I just bought this 92 Deville and as soon as I took it out of the used car dealer, the dashboard display started flickering. It appears to be more noticeable at night but still happens during the day even with the Twilight Sentinal switch off. Any help from the experts will be helpful!:cookoo:

Check all your power connections and grounds. You'll also want to get under and check the connections at the starter solenoid. BTDT.

I checked battery cables, ground connection going to the solenoid and everything looks tightened. I also cleaned the fuses cuz they seemed dirty. The problem still occurs. You can hear the clicking of one module underneath the glove compartment. I think is some sort of controller. Could this controller be going bad? Any ideas?
