Use switch! If no brake lights, check switch on brake pedal arm...it's the brake pedal position switch...

I found the break pressure switch on the master cyl and unplugged it. Could you show me what the jumper looks like so I can get one to test.
Also, how to test with it.
Will this cause a short in the wiring?

Thanks

Just use any small piece of wire in the connector end. Plug into both wires.

After I plug the wires into both holes of the plug what I'm I looking for to show whats wrong with my cruise control?

Go for a test drive to see if by jumping out the switch, does the cruise control work? Be careful, it won't turn off with brakes this way. Hit the off switch.

I did as you said with the wire, but the c. Control did not come on. Never the less, I enjoyed testing it the way you showed me. I felt useful. To bad it didn't work.
I guess the problem is somewhere else. Do you have any idea what it could be?

Thanks,

Maybe I did not have the correct testing wire. I read where it could be a sensor located at the rear of the car.(Differencial?) Can you help?

My advice to you is replace that deactivation switch, bleed the master when done, and dont spill the fluid on the paint!
