I just got a 1995 Caddy DeVille. The A/C works, I can feel cold air seeping out of the vents. The fan will not spin. I tested the fan using a wire from the battery. The fan will spin that way. What else could be wrong? The car has the Caddy climate controls.

I have changed the resistor 2 times for the same problem. Its under the hood behind the fan motor insulation. Mine burned because of fan motor frozen & stuck in the winter. Solution is to let the engine warm up before turning the fan on. Cheers, Brian
There should be a nozzle on the left passenger side that has blue for cold and red for hot so if there is a light on the nozzle all you have to do is turn it to cold if you want it cold. Caddy's have dual heat so you can change what you feel coming out push the nozzle in and the light should go off. Therefore making the car on the same hot/cold.
If the blower was working why did you replace it?
Heat is made by the engine, and then it is sent into the heater core and a fan, blower motor, blows heat into the car.
First - check that the coolant level is full. If not add MIXED coolant.
Then drive a few miles for the engine to get hot.
If coolant level is full, the thermostat might be bad, or the heater core might be plugged.
This may sound stupid but are the correct shocks and struts for air ride on it. I had a guy bring in his caddy with the same problem and the guy he bought it off of didn't want to pay for the expensive shocks and instead went with a cheaper pair without air capabilities. I put the right ones on and problem solved.
Blower motor resistor is most common ($20-$70) it controls the blower motor fan and speeds or fan relay fuse (usually under the hood) If it's not either then the blower itself is bad. You can pull the motor and apply 12volts to it to test, if it spins then the resistor.
