I have a problem with the cruise control.
When the cruise control is selected , and I want to kick it out by steering
on the brake , it does not release. From time to time it does. I have a
feeling it is a loos micro switch somewhere that is loos or worn out.
If I deselect it on the selector at the steering wheel , it deselect
So the question is , where is the deselect switch situated that deselect the
cruise controller when you step on the brake? And is it difficult to
Thank you .
Even before taking anything apart, I'd have someone check the brake
lights while you step on the pedal. As was pointed out, the same
switch works both, so it's possible your brake lights aren't working
either, which is dangerous.
I took the switch out , and tested it , and it works fine . Not

sounds like the module is kaput. You can get remanufactured ones for

having your wife tell you if the brake lights are on is not valid. I had a
similar issue to yours and it turned out that the brake lights failed to
come on about one out of 10 times, and even then it was not consistent.
I took the switch out , and used a Multi meter and cycled it several times.
To get to it , I had to take out the cruise control amplifier , and that
meant taking out the plug for both things .
This has probably solve a bad connection, by re-plugging it.
