You have a short to ground in the park light have a mechanic look at it because its possible the trailer wiring was faulty and shorted out the Smart Junction Box (SJB)...the park lamp relay is controlled by it and the relay is built into the SJB

Trying to find the problem to why my park light fuse keeps blowing?

You are replacing parts but you should be focusing on wiring. you will need to physically check all the wiring for the rear tail lights and the front park lights for shorts to ground. you can also unplug all of the bulb sockets, replace the fuse, and see if it blows. if it does than it is in the wiring. If it does not than plug the sockets back in one at a time until the fuse blows, then inspect or replace that socket.

Why does my tail light fuse keep blowing on 1981 f150.

You either have a dead short in the system, or now need a higher amperage fuse to account for the draw of the trailer lights. If it occurs even with trailer not connected it's a dead short. Check system for any spots where bare wiring comes in contact with metal.

1998 Chevy Silverado 1500 Brake light fuse blew, replaced, fuse blew again, replaced relay and fuses. both under hood and in side fuse panel. Fuses keep blowing on turn signal and brake lights. Checked...

you obviously have a short to ground on one of the wires to the back (if it was the front the brake shouldn't blow the fuse). the most common problem is usually in a trailer light harness. if you look under the drivers side rear of the truck, down under the tail light there will be a plugin junction. pull this plug-in apart and see if the fuse still blows. if it does then the problem is forward of that connector, if it doesn't then the problem is behind that plugin. be sure to check for "green death" (electrical corrosion) at all joints especially any trailer hook ups.

Tail light/dash light fuse keeps blowing

The dash lights and parking lights should be on two different fuses.
You may have a problem with the headlight switch, or something in the harness.

maybe one of the light connections is grounding out? check the light holders to make sure there is nothing pinched or worn through on the back of the lights.

2001 mustang v6 automatic convertible keeps blowing fuse #10 (park, tail lamps)

The fuse doesn't blow till you turn on the light switch? If it blows before turning on light switch, look for a short to ground between fuse box and light switch.
If it blows after turning on light switch, I believe they make a short finder tool.

Parking and tail lights out after plugging in trailer with bad lights. uhaul said all fuses were fine and sent me on my way saying it was a common toyota problem and basically blew me off.

I"ll say, and what a **** for causing the problem, and then not fixing it. I would complain fiercely to U-haul. If the lights were fine before hooking up to trailer, and then went out, they obviously caused it. And it's not a "common toyota problem"...they're just trying to get out of it. Possibly they shorted out your headlight switch.

Blows fuses when parking lights are turned on. Headlights work fine even running lights.

If it only happens when you turn the switchto the parking lights then it is most likely the swich that is the problem. Light swich failure appears to be a common fault with fords

No brake lights, fuses keep blowing and wont shift out of park

I would look for a wiring short in the trunk at the taillamp area, or, inspect the sockets for the taillamp bulbs for corrosion. In any case, you have a short circuit in the trunk area, also check the wire that comes from the body & goes up the trunk hinge on the driver side; that wire may be chafed, and it may be shorting out. Hope this helps; please get back to me if you need any further assistance.
