w 140 Door lock computer w/ shorted board

My first post and I am sure this subject has been addressed before. Just bought my first MB it is a 1999 S500. I love the car except the door locks don't work. I have traced the problem to the controller under the rear seat. It appears to have gotten wet, probably by a spilled drink. The pump works fine but the control board is toast. Can a control board be bought?
If I replace any parts, do I have to reprogram anything? Any help would be appreciated.

i have several core pumps that the vacuum pumps went bad, if you have a mercedes or bosch part number i will see if i have one, i can either send the whole pump, or just the board. send me an email to [email protected]
