1999 Mercedes E320 blower intermittent

Doctor's wife's car with only 40,000 miles.
Blower works sometimes.

Removed two panels under right side glove box. measured 12V in both large and small red wires going to motor and regulator.
Both voltages still present when regulator failed after running awhile.
Replaced regulator in pic and problem solved.

This is the new improved style according to the dealer. Looks to me like it is still failing prematurely. Removed unit was fairly warm to the touch. Cost of this unit was $140.00 from local distrib. and $240 from the dealer.

Be sure to come with a torx bit set to remove the screws. That and a phillips is all you will need.
