No trunk light,do all switches light up when head lights are on,windows,top,map light switches,side interior light switches,speed control,flasher and defrost switches? dash lights very weak dimmer switch turned to high, bulb indicator light on.
Thank you.

 

As regards the dimmer switch these do fail over time and the usual trick is to remove the switch and bypass it by joining the wires together; this should show an improvement.
If not the only option is to remove the consol and clean all the contacts and replace all the bulbs; LED bulbs seem to be a popular fix which i will do when sorting mine out (I have no illumination at all!)
