Interior lights and power locks not working

[GNRick]

Pull the wire off the cig. lighter as that is probably shorted. Then put in a new fuse. If all is good then replace the lighter.

That totally worked!! Thing is it is a new cig lighter. Should there be a rubber washer or gasket between the lighter and the hole in the dash? Not sure why it's shorting out. But now the security light blinks constantly??

when you tighten down the stud on the lighter the hot clip can rotate to touch the ground casing. Make sure it's centered. A voltmeter set on diode test will stop beeping when you get it right.

Just bought a t type regal 84. I’m having the same issue interior door locks digital cluster– power seats, AC courtesy lights glove block lights trunk lights are not working the fuse is not blown. Could it be the radio capacitor? I do have a wrong size battery in the car could that be it.
