I have a 2002 Buick Rendezvous, 44,000 miles. My a/c is malfunctioning, it works every thrid or fourth time I start the car. Three people have told me that this is something that is covered under warranty but I can't find anything to that effect in the warranty info. Before I spend the $$ to get it fixed, I want to make sure it is not covered under the warranty. Someone smarter than me must know this answer. Thanks.
