Re: A/C Question
1)stop using the recirc function once the vehicle is cooled down-use the fresh air intake to maintain cool
2)bulletin just appeared in GMland so don't fault dealer for not seeing earlier-it's dated June 12th. bulletin number is 99-01-39-004C. It's an old trick that Cadillac has done for many years and works well. Basically it's adding a module to run the HVAC fan for a few minutes once vehicle is shut off. Don't be alarmed when you walk past front of your truck with keys in hand and hear fan running from cowl area.
edit-there's no HVAC(cabin) filter in your truck.
