Purchased a 1991 560sel this weekend. The interior is in excellent condition. Upon closer examination of the seat functions, i found that the rear seats only reclines on the right side. The left side doesn't move at all.

Any tip on how to troubleshoot this issue? The rear left window also do not close all the way, leaving a good 2 inches opening that felt loose when I close it up manually using my hand.

The OEM radio doesn't seem to work, although the antenna does extend upward when I turn on the power. The LCD screen is shattered for some reason. I will be switching out the head unit anyway, but this 91 560sel does not have an antenna switch on the dashboard. Very strange.

Appreciate any help you guys can offer.
