With the heater box out, it only takes about five minutes to change all the vac servos. It takes 16 hours on most W124s to change them otherwise, since one can only be accessed by splitting the heater box, and that requires removing it from the car.

Just a hint to anyone getting (or doing) an evaporator replacement on a W124 chassis -- go the extra $200 and replace ALL the vac servos while you are in there! Much less pain than replacing them a couple months later when you decide they are shot! Also the right angle connectors on the switchover valve, too -- much eaiser out of the car.

It figures that the evaporator that fails commonly is the one that requries the most work to get out....
