Hi,
I had to Jump Start my car and since then my car Guages will not operatre. ( Engine coolant temp. Gauge, Tachometer, Speedometer, Fuel Gauge and the Multi Information Display.)

I tested all Fuses in the car and in the Relay & Fuse box near the Engaine. All the Fuses are good. (I don't know how to check the Relays.)

Please help me,

Ron

Hello,

There is a IG2 relay that needs to be checked here is the cluster wiring diagrams so you can see how the system works and a guide to test the relay with the relay location as well below.

Check out the diagrams (Below). Please let us know what happens.

Hi,

I had to Jump Start my car and since then my car gauges will not operate. ( Engine coolant temp. Gauge, Tachometer, Speedometer, Fuel Gauge and the Motor oil pressure.)

Could you help me out with these problems?

I wait for your answer.
