I'm looking to buy a working climate control unit as mine only has a few buttons that light up and the power button does not work and the LED display is out. The last two letters on my part number are an AA. Does anybody know the difference between all the different possibilities such as, AA, AB, AD, AE etc.........? Thank you for your knowledge.

 

Oh yes, I forgot to mentions why I am asking this. The prices are all over the place with these units but the 2 that I found with my AA are over $230 dollars. Thanks again for any input.

 

those are version/batch codes. they may be identical, with different manufacturing dates, or they may have very subtle differences/improvements.

The AA after the ### are for the reversion it is. AA the the first part run. I think all with the same part ## will work. I have been retired form Chryslar for 5 years now.
