Jeep Grand Cherokee AC compressor failure and transmission not shifting into gear or overdrive on Jeep Grand Cherokee

Some Jeep Grand Cherokee owners report experiencing issues with the AC compressor, such as failure requiring replacement rather than repair, which can lead to improper cooling or the compressor not functioning at all. Wiring problems, including blown fuses, may also result in the air blowing at outside temperatures. The cost for compressor replacement typically ranges from $200 to $500. Additionally, some owners encounter transmission problems, including difficulty shifting into gear or overdrive, often linked to a leaking transmission cooler, which can cost around $850 to replace and may not be covered under warranty. Other factors, such as coolant over or underfill, or issues with the AC compressor and related components, can contribute to transmission malfunctions and unusual sounds. It is crucial for owners to seek professional assistance to properly diagnose and address these separate issues to maintain the functionality of both the AC system and the transmission in their Jeep Grand Cherokee.
