 Subject: Blower Motor dead
IP: Logged
Message:
I have a 1996 Dakota and the blower motor has just outright stopped working. I thought that I heard somewhere that there is a recurring problem with some kind of switch or relay affecting the blower motor's operation. If it helps, I do have Air Conditioning and vehicle is 2WD with the 3.9L MPI V6, extended cab.
The 30-Amp fuse for motor is fine, and the 4-speed fan switch has power (A/C Compressor even still kicks on if the A/C switch is on), but I haven't torn into the blower motor assembly yet because it looks complicated (but I'll do it if need be). I priced a new blower motor at about $60.00.
If anyone can enlighten me on bugs with the Dakota (previous model style, not current style) and blower motors, would you please reply to this message or else email me? I'd like to check out a bad switch or relay before tearing out the passenger side just to get a gander at the blower motor itself.
Much thanks in advance,
Rob J

Check the blower-motor resistor. This is the device that allows different speeds of the blower motor. It runs VERY hot when the fan is at low speeds. I have had at least 2 vehicles over the years burn out the blower moter resister.

Bruce is correct, it is a resistor bank, a set of wire coils that add resistances to allow multiple speeds from your blower. On mine, it is on the firewall under the hood. Last time I had a problem, it wasn't the resistor bank but the plug on the wiring harness that feeds current to the resistors that was corroded. I cleaned up the connector, male and female parts, and it works again. Always remember that at low voltages, you need high current to get the power needed to run your loads. And at high current, even the slightest dirty or corroded connection will cause a problem.

Don't forget though that if the resistor is toast then it will only have high speed. If no speeds at all then it could be motor or switch as well.

I never even knew that such a "crude" looking resistor bank controlled the various blower fan speeds! Thanks to your replies, I found the resistor unit on the passenger side firewall (it was pretty obvious with all the heavy wires on the connector).
I removed the connector, and saw some serious corrosion, so I sanded the rust off, put some lithium grease on it and reconnected it - no go.
Keep in mind I didn't even have HIGH blower power.
I pulled off the resistor bank (two screws), and found that the main power supply lead on the INSIDE of the whole assembly had corroded and come apart. I bent the lead and re-inserted it into one of the several other connection points available for that lead. I soldered it on and put it back on - VOILA! IT WORKED!
I tested all the speeds for about 20 minutes before returning the unit back to the firewall. It does produce quite a bit of heat! When I was sure it was not going to blow, I screwed it all back in.
Thanks for your help! I didn't even know this site existed before I need to find out about my blower motor. How appropriate is "DodgeDakotas.com"??? =)
Thanks again,
Rob J

Thanks for the post...My blower-motor resistor just failed & the repair was easy with the info...only cost 8 bucks & 15 minutes of time!!
Cause of failure: terminal rotted at elect connector (Green wire)

I have a 94 Dakota and fan doesn't work from speed control lever. Fan motor works when jumpered from fuse / ground to fan motor lead. I lost HI speed two weeks ago and now all speeds. I verified HOT at the fan motor lead / harness, but no power at any port in the speed control lever harness connector. Could this be the relay.

Thanks!
I had the same prob on my 1996 Dak, a a few months ago the blower stopped working, then about a month later it just started up again while I was driving - odd intermittent prob, i figured it was a short, turned out it was the resistors like you said! one is kinda burned and none are corroded though, it was loose and the single vertical blade on the right had become disconnected, works like a champ now! thanks again!

Bret, I'd be willing to put money on it. It's easy to fix. It took me about 30 minutes to replace both the block and wire harness on my '94. Both parts are available from you local Dodge dealer. The block is less than $10, but the harness is around $30. The block corrodes and then overheats melting the connector on the harness. The resistor block mounts on the firewall on the passenger side. Look for a plastic connector with about 7 wires comming off it. You can't miss it.

My kids '92 v6 A/T extended cab had the same exact symptom, and I did the same things, check fuses, etc.
I came to this message board while my dinner was in the microwave and found this post. I went out and fixed the problem in about 15 minutes thanks to your great post.
I pulled out the block and the bottom wire that crimps into one of the rows of sheet metal had corroded and broken. I cleaned it up and bent it again and put it in another hole on the crimped sheet metal.
It works great again, and if it breaks again I'll buy another one from the Dodge Dealer.
Thanks to all for such an articulate post!

You guys just saved me hours of agonizing diagnostics... Cleaned up the resistor - works great! I'm going to have a beer for each of you.

OH my ACHING BACK
I just spent most of the day trying to get this damn fan blower working
i took out the fan blower motor cleaned it up oiled it tested it direct to battery it was good took multi meter to switch it was good couldn't figure this dang thing out. after reading your posts here went out there wiggled the resistor and BHAM works like a champ.
I had messed with that resistor earlier in the week because i was trying to diagnose a starting problem. wife is very happy thanks.

Does this apply to a 2001? My blower stopped working too. I checked all the fuses and relays and they tested out ok. I even took the blower out and applied 12 volts to it and it worked. I also tested the wire (that supplies the juice) to the blower and it was putting out power. Thanks

I have a 2002 Dakota with a dead blower motor. I know what the resistor panel looks like but I can't find it on the firewall under the hood. Anybody know where it is on the later models?

check under the hood, on firewall behind the glove box. Plenty of wires going to a plate held in firewall with 2 screws...

Checked the fire wall too no wires there on the 97. Will look
inside firewall behind the glove box, as that is where the
blower is located. - Thanks

I also have a 97 and could not find the Resistor Block, until I asked the Dealer. You have to take the grille off that covers the wiper motor. It is located on the firewall, but you can't see it very well. It is located behind the glove box through the access hole under the grille. Real booger to get out as there is not alot of working room. Would work best with a 1/4" drive ratchet and a 1/4" u-joint. I think the screw are 9/32" or something like that.

I have been to many web sites and have found that it is common for the ristors to go out around 36K miles. Sounds like a recall item (yea right). Any hows ofcourse I have the same problem on my 2001 Dakota truck so not everyone is alone.
