I have two questions for you guys out in Mercedes land, I need a exploded view of the mono heater valve where all the spacers and parts go, I have replaced the plunger assembly maybe 5 times over a 30 years period but this time I dropped some spacers and parts putting in the new plunger. And one other question what is the function of the heater air temperature sensor not the one on the dash but the one close to the heater core? Thanks for any info

The epc doesn't show any exploded views, but there is a wave washer, at least, where you'd think it should go.
