2001 Town Car - Blower quit Working

The heater/air conditioner blower motor quit working. COnsequently, I have not heat, a/c or defrost, except for the minimal amount that sort of "floats in" as the car is moving...

Any ideas where to look???

Check the fuses inside, AND in the power distribution box under the hood.
Testing the fuses may be required, it's not always visually evident they've blown.

Also in the power distribution box are master relays, I don't feel like looking it up, but one of those may be related to the blower.

Another good possibility is the blower motor controller on the dash, just BELOW the passenger side cylinder head on the firewall. THese are a known weak link, sometimes you can solder them up, $50 buys a new one from your dealer...
