Some Chevrolet Equinox owners report experiencing HVAC system failures after a battery failure, often accompanied by a lack of dashboard lights. Many have found that resetting the battery or performing a software update can resolve these issues. Additionally, some owners have identified climate control electrical problems that necessitate troubleshooting and resetting the climate control system. If the AC is not functioning, it may indicate a compressor issue that requires inspection and repair. Others have reported inconsistent air temperatures due to a malfunctioning blend air door within the HVAC system.
