Followed a thread regarding distributor cap and rotor corrosion caused by clogged distributor vent screens on my 2003 GMC Sonoma (S-10 with GMC stickers!) I'm battling with GM right now over whether or not this is a manufacturing problem. This website points to a TSB (03-06-04-041A - (Jan 28, 2005) regarding this exact problem, however GM Customer assistance can't seem to find this bulletin number in their system. Is there a different number they may recognize? This son-of-a-gun let me sit along I-95, 325 miles from home, New Year's Eve with my 78 year old Mother in law! GM owes me something! Any help will be greatly appreciated!
