AC Blower Motor stop working all together
99 E320 4matic wagon
Drove home from work - fan was working.
Next day - turned on and nothing.
No previous signs of going out or failing. Has worked fine up until now.
Checked both fuses under hood (driver side) #4 & #7 (Climate control/AC blower motor )
Also checked fuses under hood on passenger side inside compartment (maybe climate control box?) Held in place by 4 screws.
Is it normal for a MB blower motor to simply stop working?
I feel COLD air from the vents when moving as air is being sucked through by window being down a inch but fan is not working/blowing air at all. Climate control shows fan at all speeds on display.
Any tips are appreciated.

Sounds like a bad blower motor regulator mate...

that's what I was thinking, but wasn't certain . guess I can bypass the motor by lead wire from extra power source (batt) to see if it works. Thanks for the reply
