Why is there no air coming out from the front of the Cadillac ATSL's air conditioner?

[MacMackenzie]

There are several reasons why the front air vents of the Cadillac ATSL's air conditioner may not be blowing air: 1. Blower motor issue: The blower motor is the core component responsible for air circulation in the car's air conditioning system. If it is damaged, the air conditioner will not blow air. Blower motor failure could be due to overheating and damage of internal coils or capacitor failure. You can check for this issue by turning the air conditioner's fan speed and air volume to the maximum and listening for any abnormal sounds from the blower motor. 2. Blocked air ducts: Outside air passes through the cabin air filter before entering the car, which can accumulate a lot of debris from the air, leading to blockages.
