I'm not familiar with the 4 cyl but it sure looks like the connector has
a broken off tab stuck in it. Go looking for a sensor with a broken off
tab or connector on the top.

Nope, no AC.

Jeff's idea about the temp sender may have some merit, though, since the
dash temp gauge has been extremely erratic when it works, which isn't
often. I'll poke around some more today if this rain lightens up.

Thanks again!

I didn't know there were two different senders for temp... That *would*
explain the dash gauge's reluctance to work properly. :)

Thanks!

Sorry, but.... If that is a temperature wire, the gauge would 'not' be
working.

Did you stick the spade connector into that plug or does it have a
broken wire inside of it? If that spade was there, then the rest of the
plug is around, likely just as a broken off wire remnant. I would be
looking under the vehicle for the wire dragging along.

If it was for the AC, you wouldn't have a spade in it, it would be
empty.
