    Dash Temp Gauge not working

    Hey everyone. I searched for a while but couldn't find what I'm looking for. I recently bought an 86 LE 2wd. Had a code 4 so I replaced the water temp sensor while doing a basic tune-up. Van runs great but now the temp gauge on the dash isn't working. Checked for loose connections that I might have bumped as well as all of the fuses. Everything looks okay. No codes either. Is there another water temp sensor I'm missing?

    Re: Dash Temp Gauge not working - Resolved!

    Okay, resolved this issue. I took the passenger access panel back off and inspected very closely. The temp sensor in the block (1 wire) and it's connector looked good. I cut away some of the heat shrink and found part of the wire exposed from a crack in the insulation. Clipped the wire back, installed be end, re-connected the wire and we're in business.

    Guess the years under the hood can cause all kinds of electrical gremlins. Just glad this one was simple.
