Stump the Board! Mulitple issues, wipers, radio, phone, and keyless system

Let me start with saying these issues come and go with no rhym or reason.

1. With the wipers turned off they will start running fast and to turn them off I just turn the nob once then they stop. Sometimes even doing this does not work and I will be driving down the road on a sunny day, which doesn't happen very often, with my wipers running. But since the new issue below showed up my wipers are working great.

2. My keyless entry system stop working. So then I used the mental key and went and open the trunk which I guess resets it. Now that is working fine.

3. Since the reset of the keyless entry my radio now has no sound but my wipers are still working normally. Mute button show up on the screen when it is pushed. There is just no sound coming from it.

4. I kept the Star Tac in its cradle and on but now it will not power on since all this happened.

So any suggestions on how to get the volume back onto my radio, while keeping the keyless system working, and not have my wipers go on whenever they like?

Thanks for the help!!!

this could be a sam problem.

Given that you've had a lot of rain, have you had any water intrusion?
SAM is signal acquisition module.

Basically, the s class is unlike many other cars that have separate computers for each electrical item.

Basically, on the MB the SAM is where a bunch of different inputs are wired into, and it controls all of them through the Can-Bus.

So if say one were to get wet, a lot of odd problems can occur.
I believe under the front seats for the front sam.

I believe its the passenger side, but Im not certain.
