a wet 98 E300
he left the sunroof open and it rained ... got soaked
> both seats wet, little water on drivers side floor board, mat & carpet soaked in right front, the console got really wet undoubtedly ... and about 2 inches of water standing in the battery compartment.
> Several things started to happen, alarm system horn wet off while driving it home, no pwr windows, no pwr mirrors, no overhead courtesy light in front, the one in the rear come on and stayed on, parking lights & tail lights flicked on & off, now both sides on all the time ... radio, heat & a/c worked fine.
> Dryed it out ... everything so far has returned to normal, except the parking lights, tail lights and overhead courtesy lights.
> Assume there are relays that went bad? Assume that cause when the fuses were pulled for the parking & tail lights, the right side lights, stayed with no fuse!
Can someone point to a manual or papers for the relays and any hints for replacing them ... how do you tell one from the other ... should i replace all of them to be sure?
Thanks,

Test the fuses as there are no relays for the tails and park.
best to disconnect the battery and not be testing anything more until it is fully dry.You don't want to fry your shift module
here's an inventory of what's wrong ... maybe this might suggest something ..
1) no auto locking, when driving or with the key fob, locking doesn't work even from the dash button.
2) have no alarm, if i lock the car w/window down, pull the plunger up and open the door, no alarm, goes for the hoof and the trunk
3) no automatic courtsey lights when the door is opened, fooled around with the setting to make sure it was set to auto. can turn them on manually, tho
4) trunk will not open by pushing in cylinder, have take the key, turn it & push in
5) when car is initially started, get a defective lamp on the dash, assume that is related to the parking and tail being on constantly
6) when running, if flip the brights on and the off, get a defective lamp on the dash
all other lights work as normal, head, brights, license, back up, brake ... etc
Also, recommend strong negative feedback for the culprit (curfews, TV ban, allowance cuts, etc.)

all the connections are rusty ... and when I took it apart the contact board was a mess with rust ... both the bottom & the top ...
I am checking to see replacement cost, personally believe it is too far gone ... to clean up ...
6) when running, if flip the brights on and the off, get a defective lamp on the dash

For #6: Are you running your fog lights in addition to your regular lights while doing this procedure? If so, when you have a fog light out, it will trigger an error message when switching from normal to brights.
