electrical problems-- has anybody ran into this??

[Hoosierdaddy]

I have a 71 I'm trying to get rolling. I finally got the big block purring smooooooth. Now I'm working on other little details like tail lights and replacing steering wheel and fixing things like sticky windows. Problem one: I was working on sticky windows and sprayed some Tri-flow on rails and pivit points. Now the window drops about 2 inches as soon as you close the door. problem 2: trying to fix tail lights... I checked for power at fuse box good on both sides of the fuse.. checked half way back under truck, power there too... got back to the plug and no power. went back to half way and nothing. checked wires as the come through dash, nothing.. went to switch and had power in but nothing else. turned lights on and off then I had power again. but tail lights still don't work. I replaced the switch with a new one... Now the dome light wont shut off, and the head lights appear to be on low beam but the light on the dash in indicating high beams. I got a couple burned out bulbs in the dash to replace, but that surely could'nt be the problem. Has anyone every ran into these problems? Also the left blinker flashes fast while the right flashes slower....



Thanks
