GMC Yukon air conditioning blowing hot air despite multiple Freon refills and no leaks detected on GMC Yukon

Some GMC Yukon owners report experiencing issues with their air conditioning blowing hot air despite multiple Freon refills and no detected leaks. These problems may stem from compressor failure, which is crucial for the AC system's operation. Additionally, a malfunctioning blend door can result in warm air blowing even at the lowest temperature setting, necessitating diagnosis and repair by a mechanic. Faulty air conditioning sensors located under the dash can also lead to inconsistent cooling, and replacing these sensors through a certified dealer may be required. Furthermore, a broken rod in the flap that directs cold air to the rear system can cause hot air to escape from the front vents, indicating the need for part replacement. It is important for owners to address these issues promptly to restore proper cooling functionality in their GMC Yukons.
