It is going to take mw a better part of a week to finish this project.

I have 2 modification ideas.

W124 climate control blower motor modification.

1. Using the fader control position to install a variable resistor for infinite speed control. Both mods will only work on climate control systems that are working. This will not make your fan work if it is not currently working nor will it correct improper vent or heating/cooling operations.

2. Sacrificing the Auto button for a medium speed or include a small switch that will allow both that can be installed in glove box or under dash..

I would expect a cost of around $20.00 - $30.00 for a full color instruction manual or CD with lots of pictures along with all the components needed to do this modification.
