SLOW FRONT WINDSHIELD WASHER PUMP RESPONSE TIME

VEHICLES AFFECTED: Affected 1984 'F' Models

Customers may comment on some 1984 'F' models about front windshield washer pump response time. A properly operating system will apply a full spray pattern of fluid to the windshield before completion of the first wipe cycle (from park to full wipe, back to park).

This condition is attributable to the washer fluid draining back into the container and the washer pump having to be re-primed.

To correct this condition the washer hoses must be re-routed to provide an anti-drainback loop. This is accomplished by routing the washer hose under the accelerator cable, over and rearward of the brake booster, down to the side rall and forward to the solvent container (see illustration).

The washer hose should be shortened as required to eliminate the excessive length. The right and left hose assembly to the washer nozzles should be replaced with 5/32 inch (4.0mm) inside diameter hose, and routed per illustration. (Start of production hose was 7/32 inch inside diameter.)

The hose routing change was implemented in production in January, 1984. The small diameter hoses were implemented in production in April, 1984.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
