Mercedes: A/C Blower Stopped Working, e 320, blower motor

Question
The a/c blower in my 1998 E320 with 79,000 miles stopped working.  Neither the heater or defroster blower is working also.  The fuses checked out OK.  What could be the problem?  Atlanta, GA

Answer
What do you have?
E 320 Sedan
E 320 Wagon
E 320 Wagon 4-Matic
E 320 Sedan 4-Matic

The blower motor and blower regulator are mounted together, under the passanger dash, they generally fail together, however you may be fortunate, remove the motor and test it, if it is good 90% chance the regulator is bad.
