Hi Scotty, the instrument cluster of my 2007 Camry has been misbehaving for a while now. While driving, the ABS and brake lights come on and the speedometer goes to zero while the tachometer needle flickers. Also, the temperature gauge goes to C and back and the the air-conditioner stops cooling.

This all happens on and off as I drive but the car drives normally. What could be the problem?

start by having the battery and alternator load tested, auto zones do that free. if not that, remove the dash and check for loose wiring connectors

Thanks a lot.
