1982 300d Window relay?

I am troubleshooting an intermitent power window issue. Replaced the window switch on the driver's side and seemed to solve the issue. Later all four windows did not work. Tested fuses in fuse box (OK), checked contacts at both driver and passenger switches. Is there a FUSE RELAY or other item I should check before tracing the entire wiring system? I am assuming that such a relay exists...
Many thanks. --- Chris Konik

a/c compressor leaking at line connections

I am having trouble with the A/C compressor on my 1984 300D.
It appears that there were several hose-block connections and compressor connection configurations.
I ordered a new compressor (for a different car). It came with the adapters and instructions. Unfortunelty, I'm having trouble understanding them.
I can't get the compressor to stop leaking at the hose connections in the rear.
