I lost my cruise control and do not see any blown fuses. does anyone know what might have happened. this is on a 1996 F150 stright 6cl manual.

 

There's an electrical connector on the master cylider I beleive, pull it and if you see any brake fluid replace the M.C.

 

Does the horn work?

 

Also is your air bag light flashing? If so your clock spring has a bad spot in it. Many people have this problem our year trucks. Its not all that bad to fix.

 

My horn works and there are no lights flashing. I will check the MC

 

If there is fluid in the pressure switch, replace the switch not the Master cylinder. The switch is around $25 to replace and is the subject of recall (fires) on later F150's.
Switch needs to be closed to allow cruise to work, when it opens with MC pressure cruise is deactivated.

 

thank you for your help and I hope we can fix this

 

ok I located the switch and it stays closed until the brake is pressed and then it reads open. should I look at the switch in the stearing wheel?

 

Also Is there a relay in my fuse panel in the engine compartment that controls this?

 

There is a switch on the brake pedal, mechanical and one on the clutch, mechanical. I believe both of these shut down cruise when respective pedal is depressed Check both to be sure they are nor broken/misadjusted; brake switch is closed with pedal depressed, clutch switch closes when depressed (two sets of contacts one to start and one for cruise).
Check fuses 13, 18 and E

 

ok I am stumped I checked the fuses under the hood and in the dash they were fine I did not find a fuse labled E. I also did not find a switch on my clutch pedal but the one on the brake is working alright. HELP!

 

Hello,

My name is Freek from the Netherlands Europe.

I have the same problem.

I've replaced the clock-spring, but the cruise-control don't work.
Horn and fuses are OK.

But the mastercylinder is leaking.



So this should be the problem ?

Witch part must be replaced ?

The red one ?

Thanx in advange,

Freek

Freek - disconnect the connector from the pressure switch until you get a replacement. This switch will prevent the cruise from working - it also has power to the switch at all times. Do not leave the power on the leaking switch.
dehman - I am looking at a 95 manual so do not have all the right info for 96 model; check your owners manual for fuse locations applications and numbering/lettering. on 95 numbered fuses are in instrument panel fuse box and lettered fuses are in engine compartment fuses panel. On the clutch I would think there would be some device to disengage the cruise when the pedal is depressed to prevent overrevving the engine, the 95 manual shows a mechanical switch on clutch pedal linkage in passenger compartment?? Look for something on clutch circuit, Hydraulic clutch?? pressure switch??
Other than this, the clockspring, cruise servo, PSOM and PCM (and all associated wiring) are all involved, but with the differences noted between 95 and 96 you may need to find newer info source for your application.
I did have to take the cruise servo cover off and clean up corrosion on the interior and free up the mechanical components (search for cruise control in forum and you should come up with several threads with details).

 

Thanks for the reply.


I've disconnected the connector.

I've ordered a new switch.
But (as usual) it takes a while at the other side of the ocean.
