CORRECTION:
The first step in eliminating wiper noise is to ensure that the glass and the blades are clean and free of contaminants. Common contaminants that are
not removed by conventional glass cleaners can be removed with Bon Ami(r), a household cleanser.
The cleanser should be applied on a wet cloth or sponge and the windshield must be thoroughly and evenly scrubbed. Wipe off the residue with a
clean, dry cloth before the cleanser dries on the glass.
If there is evidence of heavy overspray of waxes or silicones on the glass, a wax and silicone remover can be used to remove them.
Clean the wiper blades with a clean cloth soaked in rubbing alcohol.
Once the blades and glass have been cleaned, check the adjustment of the wiper arms and blades per Repair Manual, section 61 61 100, and adjust as
necessary. The adjustment gauges and tools for all models have previously been distributed. Refer to Special Tool CD SD-92-1 29 for ordering
additional tools, as well as the various Repair Manuals for instructions on using them.
