Cruise Control Gremlins Have Surrendered

[goody90q45]

I've owned my 90Q for about 4 years (bought, sold, bought back) and the cruise control (CC) has never worked. In the past couple of years I've swapped in all the individual CC components- controller, ON/OFF switch on dash, set switch on steering wheel, relay, and the diaphragm and actuator under the hood, all with no luck. I still checked it while driving every couple of months and the green CC light would never come on in the instrument cluster.

Yesterday I did the check and I'll be darned but the CC was working. About the only thing I've done since the last check is to pull all the under dash fuses to check them with a voltmeter while chasing a defroster problem. None were bad. While checking fuses I also played with an interrupt button that's wired in that I assumed was for the telephone. I've pressed this switch many times before but think I may have pressed it this time with the engine running.

In the last week the seat and steering column have also started moving when turning off the engine but it's been intermittent for a long time so I'm not sure it's related. Regardless, I use CC a lot in my other cars and I'm pleased to have it working again in the Q. We'll see how long it lasts.

Very interesting.. I would say in my experience the most common problem with the CC is one of the brake switches going bad or a bad connection there.. only having one will still operate the brake lights, but you need both for the CC to work.

I wonder what that "interrupt button" is for? Can't say I recall seeing one of those..

I would die if i didnt have cruise control.. My commute is about an hour mostly highway driving, and it would really suck not having that!

In the 250,000 miles I have driven in my Q, I bet I have used the cruise control less than 50 total miles- for some reason, I would rather have my foot on the pedal! same with the previous 3 other cars I had before the Q that all had cruise control!!!

I'm with Wes, cruise control RULES!

Same, I hate the feeling of the car "being driven" without my input. I get paranoid and always turn it off within 10 seconds. 12 years I've been trying to sell myself on cruise control to no avail.

I have been riding around without a (Side) mirror switch, Cruise Control (ASCD) Master switch and Microphone (Not needed) for longer than I can remember. My guess is close to a year.

My guess is that you may have a wiring problem Goody.

I forgot to wish you all a Happy New Year, so Happy New Year all!!!
