No dash lights parking lights or taillights on 06 ranger

[Hdrger]

Lost my parking lights dash lights and taillights and fog lights. I've replaced headlight switch dimmer switch taillight sockets and bulbs put it new fuses and switched relays around, now sometimes they work and sometimes they don't. I even pulled the harness off the fuse block inside on the right side kick panel and found corrosion, sprayed and cleaned it up put back together and nothing. Went out the next morning and lights worked for the next 4 nights, next morning nothing and that was 3 days ago.

Sounds like it's definitely something in the park lamp circuit.

You need a schematic and a voltmeter... being intermittent...I would be leaning toward a poor connection in that circuit.
