I just bought a 95 probe gt 2.5 v6 and I never know what the temp is, it is stuck in the middle, the trip odometer don't move stuck at 75,xxx it says the speed just not how many miles,my oil pressure is 1/4 the way up from L when driving.

Just give it a whack! If that dont work you can try to find a used gauge cluster

I'd just go straight to a junkyard and start searching. The one I am working on currently also happens to not work *sniff*
