    Hey guys, I can't figure out why my cruise control won't work. I'll go over what was recently changed in my car. In the last two months my water pump, thermostat, radiator, lower radiator hose, spark plugs, spark plug cables, the distributor? The part that the spark plug cables hook up to. I'm too tired to google it.

    My car is a 2000 Ford Escort ZX2 2.0L Zetec engine.

    Now, previous modifications to the car that might be of help, timing belt replacement, power steering belt replacement two times, fuel filter, fuel pump system. I don't remember everything else at the moment. Also my new radiator is 1/4th an inch smaller in core depth, was experiencing a lot of heating issues until the distributor or whatnot was changed. The other change that was not able to be observed until after the distributor was changed is a hole drilled into my thermostat to add more water flow. Also, one other factor that might lead everyone to say a wiring issue is at the end of the last year, I backed into a tree hard, and my engine fuse blew and I had to up it from a 15 to a 30 for it to not blow. But cruise control has worked until the recent work on my car. Mainly since the work with the spark plugs, spark plug cables and the distributor.

    So, what do you all think? If you need more info, just ask questions and I'll answer.

    old post but the answer is probably the rubber stoppers for the brake pedal and/or clutch pedals. These stoppers are at the upper part of the pedal arm and contact the switches. If these come out (usually because of age) the switch will think the pedal is being pressed and will deactivate the cruise control

    I'm also having issues with my CC having stopped working. Does anyone have a picture of the bumpers? It's hard to get in there and see what it is you're talking about.

    AHA! I think we're on to something here. I remember seeing one of those on the floor board and wasn't sure what it was for.

    Looking under the dash I find two switches that are acuated by the brake pedal. I tried to do the bottle cap trick on the grey and black switch but all it did was depress the brake a little and when I drove it it felt like I was driving with the emergency brake on. The switch with the blue body looks like it controls the rear brake lights. Am I wrong? Where do these rubber stoppers attach to? It's hard to get in there but I assume that they go on the metal stop pad behind the switch or does each switch have a rubber bumper? I didn't see a hole for the rubber post to go through but if that is where they go I would assume there will be a hole behind there for them to pull through?

    There should be a hole they go into. It may be covered by the moving part of the brake and cruise switches.

    Does each switch get a rubber stopper? When I put a bottle cap on the white and black switch it seemed to have applied a little brake and it felt like the emergency brake was on. Judging from the thickness of the rubber stops it seems like it would do the same thing.

    Can you tell me which switch pertains to the cruise control and which to the brake lights? I'm guessing the cruise control switch is the one with the blue body.

    I think the brake switch is the one on the right, or the one closer to passenger side. Will have to check my car. Both should have a bumper

    Sweet! Thanks for your help. I'll get some bumpers and see if that does the trick.

    One thing, as I mentioned prior, when I stuck bottle cap on one of the switches it seemed to depress the brake a little and I could feel the brakes dragging. Will I need to readjust the pedal rod to compensate for the width the rubber bumper adds in case that happens?

    EXCELLENT! I guess the best thing to do would be to pull off the switches, install the bumpers then reinstall and readjust?

    Another option to replacing the rubber bumpers that are eventually going to crack again and break into pieces on the floor mat is stick magnets to the metal in their place. The bumper broke on my '02 several years ago, I used neodymium magnets 1/8' thick x about 1/2" diameter. All you want is enough thickness to close the switch when the brake pedal is released to turn off the brake lights and let the c/c know the brake is not applied. I've also heard of people epoxying 2 pennies together then epoxying them in place. The best remedy for this would have been if Ford had made the plunger of the switch 1/8' longer then there would have been no need for the bumper. I simply pushed the brake pedal enough to allow me to get my fingers in there to put the magnets on, no need to remove the switch. The magnets haven't moved in several years use and I don't have to worry about them breaking and falling out.

    Great idea! One issue I have is I read on here someone used a plastic bottle cap to replace the bumper which I tried on the switch without the plunger. What happened was it pushed the brake pedal down slightly which was just enough for the brakes to drag. Almost like having the emergency brake on. I noticed it has two lock nuts. Do I need to readjust this once I install the magnets so that the brakes don't drag? I'm going to assume that the switch with the plunger is the one that controls the CC?

    curious, is this the same case for say.. a '92 EGT? my CC is a fail and I've gone through several electrical avenues to diagnose the issue.

    I didn't have to do anything to the switches on my '02. If you use a magnet 1/8" thick I don't think you'll need to adjust anything as the rubber bumper if I recall correctly is at least 1/8" thick. The switch with the plunger would control brake lights off/on and also affect the function of the c/c. If the switch isn't closed the brake lights stay on and sends a signal to the c/c that the brake is being applied.

    Did the bottlecap trick to the plunger style switch and I now have CC!!! This is temporary and I'm going to do as you suggested with the magnet.

    I'm pretty sure there was a warning light in the gauge pod signifying when it's on or not and it's not working. I have to get in there and replace some of the cheap EBAY LED's that failed so I'll try and see if there is a CC warning light and make sure it lights up when CC is on.

    I have a question about the other switch. It has a threaded bar with two lock nuts. What does this do? It doesn't have a bumper either but doesn't seem to be affecting the car in any way that I can tell.

    Thanks again for all your help!!

    My Ford Shop Manual describes one as the BPP (Brake Pedal Position) switch. The other one as the Deactivator Switch (for cruise control).

    Can you point out which is which in the photo I posted? Blue bodied switch has the plunger while the grey bodied switch has the threaded rod and lock nuts.

    John, I'm guessing the cruise control switch is the one with the blue body. Was 2010 when the plastic bumper fell apart on my 2000 SE and brake lights were on all the time.

    Thanks so much to you and everyone for putting up with all my questions. I'm going to head over to HF tomorrow to pick up the magnets. Is there a warning light in the gauge pod that tells you when the CC is engaged? The right side of my gauge pod bulbs have stopped working so I need to get in there and replace them. Just want to make sure I get everything that needs a bulb.
