I just purchased a used park avenue. The a/c compressor works and the lines get cold, but the fans do not blow inside the car. They don't even come on. What could be the problem? The fans have been tested and they are good. Is the blower a module or relay? Help, Please.

Besides the "fused circuit for the fan, there is the switch (usualy not the problem), - also the "speed dropping resistor located somewhere within the air stream of the blower - (since it is what cools the resisitor)! It could still run on "high speed" with the resistor(s) burned out, - but it still requires power to the blower motor from the relay, --- relay "default" is supposed to be "high" when relay contacts are good, - (even if relay inoperative)! So you need to check the relay, and see if there is power coming into the plug for the relay!
This is a very complex explinaton, but it isn't really a complex system to check out, -- however keep in mind that you also have wires that could be broken too! It's kind of like a "chain",-- if it breaks along the way somewhere, - it is no longer efective to use!

The fans might have been good but the blower underneath the dashboard is blown. I have the same problem with my oldsmobile 88. Just go to a autoshop and get a blower for like 100 dollars or something.

Sounds like (Clicking) a Bad Fuse and/or Relay that is Bad because of Shorting Wires or Bad Blower Motor! After the Motor has been running for a while does the Blower Housing Feel Hot? "Bad Motor" Replace! Could be the Switch but it Sounds more like the Motor.

There are fuses, relays, switches, wiring, and a blower resistor.
Get it diagnosed by a professional auto technician.

Check the fuse box first. If the fuse is good it could be a bad switch on the dashboard. How did you check the fan?

DO NOT run the a/c if the fan is not running. The system will freeze and cause damage.
