Air Conditioning problem
2005 Other Pontiac Models

I noticed that when I tried to have some cool ventilation come into the truck that only warm air came in. I then tried to turn the A/C on and noticed no cool air coming in. I also noticed the temperature gauge in the car showed substantial heating, even though the heating is not on. I think something is wrong with the A/C, however I would like some information prior to bringing it in. Just want to be armed with information. Thanks.
