Hi. I have a problem with my car's temperature and fuel gauges. My car is 95 Civic DX with D16Y8 engine. What happened was, I pulled out the gauge cluster to fix the erratic speedometer gauge. When I put the cluster back in, and turn the car on without starting engine, my temperature and fuel gauges started going up all the way to max. I tried to tighten and loosen the sensor screws in the back and still didn't change anything. When I take out the sensor screws gauges stopped working. I'm assuming, sensors are working fine but something happened to gauges. Anyone familier with this kind of problem? Please help.

P.S. My speedometer is fine now. The sensor screw on the back was loose.
