Wiper System & Washer System: Other Dodge Durango I

WIPER BLADES

With wiper arms removed, cycle wiper motor into PARK position. Mount arms on pivot shafts, and ensure wipers are within 0.59" (15.0 mm) of wiper alignment marks. (Scheme 4) On rear wiper, align blade with line in lower blackout area. Operate wiper blades, and check whether they return to proper position. If wiper blades do not return to this position, check linkage and pivot assembly for wear and binding.
