My 2000 Lincoln towncar(signature series) a/c suddenly stopped working, no air thru vents not even outside air. fuses//relay all good. I hear the motor kick but no air thru vents????
not sure if I am repeating myself here. but I checked fuses and relays. all good. I can here the motor running when I push max air w'the air to come thru vents 1/2 speed. nothing. when I go to just outside air same nothing thru vents.
Check the blower once more to be sure it's working. Then check the switch that moves the defrost to vent to floor to see if it's getting vacumm to move if not then I would need more info. (replace the fuses to make sure that they ARE good) I have seen a fuse look good when the part you could not see was blowed. So do these things and let me know. I hope it helped!
Or the blower controller, located on the firewall behind the valve cover, near a wiper arm on the passenger side. That was the problem with my car and if you tap it lightly it may jog it back into operation.
