Received both parts and installed on 11/30/1999. $500 was applied under "warranty. " owner still had to pay total of $900+ for parts and labor for a system (abs control module and abs hcu unit) that should not have failed in a car this new! also, if the part ordered the first time was also defective, it would seem that there could be a major problem with these parts at manufacturer's level.
