HVAC Fan worked intermittently and would stop. I would tap on the resistor housing and it would work for awhile then become spastic and intermittent then stop. I replaced the Fan Blower Resistor. The fan works but is still spastic and intermittent. What needs fixed?
Sounds like the blower motor needs to be replaced.
SOURCE: Lincoln 2000 town car Blower doesn't work at HI-MED-LOW speeds...
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
SOURCE: Where is the blower resistor located on a 94 lincoln town car?
On the firewall by the back of the passenger side cylinder head.
SOURCE: 1999 town car blower motor resistor.....maybe?
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.
SOURCE: a/c fan no longer operates.
The control module for the blower is under the hood just below where the two heater hoses go into the firewall. It is straight behind the passenger side valve cover,
SOURCE: a/c heater fan works intermittently - i leave it
These climate control systems are very complicated. It could be a lot of different things. Usually it is a relay. When it doesn't come on the next time, take your hand and bump under the dash on the passengers side under the glove box. If the fan comes on then it is your relay. Sometimes the relays don't close to provide power to the fan motor. Usually this is the problem.

Reasoning the problem $57.00 for a blower motor after spending $210. for a resistor and installation (which did not solve the problem) seemed the better risk before possibly having to spend $600.00 plus to have the in dash control unit replaced. It seems replacing the fan motor was the fix for the problem. It is upsetting after to have already spentthe $210.00. It was my beleif as well as several others that if the fan motor was working (even spastically) that the problem must be elsewhere. The resistor was not an easy install wipers, cowling and hearter hoses needed to be removed in order to get to it. Even then because of the angle and position it was difficult to replace. (I did pay for this installation) However the fan motor was reletively easy to replace with the knowlege that the wiper fluid bottle needs to be moved out of the way and the wheel well needs to be forced down and out of the way for the fan motor replacement. I was able to do this repair myself. It seems the intermittent and spastic blowing was in fact the fan blower motor. Thanks for all your input guys. This one seemed to defy logic in spite of all the advice.
