Last week I had the balance shaft seal replaced on my 90 Honda Accord
4 cyl. 2 days later the electrical system went nuts. Oil light, wipers,
parking lights and some buzzers go on and off at random. The rear
window defroster sometimes doesnt work.

Shop that replaced the oil seal says this has nothing to do with what
they did and is probably a wiring problem under the dash. They do not
work on wiring and recommended I take it to the dealer.

Help
