Ok, the cruise control accelerates when I push forward on the lever, but it won't stay engaged, any ideas?

Cruise control systems on these cars are notoriously evil. Could be darned near anything from a faulty computer (they tend to fail), bad servo (the part under the hood with the cable to your throttle linkage), or a signal coming from the brake or clutch switch "fooling" the computer into thinking that you either have the brake on or the clutch in (either of which will disengage it). Oh, it could be the steering column switch mechanism too.

Check out pelican parts or clarks garage, they have some write-ups on diagnosing these systems but mostly you just have to replace stuff until it starts working again. . .

Thanks, pelican parts and calrks garage, are those websites?

Yea, you can google for them or they're:

Thanks again!

mine would do that, then it gave up completely. I took out the circuit board (left wall under the dash) and reworked all the solder joints, works beautifully now. Didnt cost a thing but time.

Yea, I've heard that too (I believe the write-ups get into this also). I pulled mine & looked at it; all of the solder connections looked okay, but I've since learned that they can LOOK fine and still not conduct well. I guess I'll know for sure in a week or so - I was recently able to score two new (well, used) computers for $25 and I'll see if it works when I swap out or not. I might just try brushing up on my soldering too if I get ambitious enough. . .

Best of luck with it in any event!

Send a message to JoeJackson, he'll resolder it, and fix it, for around $25

I encountered the same problem ... bought a used cruise control brain ... switched it out and it has worked fine ever since ....

Thank you all, much appreciated! I'll more questions later, as I'm trying to work out all the bugs on this baby. She sure is purty.

solder, solder, solder!!!
fixes most of the time, especially the symptom you described!
good luck

do I just resolder every terminal on the circuit board, and am I supposed to add more or just heat up and melt the solder that's already there, cause I looked at the board and it "appeared" to be okay.

inactiveuser92616

I just went around and reheated each point until the solder fully re-liquified, then moved on. Make sure when all is said and done, that you have not allowed any short circuits to form with the flowing solder. (Test with multimeter any suspicious spots.)

A few joints I had to add more solder, but not many.

every circuit - every solder joint. Not all cold solders are visually apparent.
