It could be the relay
crown Victoria blower not working and head lights.
The blower is a multi speed unit.
If by scrub you mean drag or cease, then it is possible that the calipers need to be replaced.
on the passenger side firewall
right adjacent to the flux compassetor.
Check/ replace the blower resistor. Located in the duct work under the hood. Follow the wires from the blower motor to a plug on the duct work. This is the resistor
My crown vic 2000 when ac runing that time fac not working pls help me
most likely cause is one of three relays for the blower motor, usually located on the firewall under a plastic covering or near the battery If you do not use the blower motor very often like your car sits for a few weeks mositure gets in the blower motor and causes rusting which can cause your blower motor to lock up. Best suggestion is to run you air conditioning unit on high for about half an hour every once in a while.
You can unplug the blower motor and run a jumper wire to test the blower motor. If it is grounded through the plug you'll have to run a ground wire to it also. Blower Motor tested good. The Problem was the Blower Motor Controller which was located on the firewall just below the Heater Hoses. Thanks for responses to question.

There are two possible actions: 1) Replace the speedometer head assembly, because that is where your problem is. 2) Ignore the broken odometer and forget about it. The speedometer and odometer are one assembly. The same input that drives the speedo also drives the odometer, so you have a problem in the head itself.
