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

[Taxilady88]

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.

I had this issue with me and it was a faulty part-
NAPA part I went through 2 that were bad in 2 weeks. I went to the OEM dealer and it now works fine for 2 months

01 Grand Caravan. First my resistors were blowing so after replacing 3, I also replaced the blower motor and vacuumed out the filter. Since then, 2 blower motors have also failed. Today it is -20 C outside and I have no blower. Brrrr ...now what should I try?

On my 2002 Dodge Grand Caravan, I replaced the thermal fuse from Radio Shack as recommended and it worked like a charm. The part number is 270-1320 and costs $1.99 (price has gone up slightly). Here's a picture of the part.

I disassembled the resistor assembly and soldered the new part into place, attaching heatsink clips to the leads to prevent heat damage.

Thanks for everyone's help. (Wife is pleased too.)

[Hanss]

You don't need to solder it, just use plyers and metal clips that are included with thermal fuse. Soldering is dangerous, it can damage your new thermal fuse.
Good luck.

My van is about to need it's 3rd one in the last 12 months. The joys of owning a Chrysler product, lol.

EDIT 1/7/11

My van actually needs the pigtail replaced this time. Resistor is not the problem I am having.

[b1lk1]

Bumping this back to the top. After replacing my pigtail roughly first week of February I am now experiencing yet ANOTHER resistor failure. I haven't checked yet to see if the pigtail is roasted AGAIN, but I am going to assume it is. I guess I need to replace the blower fan and see if I can get this system to last more than a few months without failure.

[stryfe101]

well this is an interesting read...i've replaced the resistor pack once and still had intermittent blower function...recently everything died...the blower slowed down, dash lights came on, the whole shebang....anyway i'm get infinite resistance on the motor itself, and still getting resistance values on the resistor pack. time to take the dash apart and fix the motor...hopefully this will take care of the problem...been without a/c in both cars all summer...

Can anyone help me locate and provide directions on replacing the Thermal Cutoff Fuse on my 2005 Grand Caravan with auto temp control?
