I have an '03 Honda Civic EX manual 5spd, and the A/C works great when I start the car, but if I stop at a red light or let the car idle, the A/C goes warm and I get this weird smell. Almost like stale air. The A/C doesn't get cold when I start driving again, I have to turn the car off and let it sit for 5-10 minutes. The A/C also goes warm after 10 or so minutes of normal driving with no idling. Any ideas of what the problem could be? I did get a recharge about 2 weeks ago.
