Hummer H2 electrical issues including wet driver floor, non-functional phone charger and lighter, inoperative steering wheel controls, and heated seat malfunction after rain on Hummer H2

Some Hummer H2 owners report experiencing electrical issues, such as a wet driver floor, non-functional phone charger and lighter, inoperative steering wheel controls, and heated seat malfunctions after rain. These problems may arise from water leaks due to faulty seals around the windshield, doors, or sunroof, leading to wet floors on both sides of the vehicle. Additionally, owners have noted that electrical issues like non-functional power outlets could result from water damage or blown fuses, necessitating a check of the fuse box and connections. Inoperative steering wheel controls are often linked to wiring problems or malfunctions in the control module, requiring inspection of the wiring harness. Furthermore, heated seat malfunctions after rain may indicate water intrusion into the seat's electrical components, which can be addressed by drying out affected areas and checking for damage. It is recommended that owners consult a qualified mechanic or auto electrician to diagnose and resolve these electrical issues promptly for optimal vehicle performance.
