Good news today. I changed out the wiper motor and it works perfect. changed the vent motor and it works perfect. Had a problem with the third brake light with one bulb not wanting to work. Fiddle with the socket with my multimeter and blew the fuse. Changed the fuse, came back it was working as it should. So now I have just the mirrors to worry about until something else happens. When I tested the mirror on the driver side, i had power to the mirror (signals still worked) and power at the switch. I bought a new switch and will change that out in a few days to see if that fixes it. It may be the mirror motors are just done. They are originals and I do have 245,000 miles on it. I find it odd that all these motors would go bad at the same time though.

My mirrors are in the same boat, only partially working. Fortunately, Expeditons/F150s/Navigators re pretty common in junkyards here

Thanks Travis. Do you happen to have a picture of what I would be looking at? It is hard for me to get down on the ground and only want to do it as little as possible. My back doesn't allow me to do all the things I want. I would love to have a lift..in a garage...with a bunch of cool tools....lol. Thanks for the advice. If I can get to it, I will take pics and show what I have. Maybe I can go from there. I may have to take it somewhere to actually change them.

The fuse was fine for the wiper, but not for the third brake light. I blew that myself. I haven't tested the rear wiper today, but I am sure I will later. Electrical issue are the worst issues. I much prefer nuts and bolts....

Searching is a good skill. But due to misinformation, I'll paraphrase it:
Help, my battery keeps dying
Do a parasitic draw test, note the reading. Repeat with the rear wiper fuse pulled. Did it change?
If it did change, your rear wiper isn't parking. Limit Switch inside motor is suspect.

...or the wiper arm isn't installed in the correct position. You fix this by removing the arm, run the wiper, then turn it off and let it park, then install the arm. If the arm is installed too far to the right it will land on the stopper even though the shaft hasn't turned far enough to reach the parked position, thus keeping the circuit energized.

OK...Got to work on the truck today. No more testing. Everything is working as it should at the moment. My brother unexpectedly sent me new power mirrors. I put them on today and they work perfect. Could the old mirrors just have died? Anyway, thanks to all that provided input and help along the way. Took me a few hours but it was worth it. Now what to do with the old mirrors? I can't just throw them away. The glass was new old stock. Guess they will sit in the garage with a bunch of other crap I can't seem to throw away either.
