2000 Dodge Intrepid A/C won't work

The blower motor relay is energized when the Blower Motor Control is set to the High position. This removes the blower motor resistors from the circuit and battery voltage is then applied directly from the HVAC BLO fuse (RH IP Accessory Wiring Junction Block) to the blower motor though the relay switch contacts. The blower motor then runs at high speed.

HVAC Blower Controls Circuit Description
The blower motor is a variable speed motor. The motor operates at a higher rate when voltage is increased to the maximum level.
The blower motor resistors reduce the voltage supplied from the A/C FAN fuse (LH IP Accessory Wiring Junction Block) when the blower control is set at low and medium speeds (speeds 1-4). The blower motor relay is energized when the Blower Motor Control is set to the High position. This removes the blower motor resistors from the circuit and battery voltage is then applied directly from the HVAC BLO fuse (RH IP Accessory Wiring Junction Block) to the blower motor though the relay switch contacts. The blower motor then runs at high speed.

Will the wipers also work with the ignition off? If so, possible ignition switch problem. If wipers don't work, suspect shorted blower motor resistor or controller

Are the different speeds working on the blower or is this stuck on just one speed ??? It seem as if the relay for the blower is fused together in the on position an can no longer be controlled by the switch. If this blower is not a relay controlled unit then most likely the blower switch is no longer working.

It could be the the fan motor relay if you replace the relay and it still doesn't work then its the blower motor needing to be replaced.

try a new compressor or take it into the dealer

your blower motor resistor is bad, it is a small electrical component located next to the blower motor under the dash, held it with two screws.

Yes you car has something like a resistor but its called an ATC BLOWER CONTROL MODULE.Its under the dash on the pass side close to the firewall.

replace the blower motor speed control resistor, it is located near the blower motor..

if it is auto temp control the power module could be bad....if is regular style where you control blower speed the blower motor resister is bad

You need to replace the blower speed control module, it is behind the glove box near the b;lower motor.
