Re: [Chrysler300] 300 factory air blower motor

Hi Allan,

Re your blower motor question, I replaced the one in my F last year with the Paccar motor. Using our website  comment, I went into my nearby Peterbilt shop and they advised that Paccar HA1105 is the current motor, replacing the previous HA1100. I bought it over the counter. I installed it and it bolts right up and works just fine, although it's somewhat noisier than my factory original motor. The cost was in the US $65-$70 range. I'm guessing in the big trucks, you'd never hear this heater motor noise. 

The truck shop is close to both of us - JX Truck Center, 535 E S. Frontage Road, Bolingbrook, IL - right along I-55.

This past winter, I had my local buddy rebuild my factory original motor, and am now deciding whether to go thru the substantial effort of swapping out the Paccar motor for my new original one.

Greeting all factory air 300 owners! May I ask if anyone has gone down the blower motor replacement avenue? I dismantled my interior yesterday getting the 950 heater plenum out of my 300 K to service the squealing blower motor. Seats,console out.

I find that the air conditioned cars show a different blower motor that the regular heater cars. Motor # 1879 579 shows up for Chrysler and also Dodge/Plymouth AC cars in 1964. This number is also good back to 1961 for AC cars. I checked the MOPAR cross reference chart and find nothing regarding the AC motors.

I have searched for this number online and find nothing. I did find a reference come up on a Hemmings page referring to a report from November 2011 giving a cross reference and substitution list for all MOPAR blower motors. The data is no longer showing on the web page. 

Can I ask if anyone has a Hemmings subscription and would kindly search this article out? The Hemmings web page is: 
Click on the link and you will go here:

I'd like to get a new replacement sooner rather than much later as with my getting my old motor rebuilt. Not sure anyone would replace the bushings, and I don't know the condition of the armature shaft. I don't want to do this again!

If that is my only option, well all righty then!
