Hi Bob,
Check your earths to start with - power supply to the dash is the orange lead if Scorps are the same as Montes. Have you tried moving the dimmer? That could help. It's not a difficult job to take off the dashpod and clean all of the terminals and contacts. You can also replace the old bulbs with LEDs so you can actually see the dials in the dark!
On the hazard lights, dismantle the switch and make sure that the terminals in the switch are clean. Also check each wire for continuity. Are your indicators working?
Hope this helps.
Cheers
Darren
