How do I check the climate control servo on w116?
I have a 1979 300SD that does not have heat in any mode. Every button works and does as it should though. I hot-wired the water pump that is on the servo, and the pump did spin. Do you guys know what else I need to check to see if it is the servo before I buy a new one. (probably used though).
