No power on passenger side
Okay so lets start. I have some issues now with my 2000 S500 with 160k miles I was driving like 3 days ago everything was working fine then the blower motor stopped working completely. It was getting crazy for a while going on and off for few minutes and when I accelerated it seemed that it was blowing harder. Now it won't work at all on any speed so no ac or heat. Today while coming back from work I noticed that front passenger window won't roll down neither with driver switch or passenger switch... So I'm thinking to myself it must've been dcm as I had a problem on my driver side like that before so I bought used one on eBay and it works fine until now. I checked seat adjustment buttons and mirror on passenger side not working as well... so it already drove me nuts. Then while opening front passenger door and rear as well the automatic door closing stopped working on both doors but it works fine on driver side. Any guess or help what it might be the car drives fine. Oh I forgot the washer sprayer stopped working as well. Also I have that squeaky noise in suspension while driving up to 40 mph I replaced the rear control arms went to dealer to get alignment. Please help me guys as it really driving me crazy. There is no errors whatsoever. Thank you I really appreciate

You scanned the car with an SDS and there's no faults?
I'd say you have some sort of issue in the right side front SAM, on these cars it's split and the right side handles some stuff, the left side others. I don't know for sure without looking it up but I'd assume it feeds power to the door control modules as well, and probably the blower motor since it's right there.
