1985 Mercedes 500 SEL
Cruise Control Actuator buzzing, Relays Hot
Does anyone know if it is normal for a 85 sel Cruise Control Actuator to have a buzzing sound, like a little gear turning, coming from it with just the key turned to the "run" position? Also is it normal for relays "A" (seat control relay) and "E" (power separation relay), located in fuse box under hood drivers side, to get warm with the doors left open and get very warm to hot if the key is in the "run" position? The relays have been like this for years, but no smoke or shorting, or blowing fuses.

Thanks, Dan

Hmm
The buzzing sounds like a bad ground.
