Re: 2000 dodge grand caravan
It is located behind the glove box, which has to be removed to get at it. Once it's removed, you will see a small square like panel with 2 bolts attached to the hvac casing, and wire connections.you might need a screw driver to gently pry it out, while turning it sideways. Hope this helps.

The Blower Motor Resistor is located behind the glove box on the dash. Remove the whole glove box to access. The Resistor is mounted against/sort of into the fire wall. 1. Disconnect the negative side of battery. 2. Disconnected the Electrical Connection to the Resistor. 3. Remove the bolts/screws. I believe they have 8mm heads, there should be 2 of them. 4. Replace with new one/Replug electrical connection. 5. Reconnect the negative side last. 6. Test System before putting the glove box back in!
The Blower Motor is easy (compared to $1000) to remove and replace.
Check owners manual for location of heater blower motor front,check with a test light,if it's good locate blower motor under glove box and test the two wires for power when switch is turned on,if power is present motor needs changed.if no power check blower motor resister.
The blower resister is located very close to the blower motor,behind the glove box,in that ares.The resister controls the speeds of the motor.It will be mounted with two screws,and have about 7 different wires going to the plug in.The resister is mounted on the out side,but actually goes inside the blower box,so it can be cooled.The reason for the resister failing is the blower motor.The blower motor may sound fine,but it is drawing to many amps,and is burning the resister out.
If the blower motor is not working the most likely cause is the blower resister, but you must replace the blower motor also because the resistance build-up inside the motor is what damages the resister.
in my 2004 grand caravan it's behind the glove box and left of the blower motor. disconnect the wires first then remove the 2 screws to pull out the resistor unit. First make sure you have removed the negative of your batterie. I had the same pm that prevented the blower motor to operate in any speed. I hope this will help
