Dorman - HELP Windshield Wiper Arm P/N:42021
Dorman 42784 front left windshield wiper arm for the 2012-2020 Dodge Grand Caravan and other vehicles carries the wiper blade across the glass and holds it against the windshield.
A blade that lifts off the glass, skips or leaves unwiped strips can mean the arm spring has weakened or the arm is bent. These signs alone do not prove the arm is the problem; a worn wiper blade is another common cause of streaking.
This arm fits the 2012-2020 Dodge Grand Caravan, the 2012-2016 Chrysler Town & Country and the 2012-2015 Ram C/V. Each takes one arm on the front left; the front right arm is a separate part, ordered separately.
