If the fan will not run on ANY speed in your Grand Marquis, the problem is most likely NOT the control switch.
Check for power and ground at the blower motor connector. If power and ground is present, replace the blower motor. Otherwise, the problem is most likely a failed blower speed control module (VERY common). The blower motor speed controller is located in the A/C evaporator housing just below the heater hoses.
Note: It is also common for a bad blower motor to CAUSE the controller to go bad. You MAY have to replace BOTH.
In most cases this problem is caused by the rotating ribbon circuit contact under the steering wheel having a broken filament, the part is known as a clock spring contact, u will need to properly disarm the airbag and remove the steering wheel to access the part. WARNING: Failure to disarm the airbag system can result in an unexpected Airbag deployment and possible serious personnel injury disconnect the battery 30 minutes prior to start of work.
