I have an Acura 1.6 EL, 1998 and the Heater/AC Fan blower does not work on the first 2 speeds. Just before this happened there was a loud humm from the fan. Now no humm and no fan at first 2 speeds.

I opened up the glove compartment and I can hear the motor humming at the first 2 speeds, it is a quite humm (thus getting power, but may be not enough current).

Any ideas?
