Cruise Control Servo

[tbone]

My cruise control works intermittently again. I replaced the servo about a year ago, fixed it, but now it is doing exactly the same thing. I replaced the steering wheel switches purely for cosmetic reasons, but I was also hoping it would take care of the problem. I also sprayed the connector with WD-40. I figure I need another used servo. Anyone have a similar experience with this or is there something else to look for?

Thanks.

Define stop working.
Does it shut off and then work right away?
Or does it stay off for lengths of time?

Id look at the switch on the brake pedal before I did anything.

It works, then I turn it off. Try again, no work. Works, no work, etc. It doesn't just stop working while engaged.

I checked the pedal linkages last time before I ordered the first servo. All seemed in order.

I had the same issue on my Town Car. New servo solved it. These things must be pretty unreliable.

I had issues with mine being hit and miss after I had Curless pedal gear fix done, just had to bend the de-activate metal bar piece on the brake pedal arm some to let the system engage and not thinking the brakes were being applied just a hair.

Good advice. I checked on that thoroughly last time. Seemed ok. Then this servo lasted a year before problems again.

I found a new/used servo from an 04 Crown Vic with only 43k miles for $45 + shipping on ebay. Snapped it up. I painted the last one satin black and it looked awesome. Time to get the paint out again.

Almost forgot that I have to do the adjustable pedal gear this spring. Thanks for reminding me.

My money is on a clock spring. First my volume button was hit or miss, then the cruise, finally the cruise just died completely. Did it start acting up after your header install?

Give you steering wheel a slight jerk left or right while you engage it, very slight is all that's needed. That's how mine would activate.

Interesting. I'll try it.

Didn't work. Cruise was dead on the way home from work again.

When doing the brass pedal gear, if the pedal mounted deactivator switch is installed BEFORE the linkage is put on from the brake booster the pedal will travel too far back and push the rod in too far on the deactivator switch. Its a one way ratcheting rod so once it is in too far you either have to get a new one or bend the metal tab on the pedal a little more to compensate.

Easy test for deactivator switch adjustment is while driving to use your toe under the brake pedal and pull up on the back side of the brake pedal (like your trying to release the brakes) while turning on the cruise. If it activates every time, switch adjustment is off.

I put the deactivator switch back in the pedal assembly after it is all back in the car and connected. It just goes in the pedal bracket and twists into place while holding the brakes on with my head or arm. The rod only has to move a slight amount to open the switch contacts and cause no cruise.

I tried pulling up on the pedal with my foot too, along with twitching the steering wheel. Still nothing. Cruise worked fine again this am. It's got to be a faulty servo.

Twitching the steering will not fix a bad clock spring. Lol

[Zack]

How bout verifying the servo is getting power when it's supposed to before throwing parts at it?

Not fix, but test. Everything on mine worked just laying my finger on it either direction. Dead straight and only half my controls worked.

I'm fairly certain a *results may vary* should be attached to that

Because the last one exhibited the same symptoms and a new/used one fixed it for about a year. The servo I "threw" at my Town Car fixed that one too. I suppose I should not have even posed the question.......

Very true. After all, it's just a ribbon.

No need for hostility, just makes no sense to guess when you could have tested.

No hostility intended. But I don't "throw" parts at problems. Based on my observations and past experiences, it seems like the best solution. Besides, it is very difficult to dissect electrical issues even if you are trained in the art. And I am not.

If I was closer Id let you borrow one. I know I have a spare somewhere.

[tbone]

Thanks for that.

If the problem isn't the servo, I will have an extra for a rainy day or a low mileage example to sell to someone in need.

I'm planning on starting to hoard parts when and where I can anyway.

[tbone]

Installed the new servo today. Thankfully the problem is fixed.
