Cruise Control not working - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

I drove the Grand Marquis the other day (I like driving my '94 Buick Roadmaster better!), and noticed that the cruise control quit working. The wife was perplexed, as she told me she just used it the day before. So, when I went home, took off the fuse box cover, and checked the two fuses (numbers 1, and 6 I believe) that had speed control in the description, and they were both good. Any thoughts? I didn't read anything else in the owners manual about speed control, with any of the 'big' fuses, or relay's under the hood.

Thanks,
John

Found this info that might be of help.

check the servo deactivation switch. Located on the brake pedal arm under he dash. This will require you to remove the black plastic duct fot shield to expose the under dash area. It only has 4 plastic speed grommets. You will see to switches on this brake arm. The lower one activates the brake lights. The upper one deactivates the cruise control and is a common failure in 1998-2002 Ford mercury Crown Vics and Marquis. Remove the connector(also known as connector c223), and check the continuity of the switch opened or closed. It should change from infinite to a short using a standard voltage meter set to ohms or continuity and pushing the brake pedal.

Thanks, I'll check that out! If it's bad, then I'm assuming that it's a 'dealer only' item? If so, then would you happen to know the part number, so I can order it?

Thanks,
John

You should be able to get it at your local parts store.

Here's a weird one! When the wife drove it to work today, she said the cruise now works! And, I didn't do anything, except take out those two fuses, and put them right back in! So, either I 'fixed' it by doing that, or there's a loose connection somewhere.

Possible corrosion build up in the fuse carriage?

The cruise on my 2000 GM LS is weird too. If I have the cruise on and have to hit the brakes for whatever reason, it goes off like it should, but then it doesn't want to come back on. I have to press the off button and then turn it back on a couple times before it will resume. The resume button only works when it wants to. I've learned to live with it, plus I don't do a lot of highway driving so I don't use it that often anyway. Perhaps some day I'll get around to fixing it. Did you get yours figured out?
