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.
But you are probably still in by time. Your warranty is still expired, but
you may be able to get a dealer to do it anyway. They have the option to
approve repairs like that to be covered under warranty. If you take it to
where you bought it and talk to the Service Manager, You may be able to get
it done. If you have ever bought any other cars at that dealer, mention that
too. Most places will take care of regular customers. If you show up with a
car you bought somewhere else, they usually will turn you down. Just tell
them that you don't feel that this should have gone out so soon on a 2002.
If they won't help, try calling GM using the number in the back of the book.
There is a bulletin number 20-01-39-008 for this vehicle it talks about a
leak through the a/c high pressure switch. Yours doesn't really sound like
that but you never know. I don't know if the system is low. If I had to
guess without seeing it, I would say the cycling switch on the accumulator
is bad(a common problem on GM trucks) If you know what switch I am talking
about, the next time you turn it on and it won't come on, leave it on and
open the hood and tap the switch with the handle of a screwdriver and if it
kicks right on that would be the problem.
