This is my first time posting a thread so if i am doing it wrong tell me. But any ways, I have a 95 mustang gt with the 302 in it. I am having a problem with my water temp gauge and my oil pressure gauge. They apear to be reading very high and seem to be following each other somtimes. But the car doesn't seem to be over heating like the temp gauge says. I have put in a new thermostat, a new water pump, new radiator cap, and new temp sender. But still the same. The gauges also go up when i turn my lights on or close my window. It's driving my nuts! Please help! Thanks

 

Check your grounds.

 

I have check all the grounds under the hood already. Is there any grounds behind the gauges cluster?

 

No there is no ground behind the gauge cluster. Does your gauges go up when you run the window up with the motor off?

 

No with the car not running the gauge doesn't move when you turn the lights on or roll up the window.
