Cruise Control Help

[White Stripe]

a lot of times the plastic casing cracks and water gets in there causing it to go bad

Ok. I will get under mine and check it out. Looking into getting a used sensor.

When I bought my rig the cruise control did not work either. It actually turned out to be related to my trailer light hopper (small black box behind rear panel). When I replaced that, all was well. May not be related at all to the your problem, but it was with mine.

the cruise control on a 92 is pretty complicated it does actually tie into your tail light per the FSM it took awhile for me to troubleshoot and test out one thing at a time it was a pain in the acid but I finally got it

Easy peasy OBD test will confirm whether or not it's the speed sensor. (It likely is on a 91-92.)

Why do you keep saying that?

The on-board diagnostics exactly pinpoint the problem circuit.

it's not the diagnosing part that is complicated what I meant is the entire system is complicated there's a neutral safety switch involved it ties into the tail lights speed sensors and some other components what I found is the onboard diagnostic for the cruise control doesn't always pinpoint at 100% you physically have to get in there and check each component with a meter besides maybe white stripe doesn't have the FSM to help him through the diagnostic procedure
