Cruise Control not working

for the past year or so there were times my cc wouldnt work but would work after driving for an hour. well the for the past 3 weeks my cc hasnt worked at all and i was just wondering where i should start. ive already cleaned the switches but i havent had time to do any continuity tests on them yet. im hopefully gunna try to get to it this weekend. thanks for any input - Chris

Check, third brake light, underhood fuses, multifunction switch on column, and wiring in the steering column.

:whs:

will do. Thanks!!

Also check the VSS (vehicle speed sensor) on top of the rear axle housing.

MIne done this ended up the pressure sensor on the master cylinder was shorting out because it was leaking fluid out and it ate the coating off the wires. It blew one of the fuses in the engine compartment fuse box finallly and quit working all together also it made my backup lights quit working. I guess this is a problem for ford according to my ford dealer. They got an updated part out for it and it runs like $17 I put it on and it fixed the problems.

This sensor i believe is on recall due to it can cause a fire. (some years)
The update sensor is red IICR.

Bill

Recall was SD.

Bill

I thought the recall covered all vehicles without a diesel?

they told me to keep my receipt on the part incase ford recalls it or something like that. But yeah the new part is totally different.

none of the fuses are blown so when i get a chance ill start looking deeper for the problem. Thanks again, Chris

its your clock spring. 60 bucks form advanced auto

I'm in the same boat. my cc dont work either

Make sure to check the 3rd brake light.

change your clockspring

what is the clock spring

its a coil of "wire" in the steering wheel that allows the controls to still function while the wheel can still turn.

its basically a coil of wire, and as it starts to wear out, your controls will intermitintly work untill one day the contact is gone. thats when you loose all your steering wheel functions. does your horn still work?

I would like to have the part number for that new sensor. That is the fire causing part.

Tom

Yes horn blows But the driver dont so do ask that. lol

lol dont worry, i wont ask

does the lights on the cruise control buttons work? at first just my cruise control would work when it wanted to, then i had to honk my horn to set it, then it all stoppe working.

My lights I dont think have ever worked. I know the coast button has always be flakey. But the cruise has always set fine. where do I get this coil and how hard is it to change?

advanced auto. you need a steering wheel puller, BUT the one i used messed up my steering wheel. i then tried an ac clutch puller, worked perfectly. thats the only "special tool" you will need, the rest is basic tools

Guess I will check that out in the next couple of days

I had the same problem as Speedy but there were no blown fuses...Just enough liquid in it to trip the connection some how. Either way, got it replaced and I haven't had a problem since. Might wanna make sure that's it before you start replacing the more expensive parts....I learned the hard way.

ok just realized this is an obs thread, i dunno how yalls trucks work compard to mine. so see what happens with everything else first

Check that sensor on the master cylinder if its wet thats most likely the problem

I tryed jumping that plug and it still didnt work.

which sensor is it on the master cylinder?

which sensor is it on the master cylinder?

Its the pressure switch out on the end/ top of master cylinder there is a two wire plug on it.

I have had 2 problems with my cc.The first was the brake switch.It was shorted just enough to kill my cc and flicker the brake lights once in a while.The 2nd which was similar to yours ended up being a broken tab holding the neutral safety switch in to the right of the clutch pedal.It had come loose and because I had bypassed the starting part long ago it took awhile to find the problem.

TERRCO- so all you did was fix the tab and it worked, or did you have to replace something? Just curious because I've also by passed the nuetral start switch.

My backup lights arent working either could that have anything to do with it? I just try and find that problem tomorrow.

Hey JD 9610 my backup lights quit working once that pressure sensor shorted out I guess its on same fuse as the backup lights. Dont recall it being listed on the cover as on that fuse but it was.

I check all fuses and they are good. I used a meter on everyone so I know they are good. how does that pressure switch work? normal open or closed trying to check it with a meter.

I'm not sure mine was just leaking fluid bad raound the top and the plug and when I replaed the blown fuse i seen small smoke and sizzle on the plug area right before it blowed the fuse. Is you pressure switch leaking fluid if not then you may have a different problem. Good Luck.

pressure switch is dry. changed the transmission range sel. On the side of the tranny and It didnt fix a thing. So now I'm way in the dark on this. No back up lights or cruise. I dont know if they are linked or not.

:shrug: Don't no man.

I would like to have the part number for that new sensor. That is the fire causing part.

yes thank you - chris

I did some reading on this subject and it looks like the fire issue recall only applies to the gasser trucks.

Tom

Stroked95 I should have replaced the pigtail there but I just put a ziptie for now and its been ok.The plug was workin itself loose.

Well mine still dont work and its making me made to say the least.

I Never could get it to work in my '94 so I gave up since I've got 2 other trucks that it works in.

-Michael

well I have a 700 mile trip coming up I would really like to try it.

did you check the fuses? could also be a relay.

havent check relays how would you go about that? all fuses are good
