Just as the title says, I swapped the instrument cluster from a 99 auto to my 99 man. Watch the video below. Could this be a difference in the pin-outs of the plugs? This happens roughly 30 seconds after the ignition is turned on.

This is booooring... Anyone take a stab?

 

Hey buddy
Its not a difference in plugs or whatever, its the temp gauge itself thats messed up. If you take your cluster apart and look behind the temp gauge, there are tinnnnnyy little hairlike cables that make the guage move up and down. These little hairlike cables have current and if just 1 of them breaks, then thats what happens to your gauge. Get yourself a magnaphine (sp?) glass and look very carefully at the little cables. There should be about 4 little terminals in the corners, this is where most of them spap off. If you get lucky and find the problem, then you have to weld the 2 cables back together.
I have this ongoing problem with my eg cluster. Swap temp/fuel gauges from another cluster or whatever is your best bet.
Goodluck buddy and LMK.
