just successfully diagnosed first problem with new van using the info found on this site. thank you > and will be replacing a bad Temperature Sending Unit. the dash temp gauge works it's just the Unit is bad.
i noticed while i was checking the gauge by grounding the connecting wire: the Unit below the Temp Sending Unit was unplugged? i re-connected it. even though i bought the official Repair Manual for my 1989 Van i couldn't figure out what that unit was and what purpose it serves?
here's a photo - anybody know what this is:
