Repeat blower resistor failure

I had to replace the blower motor to get the resistor to last. Been almost 2yrs and no resistor failure after replacing it 3 times

I am confused. My blower is not working. We have tested the relays and fuses. We know the blower works. The only thing else would be the resister. I have read that on a 2005 Grand Caravan that it is next to the blower in the glove box area. Now I read there is a resister module under the hood on the passenger side. I am confused. Also I have gone to the Dodge web site and looked for a schematic for my van, but do not see one in the manual. Where can I find one? Any help would be so greatly appreciated.

If I am not mistaken up to 2000 the blower resistor was on passenger side under hood and in 2001 it switched to behind glovebox. Are you sure the blower motor is good? Also check the electrical connection on the blower esistor it could be melted. Mine blew the resistor 3 times replaced the motor and no more problems in 3 years it is an 01.

You have a blower resistor block if you have the manual temp control system. It can be accessed either from under the hood or from inside behind the glove box. You have a blower control module if you have the automatic temperature control system. It is accessed from inside up behind the glove box.
Are you getting power off the switch to the resistor block (or module)? I've read several reports of the control panel connector melting creating problems. Might check on it.

...and you have a schematic from ARRC.

Ok I had the same problem except the fuse didn't open, the resistor would burn open and I would only have the blower on high. After 3 resistor packs and a -25 temp outside,I got an idea why not add a heatsink to the ceramic resistor. So I beetled down to an electronics store and bought 2 small heatsinks made for the square SCR regulators, they cost a buck apiece and I used a thermal paste and a 8" length of insulated transformer wire and have them on the green ceramic of the pack. The paste conducts the heat and does not run and I had some varnished transformer wire sitting around anyway. I did have to bend the fins out a bit to fit into the opening but it was no big problem.
I will replace the blower motor in the spring but until then this is a cheap and easy fix that should take about 15 minutes to do

RIP I am thinking you sent me a link to a schematic for my 2005 Dodge Caravan, I know someone did. But I can not find the link and forgot to make more than one copy (blonde moment). One link that was sent was to a library and it asked for a library card which I did not have. Could you please send me a link one more time and I PROMISE I will make more than one copy. Thank you sooooo much. Really need it ASAP. Finally found someone to help me fix a problem I have but no schematic.
