I have obtained a reclaimed duo valve for my 1995 W124 E300D. Its the right one but before installing it I want to verify its working. Is there a procedure for doing this on the bench.
It has two terminals , one with 3 contacts which I think operate the two solenoids. The other with 2 contacts which is on the small pump build into the duo valve.
If there is a simple electrical test I can do that would be great. My existing one isnt shutting off properly so that there is still warm air coming through even when the controls are hard over to blue.
help appreciated.
thanks
