blower motor not working on 2002 Mercury Grand Marquis

blower motor is good and fuse is good could it be a relay or resister and where are they located

Asked by for the 2002 Mercury Grand Marquis
Does your vehicle have "automatic temperature control" - the digital set temperature? If so, the failure is likely an issue with the blower speed controller.

If it's manual temperature control, it's a resistor issue.
