1993 ranger 2WD 5 speed. I'm still new to this truck so I'm trying to work through the issues. I don't know much about cruise control systems. I was wondering where I should start. Pressing ON on the steering wheel and SET/ACCEL doesn't set my speed. I would like to get this fixed if at all possible. I looked at the unit under the hood and it looks like it has a vacuum line and some linkages. I also read about some self test procedure but i didn't see a year listed. Is this OBD2 or does it also work on the older rangers like i have? see link here ------> https://www.ranger-forums.com/genera...l-fuse-128938/

I also read about a brake switch of sorts, what test would this require and how hard is it to reach?

Thanks all.
