TSB's

Hi
I'm new to this forum, came across it searching for repair info.  I have an '03 Malibu with a common problem.  The blower only works on 4 & 5.  I have found that it is probably the resistor.  I also see that it is the subject of a TSB.
Does that mean that a dealer will replace it at no charge to the owner, or does it just mean that GM knows it's a crappy part and that dealers can expect to make a lot of money replacing them?
 
Thanks in advance, and I have found the forum helpful.
 
 

A TSB is a technical service bulletin and tells you how to fix it. A RECALL notice is when the dealer will replace it at no charge to the owner. Did you get a letter in the mail about the recall?
