Removed the cluster to replace a damaged CEL light.I replaced the bulb, reinstalled all the screws back into the circuit board and cluster, making sure all screws were put back correctly, some were longer than others. I reinstalled the cluster and the temp gauge pegs to hot? Removed cluster again, reinspected the screws and circuit board. reinstalled cluster, now fuel gauge pegs to full, temp gauge stays cold? tested all fuses under dash with a test light, all appear good. What did I do?? what do I check?? thanks in advance.
