Mercedes-Benz GLE350 heating issue with cool air blowing and noise from driver’s bell on Mercedes-Benz GLE350

Some Mercedes-Benz GLE350 owners report experiencing issues with heating, such as cool air blowing when heat is expected. This problem may stem from the fan or blower motor malfunctioning, which could be caused by a blown fuse, bad relay, or issues with the control module. Additionally, low or overcharged refrigerant, compressor malfunctions, and clogged cabin air filters can contribute to inadequate cooling performance. Furthermore, some owners notice noise coming from the driver's side, which may indicate problems with the blower motor or its components, potentially due to debris accumulation or malfunctioning parts. It is advisable for owners to have their vehicles inspected by a qualified mechanic or authorized Mercedes-Benz service center to diagnose and address these heating and cooling issues promptly.
