My cruise control started taking breaks every so often on Thursday and continues to do so. It works fine when it works but will cut out and not work for 30 seconds to 30 minutes and then work again. If I turn it off or tap the brakes it quits like it should but then won't come on again. I thought about the brake light switch but I was pulling a trailer and the trailer brakes never came on when it quit working. Never had this problem before so I'm clueless, any ideas?

One possibility is the Variable Speed Sensor (VSS) located on the rear differential. About a $25 part IIRC and easy to change. Just one thing to look into...

Easy, there, Ryan! Let's not send this fellow on a wild goose chase! /ubbthreads/images/graemlins/rolleyes.gif

I am having the exact same problem as this guy right now!!!

There are <font color="red">NINE DIFFERENT FACTORS</font> that need to be favorable in order for your cruise control to work. /ubbthreads/images/graemlins/mad.gif Ford and their 'better ideas.' /ubbthreads/images/graemlins/smirk.gif
Don't do what I did, and start changing likely suspects because DieselStop members have told you what fixed their cruise control. /ubbthreads/images/graemlins/shocked.gif

Failure of the following components will cause your cruise control to stop working:

1) Brake light bulbs
2) Brake pedal switch
3) Brake booster pressure switch
4) Parking brake switch
5) Clutch switch
6) Cruise control switches
7) Clock Spring
8) VSS
9) PCM or GEM, depending on year

The first action you should take is to check your brake lights, and replace any burned-out bulbs. Do a quick and easy check of some basic parameters: Check that your brake pedal switch works. Check that your parking brake instrument cluster lamp works when the key is first turned on, and that that warning light isn't on unless your parking brake is set. Watch your Airbag light, and see if it stays on for more than 3 or 4 seconds after starting, or if it flickers on and off randomly.

The second action you should take is to perform a scan for codes with a scan tool capable of initiating your PCM's self-tests. Auto Enginuity is one, I used a friend's Snap-On unit.

Don't do what I did, and start changing parts before you truly know what's going on. /ubbthreads/images/graemlins/eek.gif

I didn't mean to suggest that that was the fix, just listing one possibility. /ubbthreads/images/graemlins/warmsmile.gif

I should've just pointed him to your thread! /ubbthreads/images/graemlins/wink.gif It's got some good info.

Does your work now ?fixed?

 

[DarthSurplus]

Nope. /ubbthreads/images/graemlins/frown.gif

New clutch switch goes in on Saturday. Look for an update then. /ubbthreads/images/graemlins/smile.gif

Mine was the clutch position switch.

 

[GreyHorse]

Ok, thanks guys, looks like it isn't real easy to track down the problem...... especially since mine works sometimes. Sounds like I may have a weekend project on my hands.

 

[DarthSurplus]

Success!

I have fixed my cruise control.

It was the clutch switch.

I certainly wish I had scanned for codes first.
