Seems that you have a problem with your PSE-pump, it´s located under your rear seat, on the right side.
Quite common problem on these cars it seems...
Had the same deal on my ´97 S420, turned out it was the motor that was "gone fishin´". Replaced the motor (the entire PSE pump unit costs around $4000 over here, so it was worth a try), and everything was working fine again.
If you have access to a vacuum-tester of some kind, start by checking the lines for leaks before replacing fully working parts. You can also remove the PSE-pump and connect 12V to it to see if the motor runs.
Might also be worth a try pulling out the fuse and put it back in, but I don´t know if this works for this problem (like it sometimes does when the door closing aid stops working).
