# POOR HEATER PERFORMANCE IN REAR SEAT AREA

POOR HEATER PERFORMANCE

#### Vehicles Affected: 1987-88 "L" CARS -----------------

Some customers may comment on poor heater performance in the area of the rear seats, mainly the left rear.

If the heater system is operating properly with adequate heat in the front seat area, the problem maybe caused by poor heat/air distribution from the floor heater outlet.

This condition can be improved by replacing the existing floor heater outlet with one of the following new parts.

RPO Part Name Part Number --- --------- ----------- C41 Heater Outlet Assy. 10065639 C60 Heater Outlet Assy. 10065788

The breakpoint for vehicles with the new outlet assembly at both assembly plants, is VIN 500,000.

Use applicable labour operation time.
