Interestingly, the Haynes Manual (#30011) I bought several years ago covers 1996-1998, but on the http://www.Haynes.Com web site there is a notation that the current version of this same manual number covers "all models '96 thru '02 Does not include information on All-Wheel Drive and alternative fuel models. Includes Grand Caravan". Maybe the current version (if there is one) of Haynes Manual #30011 is more helpful for your purposes... if an updated manual really does exist, hopefully Haynes has done a better job this time describing and troubleshooting these types of AC/Heating Blower issues... the manual I have is woefully inadequate. On the http://www.Chiltonsonline.Com web site, their current manual only seems to cover 1996-1999 - no new millennium Caravan stuff at all. Sorry I cannot be more helpful on the location of the Resistor Block in your '01 GC. Last edited by HeadlessHorseman; 12-29-2005 at 09:31 AM. |

Re: 1996 Dodge Grand Caravan LE AC/Heater Blower, Relay and Resistor Block Problems 101
Hey Parky50, how did you make out with locating the Resistor Block on your '01? Has anyone else out there with an '01 had a problem locating the Resistor Block and, if so, where is it actually located?

1.) What is the socket NUMBER of the 40amp fuse for the Blower Motor Relay of your '01 (this number is different for 1996 [Socket #3], 1997 [Socket #7] and 1998 [Socket #21]), and 2.) Where is the socket LOCATION of the 40amp fuse for the Blower Motor Relay of your '01 (my '96's socket is located in the Power Distribution Center [PDC] under the hood, driver-side). Thanks in advance and Good Luck again! |

I tried looking again on the firewall, just can't seem to see anything in there up high or lower with three wires running into it... There appears to be some kind of cover that is mounted up high on the firewall and it appears to go over the wiper motors and such. I will take that off next to see if that Resistor Block is hiding behind there. I tried looking on the blower motor too. There was a little black box that was held on by two screws and had a set of small wires running into the back... I thought I was going to luck out there... It was a little motor assembly with gears in there... I'm guessing that would be the motor for the "Blend Door". I put that back together and installed it back on the blower motor. As far as the Blower Motor Relay... It is located in the engine compartment in the IPM - Integrated Power Module right next to the battery. I'm not sure of the socket number but I was able to scan a pic of the cover and labeled them to post a pic on the forum. I'm unable to attach anything so I could e-mail you HeadlessHorseman if you would like to see the exact location of the Blower Motor Relay. Thanks, Mike

Yippy !!!
I found the Resistor Block located directly behind the glove box on my 2001 Caravan. Simply open the glove box and push in the two tabs on each side to open the door all the way and there it is !!!
Part # 4885583-AB RESISTOR 8035022 Heater Blower works like a charm now !!! Thanks to all for the information and direction...

Re: 1996 Dodge Grand Caravan LE AC/Heater Blower, Relay and Resistor Block Problems 101
What a great thread. You guys are tops.
97 grand caravan blower problem- My better half's blower motor quit completely. I replaced it and it worked great! I was a hero. 30 minutes later she went on an errand and it quit. I'm not a hero any more. I new enough to check the relay located under the hood and the fuse and found they appeared to be fine. i.e., coil was closing the contacts and I had 12 volts on both sides of the contacts which comes from the fuse. I read a couple of threads elsewhere before joining this forum and zoned in on the risistor. While trying to get the connector off and getting very frustrated, my wife came out and turned the switch on and it worked, for three weeks. It has quit again, completely! I replaced the resistor and nothing works. I swaped relays. Nothing. I bought a Chilton's book with wiring diagrams and see that 12 volts should be on the blue wire at the fan motor all the time when the ignition switch is on. The speed switch and the resistor work on the negative ground side of the circuit. I don't have 12 volts at the blower. The wiring diagram shows a straight wire from the relay (where there is power leaving) to the blower connector (where I have no power). Does anyone know where there may be another connector in between which may be compromized? Thanks, |

It is possible to have 12 volts going to your blower motor and not enough amps to turn it because the relay no longer closes the circuit with good contact. Remember, this circuit is rated for *40 amps* and that's a lot of juice. Normal use causes relay contacts to become burned and pitted over time. You said you checked the relay under the hood... are you sure that's where your Blower Motor Relay is located? I was under the impression that this relay was located under the dash, driver's side, behind the Junction Box/BCM - that's where my Hayne's manual says it's located for your '97. I have no idea what relay you were checking. |

Thanks for the responce! This is splitting hairs... production date = 7/96 - title and owners manual 1997. The PDC is under the hood with the relay at position 5, fuse at position 3. Power for relay coil comes from junction box under dash, fuse 12 (10 amp).This is switched on by ingnition switch. 40 amp fuse no. 3 (PDC) powers (hot all the time) the contacts in relay which when the coil energizes, supplies the relativly large(40 amp current potential) dark blue wire which leaves the connector no.1 under the PDC, straight to blower connector with constant +12 volts with ignition switch on. {this per the diagram in Chilton's} <<new info>> The dark blue 12 volt supply wire leaving the PDC travels through the firewall in a harness on the passenger side of the steering column and goes through a large multi-wire connector (possibly for all under dash componants) which is located under the dash above right knee when driving. >>> This connector location info supplied by friend's friend (dealer technician) as I was writing initial post.>> I just checked the connector under the dash and BEHOLD! Apparently the previous owner had a problem with this wire in this connector and someone (explenatives researved) patched this dark blue wire, possibly a 10 ga, with twisted wire junctions and a 16 ga wire around the outside of the large connector. One of the twisted junctions had melted in two. I will replace the patch wire with proper size and solder solid and insulated with shrink tubing. (I did jump it out and blower works) We have had this vehicle for 3 years and have had great service. I probally should consider a fire extinquisher! too blessed to be stressed and off to slay other dragons.... |

It's interesting that you say the 40amp fuse is in socket #3 in the PDC... my Haynes manual says it's in socket #7. But then, you also said that the production date of your '97 was 7/96. My '96 was made 2/96. What a difference five months makes. Thanks for sharing all of your great information and research... I'll work it into the original post (and make you famous )! |
