Question about 2002 Buick Rendezvous
The most common cause for this problem that I see is a failed rear "Differential oil flow valve". You would need someone to hook up to the vehicle with a scan tool and retrieve the service code to know for sure but the valve is usually the culprit in most cases. There may be a code that says something like "rear axle over temp condition" and this relates to the valve problem. There are other things that can cause the AWD light to come on so it's always good to check first before replacing parts as the valve is fairly expensive. Good luck, hope this helps!
