2008 GL550, A/C no air comes out while blow motor run normally
Hi, members!
The A/C system works well from the first start of the vehicle until it has been driven for about 30~60 minutes. But after that, the blowing air gets weaker and the air doesn't come out of the A/C. Even when there is no wind, I can hear the blow motor sound operating normally. In manual mode, if I increase the blowing level, the blow motor runs more vigorously, but no wind comes out. It does not come out in any directions, defrost direction, front direction, and footwell direction. In manual mode, nothing happen if I change the wind direction button on A/C head unit. If I push the 'defrost' button, blowing motor runs maximum power but no air comes out. The symptoms are same whether I turn on the heater in winter season or cooler in summer season.
Anyone have had same or similer experience before?
