36,169, and my A/C just went. I have an appointment in the morning with the service department. I just had my car service four days ago. Let see what the service GM Service does to resolve this issue.
I suspect you are 169 miles out of warranty for the AC, but your dealership might still fix it for free to keep you as a costumer. Please let us know how it is resolved.
Condensers are a major complaint on the 15-20 Tahoe.
Good luck; here’s hoping it’s something simple and doesn’t cost too much.
