Wiper System & Washer System: Other Dodge Caravan III

WIPER BLADES

1. Ensure wiper blades and wiper arm spring tension are okay. While applying water to windshield, observe wiper low speed operation. If wiper element is not rolling over when wiper direction reverses, extension bar portion of wiper arm needs to be twisted in proper direction.
2. To twist extension bar portion of wiper arm, use 2 small adjustable wrenches positioned 2" (50 mm) apart on wiper arm extension rod. Twist extension rod slightly in opposite direction while holding wrench closest to pivot stationary.
3. Cycle wipers to park position. Ensure distances between wiper blades and above cowling are as specified in illustration. (Scheme 4)
