2003 Hummer H1 Model Year Changes and Buying Guide.

2003 HUMMER H1 Model Year changes.

The 2003 Model year featured mostly refinements from the previous year. Interior enhancements included a Double DIN Audio Controller and Optional Heated Leather Seats which were previously only available in the '02 Anniversary Edition. The HVAC Heater Core was upgraded to use flexible hoses which helped with reliability issues. There were also ducting changes in the '03 HVAC system. Optional Eaton ELocker Rear Differentials available for the first time offer enhanced off-road mobility versus the TorqTrac 4 traction control system alone. The Heavy Duty Brush Guard marks the most visible exterior change. The first 12 Scheduled Maintenance Activities in the 3/36 Warranty Period are free. 494 '03 models built including 112 built specifically for the U.S. Border Patrol.
