Thanks M.A.C ! Replaced the idle speed control motor and idles perfect now , I don't know what a Panel Dimming Switch Pot Circuit is , or where it is located , any help would be great as it is pretty anoying driving at night with the dash lights flickering like a strobe light , THANKS :wink:

The dash lite dimming circuit in the headlite switch or panel switch is bad.

Thanks max , I will check the switches .
