My original blower motor on my '03 G35 died, so I took my car to the shop, and they replaced it. The a/c is now working again, but it is not blowing as strong as it used to. I took it back in, and they replaced the cabin filter in an effort to improve the air pressure, which helped slightly, but it's still much weaker than before. The replacement motor part # is listed as "27225-AM611" on the invoice. Any ideas? Is there a better/different blower motor out there that would restore the original air strength?
