I am currently working on the AC on a 1984 300D and everything under the hood is fine, however, Im not getting a signal from the ETR switch.


I think it is located up under the dash somewhere, but I can't see it. Do you have to take off the front of the AC controls to get to it or can you go in from the Glove compartment side of the console. I know what it looks like, I just can't see it. I also think it's left of the Expansion valve.


Thanks in advance for anyone who can help, Happy Motoring !!

I must have missed something in the MB acronyms---WTF is ETR???

It is the A/C Temperature Sensor Switch..keeps the Evaporator from freezing up.

It's a plain ole "temperature sensor, evaporator"---is located about right knee high on the drivers side foot well---plugs into the evaporator!!

No...Im afrasid your wrong it is located on the butt end of the A/C temperature Control switch, which is no longer available and if it was would be over 600.00 Im told, by a tech at Peach Parts.
