86 TBIRD ELECTRICAL PROBLEM SOME THINGS WORK SOME DON'T (CAN ONLY DRIVE DURING THE DAY)

1986 Ford Thunderbird • 150,000 miles

Fired up the 1986 Thunderbird after sitting for a few months, but started every two weeks. Some things work some don't. Re-seated all the fuses in the fuse block which made it possible to start with the key, Re-seated the headlight switch with no change. Still have some "minor" glitches. Hoping it's a loose connection somewhere
Question is where to start, heading under the car to clean starter and ground.

DOES WORK.

Directionals front and back
Brake lights with cyclops
Wipers
hazard lights
power windows

DOESNT WORK

Clock
power door locks
Power mirrors
power seats
odometer does not show numbers (digital) but does light up
Headlights high or low beam
dome lights ( center and spots)
driving lights

Did you test the fuses? Reseating them is not going to work if any is bad. With so many components not working, I believe it most likely is due to a bad fuse unless you have rodent damages to the wires.
