Cruise Control not working

I did the diagnosis,on my non working cruise control on my 2000 f250.
The cruise light came on when, I, depressed the off switch and turned key on.
I depressed on switch,cruise light came on.
I then depressed the resume, coast, and set switch, as described in the diagnostic procedure,suggested,and no light came on.
Does anyone,have an idea if the swtiches for the cruise control are bad.
I have checked the fuses at the power distribution box under the hood and checked the fuses under dash,all are fine.
I just replaced the switch at master cylinder,as it was leaking and it had the recall switch replacement,too.
Thanks,
Steve

Bypass the recall harness and switch on the master cylinder for testing. If the switch was leaking, it likely blew the fuse in the recall harness.

remove the recalled fusible link harness, then try your cruise control again.

Sorry, didnt mean to repeat what you posted.
But, this just happen to me, my cruise control went out about 3 weeks ago. And my brake pressure switch wasn't leaking. So, I removed the recall fusible link, put a meter on it and showed an open circuit. I connected plug from Harness to brake pressure switch. Then, took the truck out on the highway and performed an ops check on the cruise control and it check out good, cruise control was working again.

I still haven't decided if I should get a new fusible link from the dealer or just buy a new switch. I'm the third owner of the truck and have no history of recalls performed.

buy a fuse. Take truck to dealer and they will check recalls and preform them as needed

Bluegrass 7 has a very good reputation on FTE.Bluegrass 7 has a very good reputation on FTE.Bluegrass 7 has a very good reputation on FTE.Bluegrass 7 has a very good reputation on FTE.
The next step is to know how the circuit is powered and it's knock-off operation.
1. The master cylinder pressure switch powers the control unit.
when the pressure rises above the switch opening point the 12 volt power is removed.
2. At the same time, the brake switch 'applies' power to inhibit the controller.
Both together or singally will stop cruise control and release the cable drive to the throttle.
My experience based on your report is the pressure switch circuit may be open.
The test is to use an ohm meter on the pressure switch to test for an open condition and voltmeter test to be sure 12 volts is present on the controller side of the switch.
It is possible that an after market switch in not made to spec and opens at to low a system pressure especially after the engine bay gets hot and the fluid expands causing the switch to go open. 'Be sure to test when you know the system does not work.
Be sure to consider the brake off normal switch as being shorted applying an inhibit signal full time.
A simple test for the fuse assembly is to remove it and plug the power connector directly onto the pressure switch and re-test.
.
With power issues the system 'cannot self test' without power and give you any codes.
The controller seldom ever goes into trouble so be sure before placing it.
Good luck.

Hey guys,

my cruise control doesnt work neither. light will not go on, changed steering wheel button already since the button was hard to press before it let go and this didn't fix the problem. as for the rest of the thread, its for older fords, I have a 2011 F250 Super Duty.
my brake switch has 4 pins and brake light, horn... works and no lights in the dash indicating a code.

does anyone have the schematics or anything on the brake switch or cruise control system?

Thanks for the help in advance.

Cruise control and horn not working

Need some help. 02 Ford F250 V10 cruise control not working. No lights on the dash or the steering wheel and the horn fuse keeps blowing the second I install a new one. I'm leaning towards the clock spring but I was wondering if it could be anything else. Any ideas? Thanks

Sorry about that, It's fuse # 37 Horn. The second I put a fuse in it blows, then I noticed my cruise control doesn't work at all. I don't have a cruise control light on the dash or an air bag light when the truck is running. When I turn my headlights on I noticed that the actual buttons on the steering wheel do not light up either. I keep reading about the clock spring being bad. The truck has the factory alarm and the horn doesn't chirp when I alarm it either.

You'd either have to have a wiring fault or else two different simultaneous failures for that to happen like that.

If F37 is blown, the horn will never blow. The fuse, by itself, has no interaction with the speed control system.

Pull the horn relay and see what happens with the fuse.
