Default 2002 tahoe electrical problems Computer??

ok so here is the problem the other night i was driving and came to a stop and the truck died on me and would not restart but all the electrical was going crazy i.e. rear wiper was on but the switch was not on all the lights on the dash was on the flashers would not work when i pushed the brakes all the light would come on. so i was two houses away form my buddys house so we pulled it there and i disconnected the battery( hoping to clear the computer). the next day i went and tried to start it and it did but not very willingly. once it started i had to keep feathering the gas to keep it cranked but eventually it cleared up and ran on its own but the rear wiper was still doing its own thing and the dash light were still on but i decided to drive it home(10min). by the time i got home the rear wiper had stopped and the dash lights were off except the one that said "service 4x4". i then turned it off and restarted it and everything was back to normal. after talking to my dad whom is a mechanic but for nissan for the passed 20 something years i decided to go get the battery and alt. check and the battery failed so i but a new in and i drove it for a day and a half no problems until today when the rear wiper and the dash lights came on again and i noticed that when i bush the brake the rear wiper will jump.
if anyone has any suggestions please let me know.
thanks
jason

Welcome to the forum.

Can you say "exorcism"? Seriously tho, I would get it scanned for codes. Has any work been done on it recently?

On another note, shift key, punctuation, and paragraphs aids in reading text.

x2 test the alternator. if that is not it make sure your pcm is connected good, that can have some of the problems you are having.

check the ground cable from the battery to the block, it may look fine from the outside but can be corroded, high resistance or loose and will cause all kinds of strange things to happen. It should read 4 ohms or less, it needs to be as close to a dead short as possible.
