having wiper and door lock problems

I own a 93' sho. My wipers wont go all the way down and the delay is not working. I was told by the previous owner that it is probably the relay because the auto down on the windows is also not working and they share a relay. I bought one but can't seem to locate the relay in the car.

I am also having a problem with my power door locks. If I use the switch on either door, the locks start going crazy and wont stop until I turn the key to on.

If anyone can help it would be greatly appreciated.

P.S. I know this question has been asked before, but by no one with a 93'. I have tried the suggestions given to other members for 92's and 94's but Iam begining to think they don't pertain to me.

It sounds like you might have a bad ground somewhere, you can try looking around for wires that are connected to the body of the car. Check to see if there coroded or broken loose. Wish i could be more help but I have no experience with the SHO's. If you figure it out please post your fix, we would love to hear what turned out to be the problem.
goodluck
