96 lincoln town car ac fan doesn't blow

Broken vacuum line from the engine to the controller.

Something broken stay only on cold !!!

I'm no expert when it comes to your vehicle. However it sounds to me as though there may be a vacuum leak somewhere causing the HVAC door that controls the AC/heat to be faulting to the 'hot' side.

Drive the car up to 55 MPH with the AC on. Making sure there is no vehicles close behind you,completely let off the gas pedal and see if it starts blowing cold air right after letting off the throttle. If it blows cold, then it's probably a vacuum leak.

If it doesn't blow cold then it could simply be low on freon or a partially clogged filter in the AC line.

Hope this helps.

To fix the AC unit which blows hot air all the time. Seems like you have a small leak in the system or the AC compressor has gone out. Suggest you try recharging the unit. Make sure you have the correct R-22 or 134A freeon. If this work for a few days then have the leak fixed, if this doesn't work replace the compressor. Check Ebay for the compressor i obtained one for $100.00. Cost $450 at Auto Zone.

Sounds like the heater and a/c blend door actuator. It is located under front center of dash below windshield. Dash must be removed to replace it. I've done it several times.

I have a 1994 lincoln town car executive series. Can the driver bucket seats, passeneger bucket seats and the rear bench seats from a newer model 96 or 97 e used with a 1994 LTC?

indicates a problem in the fan in front of the condenser
possible loose connection , bad relay or bad ground point

A common Ford/Lincoln problem it's the blower motor resistor. They're not very expensive and aren't too difficult to install. I hope this answers your question.

Bad Ac/Heat Blend door

if you have checked the fuse and they are good and there is power going to the blower replace the blower you should be able to pick one up at a good salvage yard at half the cost.
