2000 caravan,need location of rear ac blower switch resistor.

you possibly have a bad blower motor resistor. It is located behind the glove box. First check to see that there is power to the blower motor on the black wire at the blower motor. If there is power than ground the dark green wire at the blower motor. if the blower motor runs at full speed than the resistor is usually the problem.

you can also check for continuity between the dark green wire and the dark blue with grey wire at the resistor. Note where those two wires are in the connectors. remove the connectors from the resistor. check for continuity on the pins in the resistor where those two wires where attached. If there is no continuity than the thermo fuse has blown in the resistor and the resistor will need to be replaced.

The resistor for the rear blower is bad. It is by the blower. And I believe yours is located at the rear of the vehicle on the drivers side. Behind the panel.

if you have cold air in the rear then it isn't the a/c compressor. if no air comes out of the front vents the it is either the blower motor or the blower motor resistor.

The most common problem would be a bad blower at which you can test for power at the motor connector with a testlight, the other most common problem is the resisitor ,theres one for the front blower and one for the rear blower, you may have a bad resisitor for the rear blower this resistor is located next to blower.theres also arelay in the fuse/relay box next to the battery under the hood,the best thing is to start testing for ower at the switch and work your way to resistor, i think you will find a bad resistor to rear blower motor.heres a complete wiring diagram of the whole front and rear heat and ac unit, everything is labeled good luck.

I think your blower motor resistor is bad. The link is a YouTube video showing the location and how to replace this resistor.
Replace Blower Resistor for 2000 Chrysler Town and Country

It is the blower motor resistor located behind the dash glove box. Take the glove box out to access and change. It is mounted on/into the fire wall.
Very easy to access, remove and install a new resistor.

You need to install a new blower motor resistor. It controls the speed and load on the blower motor.

Hope this helps

FRONT RIGHT REAR OF ENGINE COMPARTMENT NEXT TO RH STRUT TOWER

The blower motor resistor is located on the dash panel, on passenger compartment, right behind the glovebox. The resistor is mounted on a plate assembly that can be removed as shown on picture below:

Good day
If it's only running on high sounds like is the blower motor resistor. The resistor is located in the AC housing behind the glove box, a very easy to replace. the resistor controls the speed of the motor. after you replace this you should not have a problem

hope this helps
