I noticed a smell of mold from the ac vents, I took the car to city Chevrolet in charlotte, nc. They replaced the ac condenser unit. This took care of the smell for the summer months. The smell has now returned and is getting worse by the day. The service agent said that gm was aware for the problem but was doing nothing to correct. I was also told this is a design flaw due to the vents in the condenser being too small not allowing the built up water to evaporate. This issue is starting to cause health problems such as bronchitis and sinus infections.
