  Q: How to replace the passenger side wiper arm on Buick Terraza?

  A:

  You need to open the car hood and support it to replace the Wiper Arm on the passenger side. Remove the wiper hose from the washer pump jumper tube. After unwiring the access cap and wiper nut use the Wiper Arm puller (J 39637) to detach the Wiper Arm from the pivot shaft. To disconnect the arm use the Wiper Arm puller (J 39637) on the pivot shaft and take off the Wiper Blade from the arm. Before installing press the Wiper Blade onto the arm and put the Wiper Arm onto the pivot shaft as long as both edges should be level at 4.84 inches (123 mm) distance apart. Use a torque wrench to fasten the Wiper Arm nut on the pivot shaft at 48 n.m but keep the Wiper Arm in place. Afterward attach the finished nut holder and connect the washer tube back to the end of the arm with the hose placed counterclockwise. Check the wiper system operation after closing the hood.

  Q: How to replace the driver side wiper arm on Buick Terraza?

  A:

  You should start by raising and propping open the hood. Unplug the washer hose from the front washer pump hose and take off the Wiper Arm nut cover , then take out the Wiper Arm nut . Take the j 39637 Wiper Arm puller and use it to take the Wiper Arm off the wiper drive system module, then take off the Wiper Blade from its connection to the Wiper Arm. Pull the Wiper Blade onto the Wiper Arm and fit the Wiper Arm into place on the wiper shaft, so the blade tip is over the windshield's horizontal line. Using a device that is perpendicular to the blade tip, ensure that the passenger side Wiper Arm is 123 mm (4.84 in) under the glass solid blackout and the driver side Wiper Arm is 153 mm (6.02 in) above the blackout. Make sure the Wiper Arm does not move and install the Wiper Arm nut, then tighten it to 48 n.m (35 lb ft). Now, put the Wiper Arm nut cover on and link the washer nozzle hose back to the washer pump hose. Be sure to close the hood, then look over the wipers to make sure they function correctly.
