OK, after a year of banging on it with a screwdriver and procrastinating, my blower control module has finally given up the ghost. My BCM is bad and fastblackmerc is fresh out of repaired BCMs (don't forget to send your old one back folks!), so I’m been trying different options. I toyed with the idea of saving myself time but losing money and emailed the stealership for price on a 9W73-19E624-AA. They email me back that they have a compatible 8W7Z-19E624-A at a cost of $131.36 before tax and labor. That part appears to match AutoZone part JA1710 for ~$43.99: http://www.autozone.com/autozone/par...ier=79885_0_0_
Is there any reason this AutoZone replacement BCM would be incompatible or a bad idea?
