420SEL no power to blower motor
 

If I dont get power to the blower motor, and I have a good fuse, are we suspecting a bad pushbutton controller or could it be the electronic blower motor fan speed controller? 1989 420 sel

fuse
 

there is a flat metal fuse under the hood some have broken and yet when you hit a bump it reconects making the unit run itermitently, or it burns out and you have no power. are you sure this is good?

Could only be the fuse, the module or the blower. I just changed the module on my 300E. The blower was stuck, needed oil, and probably over heated the module and burnt it out. I bought a brand new one on Ebay for $75. Works great now. The module is located under the blower motor.

No Power!
 

Just had this problem!

Thought it was a bad Climate Control Panel but it turned out to be a the electrical part of my ignition switch. Wires got too hot, melted my fuse holder and burned part of my ignition switch. Result: No power to the blower! New part solved the issue.
