Hello! my rear amp on my 8 (2005 auto) recently blew and I'm looking for a replacement part, I had called Mazda for some info (I'm not too savy on this topic), I gave her my VIN then she had responded to me with a bunch of numbers as well as she told me that if the car it came from had heated seats it wouldn't match with my car, the numbers she gave me were " FE17-156372 said for those numbers in the other cars VIN would be a match for my rear amp, other numbers (not to sure what she means with this) "125165-200001 top to bottom" any elaboration and thoughts as well as where I may be able to buy a replacement rear amp would be much appreciated! I can also provide my VIN if needed! thanks everyone!
