GMC Acadia water leakage from glove box after AC service, suspected windshield seal issue on GMC Acadia

Some GMC Acadia owners report experiencing water leakage from the glove box area, which may not be related to the windshield seal. These leaks are often attributed to a blocked AC hose, a common issue that can lead to water accumulation. Additionally, some owners notice that the AC system may leak water directly underneath the engine bay, causing water to drip onto the passenger side floor mat. In certain cases, finding water in the blower cap under the glove box suggests a sunroof leak rather than a windshield issue. Furthermore, water entering through the rear sunroof and running down a channel has been identified as a potential cause of leaks. Lastly, some owners find water puddling on the passenger side, which can drip into the passenger fuse box, potentially indicating water intrusion from the AC system or sunroof drains. It is recommended to thoroughly inspect these areas before concluding that the windshield seal is to blame for the water leakage.
