Question about 2001 Lincoln Town Car
Replaced blower motor, resistor, fuse, relay, and ATC. There is one thing I can't identify. It's in the wiring just before the blower motor. T-shaped, two pin connector, and top is filled with a black plastic/bakelite. I can't get any fire across the pins. Any idea what this component is? Thanks.
Sounds as if this is a connection that isn't required on your model,the manufacturer uses the same wiring harness on many different models so to keep costs down , the connector/s not required are blanked off hence the plastic/bakelite covering

it is called blower motor resistor , should be close to blower motor , you will see a plug type connector with two screws , remove the screws and there should be a resistor inside the cover for the motor, swap with new and reassemble

it is located on the heater box where the bolwer moror is there will be two screws holding it on the housing, look on the passenger side under the dash it will have 3 to 5 wires connected to it depending on the type of temp controller.

The Blower Motor Resistor is a common problem in your car but not for the problem you describe. When the Heat/AC won't blow on all speeds, the blower motor resistor is at fault. When air won't blow out of vents, bi-level, or floor the problem is the blend door actuator. This is vacuum driven and diverts the air to where you select. When air will only blow from one place (usually the defrost) then the blend door actuator is the problem. This can sometimes be corrected if there's a vacuum leak (usually under the hood in front of the passenger you'll find the vacuum line and can trace it backward to find a leak). If no leak can be found, the blend door actuator itself is defective and needs replacement.

it's most likely the blower resistor, which is located under the hood on the passengers side in the evaporator case. if you have manual a/c heat control this is a cheap fix, if you have auto temp control it is a very expensive part [around 200.00] good luck

Blower Motor not working for all speeds or not at all.
What does it take to get air to come out the vents?
1. Power from the battery or alternator, wiring thru a fuse and possibly an accessory relay to the switch
2. Switch and wiring to channel voltage to the appropriate resistor corresponding to the desired speed
3. Resistor set to reduce voltage to the blower for settings less than high
4. Final wiring to blower and blower itself
Because there is usually no relay between the switch and the resistor, all of the blower current runs through the switch. This sometimes causes the switch to overheat and fail over time. Depending on how the switch is designed, the failure may allow multiple currents to run to the resistor pack, and this may in turn cause the resistor pack to overheat and fail. An example of the circuit I'm describing is shown below:
Note that if the above switch was to contact both terminals 2 and 3 simultaneously, there would be more current than the resistor pack is designed for. This can burn the resistors and/or blow the thermal breaker. Also note that if the resistor pack fails, the blower can still run at full speed.
Troubleshooting: The last sentence above is a clue.
If your blower is working only on high speed, the likely cause is a failed resistor pack. However, because of the other discussion above, you should also troubleshoot the switch to see if it is the reason the resistor pack failed.
If the blower does not work at all, odds are that the problem is the fuse, relay, or the motor itself.
Repair: The resistor pack is installed in the air stream of the system to help cool the resistors. It is usually accessible from under the dash on the passenger's side or sometimes from the engine compartment along the firewall. It is identifiable by the connector with several wires coming out-some going to the switch and some to the blower motor. The resistor is replaced by unscrewing it from the duct and reinstalling the new resistor pack.
The blower is usually accessible from above the passenger
