Malfunctioning climate control in the S-Class often occurs because of:

Sensor Failures: Temperature sensors inside the cabin o r engine bay may malfunction, causing incorrect readings and improper climate control responses.

Refrigerant Leaks: Over time, the air conditioning system may develop leaks, reducing cooling efficiency.

Faulty Control Modules: Electronic control units managing climate functions can fail o r suffer software glitches.

Extreme Weather: High temperatures and dust in Pakistan can stress the system, leading to quicker wear and faults.

Lack of Maintenance: Neglecting regular servicing, such as refrigerant top-ups and filter changes, worsens problems.

Timely servicing and repairs at authorized service centers help maintain the climate control system’s performance.
