I seem to have an odd electrical problem with my car. The first one is the driver side door. Usually if you insert the key in the door and turn to lock/unlock, it should unlock all doors. Instead, you have to hold it for a couple seconds until it responds. (The passenger door behaves correctly and immediately locks/unlocks all doors).

<FONT COLOR="red">Supposed to be that way. When unlocking drivers side door, you may not want all the doors unlocked so you have to hold it. Passenger side, they assume you are letting people in or whatever and all doors unlock. It's a nifty feature.</FONT>

Another problem that seems to be the same problem is my winshield wipers. If I turn it on int/low/high, it won't work for about 10-15 seconds...even at the fastest setting. But after waiting a while, it kicks in and after that point, it will work fine. But if I turn it off and then try to turn them back on again, it will stop for about 10-15 seconds until it kicks back in.
<FONT COLOR="red"> The wind shield wipers tuck themselves out of the air stream when turned off....better gas milage. Once turned on they must untuck then start wiping.</FONT>

Would corroded wires cause something like this? Any ideas? Do you think the door and winshield wiper are the same issue?
