HUMMER History.

1994 Hummer Model Year Changes.

There were many changes for Hummer in 1994. The drivetrain changes were probably the most significant. While the '92 and '93 models had a 6.2L engine and 3 speed transmission, the '94 version came standard with a 6.5L engine with an additional 20 hp and 40 lb ft of torque and a 4 speed transmission. The 4 speed transmission allowed the Hummer to cruise at much lower RPM reducing the noise level at highway speed considerably. Top speed went from about 73 mph to 83 mph. Also new for '94 was the availability of luxury features such as power windows, power door locks, power mirrors and cruise control. Approximately 718 H1s were produced for the '94 model year.

Valuable upgrades and mechanical issues to look for in a '94.
  • '97.5 Style HVAC system. About a $4,500 to $5,000 upgrade. Much improved Heating and cooling and new unit is more easily repaired than earlier sealed units. Make sure heater core is not leaking on non-upgraded HVACs. Expensive upgrade to '97.5 specs is factory recommended solution to this problem.
  • Later ball joints and the factory "Problem Solver" Idler and Pitman arms are much more durable than those on a '94.
  • Some owners have added the '97 style scupper valves and air intake scoops to aid in ventilation and to improve air flow and defrosting. Windshield frosting is a common problem before heated windshields and enhanced ventilation became available in '97. You may also find some earlier Hummers that have had the heated windshields added which is a costly upgrade.
  • Updated heat shields. Limits common cracking and rattling. If a '94 is not rattling it has probably been updated.
  • Half shaft bolts had a tendency to back out occasionally to the point they would interfere with and damage the brake rotor. The addition of "Nord Lock" washers keeps the bolts from backing out.
  • Small rubber plug in Transfercase sometimes shrank due to heat and fell out, slowly draining Transfercase. Later designs solved this problem. Some owners tapped the hole and replaced the rubber plug with a metal one.
  • Shifter boot would become hot and tear allowing hot air from under the vehicle to enter the cabin. The '97 style shifter boot cover helps this problem.
