Cruise control on 99 taurus

While you\'re still blindly changing parts, just go to pull a part and pull a body control module, a cruise control module, and an engine computer. Send me all the stuff you change out that doesn\'t fix anything, I can test them and sell them.By then, you should have enough money for a mechanic in used part sales.

This is just a guess and they can keep my point if I'm wrong :) but I would start looking around the cruise unit itself under the hood for loose plugs or, in some cases loose vacuum hoses. Some cruise units use engine vacuum for unit actuation, some use it as an indicator of engine speed though now it's mostly sensors and servo actuators operated by computer. I can't speak directly about your unit but sometimes, in all brands of vehicles, when you change something that is computer controlled, you have to reprogram the computer so it can accurately sense and operate the part or machine. Good luck. Jeff M.

cruise control starts working above 50kmh, so if your under that it wont work. the cruise servo may be at fault, or I have seen battery acid leak down on the vacuum lines causing cruise not to work correctly. cruise control works off of a vacuum so without it, it wont work. if the cruise light doesn't turn on when pressing the set/cruise button intermitantly it may be the switch itself that is starting to fail

might have to replace the whole steering colum

The cruise servo went bad. Replace. Under the hood.

open the hood and check to see that the throttle cables are not out of place, if everything looks ok then unhook the cruise control cable from the throttle body (black plastic end) by pulling up on the cable end. this will disable your cruise control from making your car accelerate at unwanted times. sounds like there may be a problem with the cruise control servo.

1. Have you looked at your owners manual for location of the cruise control fuses? 2. Same for the tachometer? 3. Do you live in a wet area with alot of rain? Next chance you have, get some electric cleanout spray from NAPA spray into all cruise control connections and tach connections. 4. Check the recalls from Ford there have been issues with 99 cruise econtrol systems.

Could be a vacuum leak. Check hoses at vacuum reservior and cruise control motor.

Nope, I didn't get a solution so the car headed to the shop today to be fixed by someone else. I try to do my own maintenance but this one had me baffled. Thanks.

make sure your brake light are working propelly because the cruise circuit is atached to the brake lights and if they don't work then the cruise wpn't either
