1. Disconnect negative battery cable. On 2000 Dakota, blower motor relay is located behind instrument panel, inboard of glove box. See Fig. 1 . On 2000 Durango, Ram Pickup, Ram Van/Wagon, front blower motor relay is located in Power Distribution Center (PDC). 2. On Ram Van/Wagon, front high speed blower motor relay is located in engine compartment, on top cover of on inboard side of heater housing assembly. See Fig. 2 . Rear blower motor relay and rear high speed blower motor relay are located in a connector bracket that is secured to back of rear A/C-heater unit cover. See Fig. 3 . 3. On all models, remove suspect blower motor relay or high speed blower motor relay.

Using DVOM, check for continuity between terminals No. 87A and 30 of relay. See Fig. 4 . If continuity does not exist, replace relay. If continuity exists, go to next step. 4. Using DVOM, check for continuity between terminals No. 30 and 87 of relay. See Fig. 4 . If continuity exists, replace relay. If continuity does not exist, go to next step. 5. Measure resistance between terminals No. 85 and 86 of relay. See Fig. 4 . Reading should be 70-80 ohms. If reading is not as specified, replace relay. If reading is as specified, go to next step. 6. Using jumper wires, connect battery voltage to terminal No. 86 and ground terminal No. 85. See Fig. 4 . Check that continuity exists between terminals No. 30 and 87. Check that continuity does not exist between terminals No. 87A and 30. If continuity is not as specified, replace blower motor relay. If continuity is as specified, relay is okay.

BLOWER MOTOR RESISTOR 1. Disconnect negative battery cable. Disconnect blower motor resistor harness connector. Using DVOM, check for continuity between all blower motor resistor terminals. If continuity exists between all terminals, go to next step. If continuity does not exist between all terminals, replace faulty blower motor resistor. 2. Check for open or short in circuits between blower motor resistor and heater control panel. Also check for open or short in wire between blower motor resistor and blower motor. BLOWER MOTOR SWITCH 2000 Dakota, 2000 Durango & 2000-01 Ram Pickup 1. Remove Power Distribution Center (PDC) cover. Using DVOM, check for battery voltage at PDC fuse No. 5 (40-amp) on Dakota and Durango; PDC fuse No. 12 (40-amp) on Ram Pickup. If battery voltage exists, go to next step. If battery voltage does not exist, check for open in Red wire between battery and underhood PDC. If Red wire is okay, replace underhood PDC.
