Sorry, but all correspondence must go through this site. JA rules.
There isn't a big problem with the rear resistor like there is with the front. It would be best to perform a voltage check at the resistor and motor to determine what is going on. This will determine if in fact the resistor is bad or the motor or something else. They are located behind the passenger side rear panel.
As far as the bulbs in the overhead go there may not be a replacement bulb available. Did you check both aftermarket part stores and the dealership? I'll try to find the removal procedure for the overhead and get that to you. My dealer site isn't working this morning for some reason.
Could you provide some specifics as to where the rear fan and resistor are located so I can take the readings, I never really looked for them. Do you have any specifics on what voltage measurements should be obtained and the proper test points?
Getting the overhead console out, would allow me to possibly find replacement lamps from somewhere.
The voltage will be battery at the connector to the blower resistor.
Here are the instructions to remove te overhead console.

David,
Sorry, I was having computer problems at home and could not get to my email there. That was why I was asking for you to have the response go to two different emails, if possible, will your site allow you to respond to my work email? XXXXX@XXXXXX.XXX
Your reply on the overhead is fine and thank you for that.
I was also looking for more information on the location of the rear resistor, the blower fan, and how to remove the fan.
If the rear blower works like the front, then when the resister goes bad, it would only work on high blower, correct? That being the case the fuse and relay for the rear blower appear to be OK. I swapped the rear blower relay with the accessory relay and it still didn't work. Most of the relays seem to be the same part number, so I assume they are interchangable. Switching them made no difference.

Looks like the picture I sent was a no-go. I'll try a different method.

This is at the right rear quarter panel. If you can peel back the panel to get to the resistor you won't have to remove it fully. So some of these steps aren't needed.
Even though some of the Dodge Caravan's around my year allow the rear AC fan motor to come out towards the interior, mine comes out toward the body requiring removal of the entire coil box assy, so I had to take my car into the dealer.
I took everything apart, but there was no way to get the motor out and I called two other techs I know and they both confirmed that some require disconnecting the refrigerant lines to get it out.
I am dissappointed that you made no mention of this. Even my Haynes manual had one picture showing the blower motor facing inwards for easy removal. that must have been a pre - 2001 model.

My original question included procedure to replace both. When I open up the panels, I tried to turn the motor and it was frozen. I was able to break it loose, but the bearings were shot. I had purchased the new motor, so I plugged it in and the new motor worked fine indicating that the resister and controls were good.
I was very frustrated that I couldn't removed the motor. I would not have wasted the time taking everything apart had I known in advance that you have to discharge the system in order to remove and replace it. I don't have the equipment necessary to do recovery and recharge.
Here are your original questions:
I have two questions on my 2001 Dodge Grand Caravan ES. 1. The rear AC fan is not working at all from the front or rear controls, no air. Is the resistor the most common failure, where is it located and what steps are needed to remove it. 2. The backlight for the control buttons in overhead console and some of the central console are burned out. I have been told that they are not replacable and to order a complete unit which seems unusual. Can the lamps be replaced and removing the overhead console seems difficult. What is the procedure?
Had I known you wanted to work with the motor as well I would have provided you with those steps. I had no reason not to.
My first test for any electrical issue is to make sure there is a good ground and power to the component is question. So access to the resistor and motor connectors would be the first step. Once power and ground are established, then you look at actual component failure by process of elimination.
Sorry it was in my June 6th reply that I mentioned -
" I was also looking for more information on the location of the rear resistor, the blower fan, and how to remove the fan."
it really doesn't matter now, just had me messed up when it happened.
Thanks,
