LACK OF HEAT TO DRIVER'S FEET REMOVE PORTION OF FLOOR OUTLET

MODELS: 1989-1990 M/L VANS

Some drivers of later 1989 and early 1990 M/L vans may report "cold feet" or a lack of heat to the driver's floor area. This can be caused by an insuf- ficient airflow distribution from the floor outlet assembly to the driver's feet.

A revised floor air outlet assembly has been released for production. Vehicle Identification Number breakpoints are:

GMC 1GKDM15Z0LB517220

Chevrolet 1GNDM15Z9LB152071

To correct this condition at the dealership, it is necessary to cut out a small portion of the existing floor air outlet assembly.

INSTRUCTIONS: (Refer to Figure 1)

1. Remove engine cover.

2. Detach the floor air outlet assembly (P/N 15601727), located near the gas pedal and engine cover, from the air distributor assembly by removing two screws (P/N 11508917) and two washers (P/N 2077521). Slide the floor air outlet assembly to the right being caretul not to break off the guide retainers molded into the top of the air outlet assembly.

3. Use a hacksaw or other appropriate cutting tool to remove a small four-sided section of the floor air outlet assembly as shown in Figure 1.

Cut along the top and the left side of the cut-out area only. A smaller almost triangular area located between the existing open area and the cut-out area should remain intact.

4. Reinstall the floor air outlet assembly onto the air distributor assembly using the two previously removed screws and washers. Torque the screws to 1.2 to 1.6 N-m (11 to 14 in. lbs.).
