Problem overview

Some Chevrolet Express 2500 owners report experiencing water leaking from the dashboard during left turns, which may be attributed to incorrect windshield installation. This issue can lead to water seeping into the vehicle's interior, causing inconvenience and potential damage. Additionally, some owners have noted that water may leak behind the driver's side dash during rain due to voids in body seam areas, resulting in wet carpets and musty odors. Problems with the engine cowling area, which houses the air intake network, might also allow water to enter the cabin, particularly in rainy conditions. Furthermore, a cracked wiper fluid reservoir can contribute to leaks near the front tires, with water exhibiting a slight blue or green tint. Lastly, using water in the windshield wiper fluid can cause freezing and expansion, potentially leading to cracks in the plastic container and subsequent leaks. Promptly addressing the windshield installation issue is crucial to prevent further water ingress into the dashboard area.
