2010 GMC Acadia Engine cooling Problems

“My husband and I purchased a 2010 Gmc Acadia in july 2012. Since we've had the vehicle we have already had to replace the water pump which fortunately it was covered under warranty. But now the AC in the vehicle has stopped working. The technician did a black light testing of the AC and it revealed large areas of ultra-violet dye covering the AC hoses and surrounding area.

“Since I got the car set 2012 have stink coming from air vent A/C sometimes pretty bad now in spring when the A/C is on have a weird noise and is not cool at all and I can fell the moist besides I can see a smoke coming from the A/C vent.

Dealer stated noting is wrong because the check engine light is not on. On start up after overnight parked-there is a visible puff of black smoke. Vehicle had 2800 miles, the dealer told me that it needed to be driven, so I drove 2000 miles in a week, it made no sense to me and it did not make a difference.
