Dodge Caravan A/C Heater Blower Goes In and Out!!

2005 Dodge Caravan A/C Heater Blower Goes In and Out!!

I have a 2005 Dodge Caravan V6 Sport.  The air conditioner started going out while we when on a summer road trip.  It started going out slowly, the blower motor not turning as fast as it usually did.  It also started making a growling noise.  Then it continued to work less over the next few days.  It got to the point where it was a 50/50 chance if we were going to have A/C or not!

It either worked fine or it was totally out!  No fan air or anything when it quit working!  So this made me believe that there was nothing wrong with the air conditioning system because it did work sometimes and the fan didn't work when the system quit.  This lead me to believe that it hade something to do with the blower motor, blower resistor, a relay, or the control module.  We then noticed that if we tapped until the glove compartment with our feet, that the blower came on.  So that eliminated the control module and relay.

I started by replacing the blower resistor.  It can literally be replaced in 5 minutes and it's just a $20 part from the parts store!  That's where I'd start if I was doing this repair!  You open the glove compartment, you squeeze the glove compartment together so the back 2 rollers come out from behind the dash, then the rest of the glove compartment door unsnaps at the bottom.  The resistor is right there in plain sight!  It has 2 8mm screws holding it in, and you'll have to remove the 2 wire harness's from it!

That didn't fix it on mine, it ended up being the blower motor!  With the glove compartment door off, there are 4 or 5 8mm screws that hold on the access to the blower motor.  The blower motor is all the way to the right if you looking at the glove box!  Before you can take the access panel off, you have to remove the square motor at the bottom that turns the blower recirculation vent on and off!  It has 2 8mm screws that hold it on.  There's not very much clearance room right here, it's a tight fit!  You'll have to pull the carpet back and use either an 8mm wrench or a type of gooseneck extension in order to get a socket on it!  *Note*  When you put this recirculation motor back on, you'll have to have it on the same setting as the vent is positioned!  For example; if the recirculation button is on and the motor is plugged in and in that position, you'll have to position the recirc vent in that position also or they'll be out of sync!!

There are 3 8mm screws that hold the blower motor in!  Remove those and I wiggled the blower in order to get it out!  I didn't remove the recirc vent, I just left it in and worked around it!  How this article helps!  Feel free to share and leave comments!!  The blower motor can be replaced in 1-2 hours!  Thanks for reading and good luck!!
