I have a Sienna 2000 model, when I put on the head lamps within 10 minutes the Odometer display goes blank and the reving dial will not rise on motion, then the automatic gear selection begins to jack. After switching off the head lamp while still on motion, everything normalizes.

The same scenario happens when the weather is very hot without putting ON the head lamps. On motions it will normalizes sometimes and after sometimes it goes blank.

I have checked the alternator charging, it is okay.


Kindly help with solution if you have encountered such problem or you have the idea what the problem could be

Thanks

Check ur wiring, maybe rats have visited your car.
