W126, Climate Control

she drove as normal as you can expect for a 82 300sd that has been run hard and put up wet 300,000 + miles as odometer quit years ago. the 617 had alot of blowby and oil leaks [crankcase press] being the faithfull old girl she was she made it home and wouldnt fire next morning.checked compression below par, less then 300 psi in all 5 holes spining her with 24 volts my questions are #1 how does one check inj.

Dear Experts: Hope someone can help. Before describing the transmission problem. MY 1984 300SD has leaks from an injector. It is the hard line plus the hose. Don't know if that leak affects the tranmission problem I have.
