Town Car A/C not working

Unread post by CindyB » Sat Jul 20, 2013 7:59 pm

2001 Lincoln Town Car - A/C stopped working. Replaced fan, still not working. Nothing comes out. Check fuses also. Any ideas?

so the ac may be working but your blower motor is not blowing air out of the vents, is that's what is happening? Or is the ac compressor not turning on too? Scan for codes tied to the Electronic Automatic Temperature Control (EATC). Then there are some tests that will need to be performed to test the blower speed controller

It sounds like the compressor is coming on but nothing comes out vents, blower was replaced already. Is there a relay maybe?

there is a 30A fuse, #2 in the central junction block behind left side of dash left of the steering column. It is hot in run. This fuse gets power from the pink and black wire out of the ignition switch. It send power through a brown and orange wire to the EATC (electronic automatic temp. control) blower motor. So, anytime the key is on the blower should have battery voltage power on the brown and orange wire. The blower speed controller supplies the ground. The blower speed controller gets all it commands from the EATC module. Before you change out a blower motor you should check to see if you have power (B+) and ground (B-) at the connector. using a test light between the two contacts of the wire harness with the connector unplugged and the fan speed turned on. The light should light up if the blower speed control is active. It should change in intensity as you go from slow to high. (though you may not be able to notice each and every speed the light would be for all the speeds) If the light does not come on further diagnosing of the blower speed control and the EATC module would be needed.

you could just ground the orange and red wire (with a fuse protected wire) to the blower (B-) to the blower motor while the key is in run (be careful this will be a big load and could make a big spark, if you have a remote starter switch it would be good to use it here) and the fan should come on high. The blower speed controller is it's own relay for the blower motor.

Few years back my car ac was also not working and I was also having the same issue then I got to know that my car ac condenser was not working and due to that my car AC stopped working so maybe its the same problem in your car also.

When car A/C doesn't works, its very irritating. A person does not feel comfortable to travel without A/C. There are multiple companies for Air Conditioning Maintenance Brooklyn, which provide reliable services for repairing and also to solve any other problem in it. So, According to me get it repair as soon as possible.

I would initially check on the filter. Next would be the compressors, if you dont hear anything once you switched on th AC like a tick sound, there is probably wrong with the compressor.
