Blower fan blows backwards (Chrysler 300)
 

I have a 2004 model 300M with Automatic Temp Control (ATC) system.

About 2 weeks ago my blower stopped working - it was on full blast all time regardless of how I set the dial or even when I turned it off.

I did some research and found that the blower power module needed to be replaced. The part number I had, 04734913AE, had apparently been discontinued and replaced with part 5179985AA.

I got the new part and installed it, however, now the fan blows backwards in relation to the dial - if I turn the dial all the way UP, the fan STOPS. If I turn the dial all the way DOWN, the fan blows full speed.

Given there is only one part I can use, what can I do? Is it just a matter of swapping 2 wires from either the 3-wire or 2-wire harness? I'm assuming I need to make an adjustment since I am using a slightly different part.

Thanks!!!

return the one u got and get one from rockauto.com

Are you saying the part is defective? The dealer price is a lot cheaper than on that website so if it is defective I would just exchange it. But I dont think it is defective.

5179985AA is for jeeps not cars
04734913AE this is what u need and its 250 bucks or more

Thanks
 

Thanks, I returned the part and ordered it from RockAuto.com for half the price the dealer asked.

By the way I got excellent service from the CarMax in Norcross GA if that's where you work.

I did work there for 5 years when I started out in this business
Let me know if there is stuff I can do for you I have my own business fixing Chrysler Dodge and Jeep cars.
