The temperature gauge on my 95 Excel (125000km) shows that the vehicle is overheating however this is not the case. When I activiate the left turn indicator the temperature guage moves straight to hot then moves in time with indicator. When the indicator is off the gauge returns to approx 3/4.
Do you have any thoughts on what might be causing the problem?

Wires are bundled under the dash. Somehow two of the wires are touching, whether it is a faulty shielding or something has gotten one of the wires hot to melt. This is just a possibility or another is to look at the instrument cluster itself and see if you can see any obvious problems.

Suggested Repair

Inspect the bundled wiring under the dash for wires touching due to damaged insulation or heat damage, and check the instrument cluster for any obvious faults.

Conversation Summary

The owner of a 1995 Hyundai Excel reports that the temperature gauge falsely indicates overheating and jumps to hot in time with the left turn signal, then returns to about three-quarters when the signal is off. The expert suggests two wires under the dash may be touching from faulty shielding or melted insulation, and also recommends inspecting the instrument cluster for obvious problems.
