SUBJECT: WINDSHIELD WIPER BLADE CHATTER/WIPEABILITY CONCERNS CAUSED BY CHANGE IN BLADE ANGLE (INSTALL SPACER)


MODELS AFFECTED: 1982-1988 CIMARRONS


Some 1982-1988 Cimarrons may experience a condition of driver side blade chatter and wipeability concerns. This condition may be caused by wiper housing mounting tolerances that change the attack angle of the driver side blade assembly.


IMPORTANTBefore doing any work, clean windshieid and both blades with GM windshield cleaner, P/N 1050011, or equivalent. Then recheck wiper-washer operation. If problems persist after cleaning, follow the procedures in this bulletin.

Figure 1 - Installation of Spacer:

To repair this condition install spacer, P/N 22111290, over driver side linkage housing. Refer to Figure 1. Make sure spacer is correctly oriented. Parts are currently available at GMSPO.


Finger tighten the new screws provided, then tighten evenly to 8 Nm (70 lbs.in.).


NOTE: When reassembling cowl, make sure that washer hose is reconnected (and not pinched).


If an interference condition results between the wiper arm head casting and the cowl clearance hole, use a file to enlarge hole at interference point.
