My 95SW headlight relay beneath the fuse panel is getting really hot when the truck is running but, doesn't matter if the headlights are turned off or on. It's probably been that way for ages but, I just noticed it while I was changing a fuse. The hot relay clicks when you take it out and put it back in with the headlights off or on. Headlight high and low beams are working fine.

Solved brake light issue. Contacts inside the bulb fixture were bent and not making good contact with the bulb. Problem was...Passenger side brake/tail light going out when brake pedal pressed with headlights on. Dim passenger side brake light with headlights off.

Is the headlight issue the classic switch problem? If so why is it getting hot with the headlights are turned off?

This to wild. I had basically the same thing happen last night in my P38.
Only my radio also went out and I couldn't shift out of park.
Said I blew a bunch of fuses all at the same time. I'm wondering if I have a bad fuse box or wore harness.

the p38 has always had issues with the fuse box located in engine compartment, check all your connections for corrosion and or water damage..

With headlight switch and high/low beam stalk disconnected, relay still gets hot.

If I pull the hot relay the headlight switch does not work, lights go out. The high beams will still come on without the relay if you pull back on the blinker stalk.
