1997 passat sedan tdi electrical

soo, back again with another problem. im driving on sunday and its pissing rain. i go to switch my whipers to a different setting and i notice there is no change. i go to turn them off and there is no change. they stayed to the adjustable intermitten whiping setting i had set. i shut the car off in a parking lot, then turn it back on hoping it was something random. sure enough it persists and they do not shut off when i turn the back on. i shut the car off a second time and spray the windshield to clean it to see if they would automatically shut off, as they are supposed to after 3 or 4 whiping motions, they didnt shut off again. the next day the problem seemed to go away. they turned on and off fine. and today it happened again. ALSO this time i turn the car on and there were no automatic headlights, and no interior lights. i started pulling fuses and checking them. i ended up not finding any of them blown but since i didnt know the last time any of them were replaced. i replaced them all and started fresh. that same day the 6 speakers did not have any sound what so ever, and the only thing playing was my set of subs in the trunk. i know the subs have an RC cable which rund from the radio so i do not think its the radio, or else i believe the subs would be doing nothing as well. do you think i should check relays? i know some vdubs have been known to ahve wiring problems that could make you go blue in the face. would the wiring harness be burnt out or something? i am truely at a loss for what to do next. any suggestions are greatly appreciated. please post a reply if you know anything what so ever.
