1999 Chevrolet Tahoe Q&A
1999 Chevrolet Tahoe Question: why does my wiper over extend past the door?
Follow these steps exactly! Turn key on, next turn wiper on,,,,now turn wiper off and let it stop,, turn key off and put wiper in the normal parked position,, now tighten the 'loose' retainer nut, under the plastic cover, at the base of the wiper arm. Test wiper operation. Adjust if needed. - pushrod
Check the splines on the wiper arm. If that is ok the link bush on the motor to wiper spindle is worn or loose. Do both wiper arms move in unison - casarova
REPOSITION WIPER ARM OR WIPER SPINDLE - globalhelper
