When I drive the cluster freaks out, the battery warning light comes on and the gauge will go to high. Then after it freaks out for a couple seconds it turns off and goes back to normal. Also the radio and climate control will turn off.
I have checked all the fuses and the acc relay and all is fine.

Good morning,

What is the charging voltage at the battery while it is running?

Have you cleaned the battery cables?

This sounds like a voltage issue whether high or low.
