• Blow motor.

    From Mark Hofmann@1:261/1304 to All on Fri Aug 30 13:59:48 2013
    In my experience, all cars have their "hereditary issues" over time. Some more
    severe than others. If you keep a car long enough, you will see them happen. Just like with people. :)


    One of those such issues with the Durangos is the blower motor relay and/or blower motor. If you do a google search for durango and blower motor relay, you will find loads of people with this issue.

    Basically, Dodge has a defective wiring harness that is the crux of the problem. It causes the connectors to melt and burn up. I'm actually suprised this wasn't a recall.

    Anyway, this is my "third" attempt to correct this problem once and for all. I
    have already re-wired the effected connector, replaced the blower relay (3) times, and (1) blower motor.

    This time around the issue is 100% the blower motor, itself. Making a really loud noise when running and smells like it is burning up. No doubt the last time I replaced this motor, the replacement part was made in China.

    I managed to find a new genuine Dodge blower motor for the Durango on Amazon and am going to install it this weekend. Fortunately, it isn't a difficult repair, just awkward since you have to work upside down on your back.

    Then I hope we are done with Durango issues for awhile.

    Just where do they mount that blower motor relay. I find that the blower
    motor relay in my Silverado is a little discolored but no melting to speak
    of. The control switch is on the dash, but the actual relay and motor
    speed resistor pak is under the dash next to the blower motor. It's in a
    little vented box (next to the cabin filter housing) which I think helps
    to keep it cool. Mine is 11 years old and no issues yet.

    Check the amperage load on that motor in each speed range. Too much of a
    load will create a lot of heat that the relay and resister pak has to
    handle.

    Speaking of Blower motors.

    Last spring I replaced the cabin filters that most pickup trucks and most Tahoes and Suburbans come with.

    The Silverado requires two such filters installed back to back, which are
    easy to R&R, once you learn how. The first time I did this, there were
    two filters in the box, but I couldn't find more than one in the slot
    where they go under the dash. This time I was bound and determined to
    change both, as I was hearing some noises in the high-speed ranges of the blower motor.

    I finally found it, but it wasn't in plain sight, which is why I missed it
    last year. Long story short, I changed them both, but that didn't ease
    the blower motor noise. So, I went back to my Silverado manual and found
    that I could R&R the blower motor with the removal of one screw and a
    twist of the motor housing.

    As it turned out, the blower motor was full of leaves that the first
    filter had stopped, but they were also the cause of the motor noise and
    what seemed to be an 'imbalance' of the squirel-cage fan. I can now use
    the blower at full speed and it is like new again.

    It is mounted in a similar location on the Durango. Not far from the blower motor, up inside the vent area. Just a few bolts hold it up there. On the passenger side about a foot away from the blower motor. Remove two bolts and it comes down.

    My first connector was melted so bad, I couldn't remove it. I had to cut the wires and re-do everything with wire-nuts.

    The problem with the Durango is the wire harness melts/shorts and fries the blower motor relay. When that happens, just the high setting doesn't work. Everything else does work. Happened to me three times, until I replaced the wire harness and blower motor itself.

    There is a case where the blower motor can draw too much power and fry them over and over again.

    Check the amperage load on that motor in each speed range. Too much of a load will create a lot of heat that the relay and resister pak has to handle.

    Yes, that is what causes many of the failures. The best bet when someone with a Durango has a problem like this, is replace everything. Wire harness, blower
    motor resister, and blower motor.

    Yes, fortunately many blower motors are not too difficult to remove. Getting leaves in there would certainly be an annoying noise. :)

    Oddly, the Durango doesn't have a filter. I'm not sure if the Monte Carlo does
    or not, but if it does, I have never replaced it. Will have to look into that.

    It sounded like the old playing card in the spokes trick we did when I was
    a kid.

    I forget what year your Monte is, but I did find a listing for 2001
    Monte', they cost about $10...a search for Durangos finds a lot of people asking about cabin filters, but nothing specific shows up.

    :) I did that, too.

    I can imagine it would sound just like that. The blower motors have that same type of style that would make that noise if something was stuck in there.

    It is a 2002 Monte Carlo LS. I will have to search to find where they are located in the Monte. I never replaced mine.

    I remember reading somewhere that the Durangos don't have a cabin air filter. Lots of people ask, but I seem to remember someone saying they don't have one.

    They'll be close to the blower motor.

    I saw that on several Durango blogs...not sure if anyone ever figured out
    if they have them.

    From everything I have read/seen, they don't have them.

    I did locate where the Monte Carlo cabin air filter is located. You have to raise the hood, wipers, and remove a few screws on the cover between the engine
    firewall and windsield. Basically, it is under that plastic cover.

    I would imagine mine is really dirty. Will have to check it.

    Sounds like where the heater in my 95 Z28 was located. Truely a 90 minute
    R&R of the heater radiator.

    Take a shop vac with you to clean out the airbox...

    Yes, years ago I replaced a heater core in my old 1985 Camaro. It took me most
    of the afternoon to get to it. Had pull most of the dash on the passenger side
    apart and then reach down behind the dash to get it out. Not a fun job.

    Good idea.

    Sounds like they designed the 4th gen Camaro heater core replacement with
    ease in mind.

    Yes, probably after many mechanics complained.. :)

    Sort of like how GM added an access panel to many later model vehicles to access the fuel pump without dropping the tank.

    I am thankful that my Monte Carlo has that access panel for when I go to tackle
    that job eventually.

    Probably so, as the 3rd gen heater core was nearly impossible to R&R..

    Sort of like how GM added an access panel to many later model
    vehicles to access the fuel pump without dropping the tank.

    Wish they had done that in the 3rd gen Camaro as well. I had to replace
    one of those once and it was no picnic while dropping the rear end far
    enough to R&R the fuel tank.

    I am thankful that my Monte Carlo has that access panel for when I go
    to tackle that job eventually.

    Well there is an alternative. You can buy an external fuel pump that will provide the same 45lb PSI as the internal pump and get by for a much
    lower price. I did that with my 3rd gen Camaro and sold it soon
    thereafter.
