Need Help with your wipers on a Chevy Venture they stop straight up otherwise work well but they will not park What can you do?

Answer 1

The mechanism that causes the arms to park is part of the rotating arm that make the wipers move. If the wipers function in all other ways except for parking, the problem is in the rotating arm. to be sure that this is the case, remove the cover that covers the wiper mechanism while the vehicle is off and the wipers are turned off. Turn the vehicle key on and turn the wipers on to the low setting. The arm should rotate clockwise. When you turn the wipers off, the wipers should stop near the bottom of the windshield then the motor should rotate counterclockwise a little more than half of a turn. This action will park the arms if all is working properly. If your arms go back up the windshield and stop near vertical then the problem is in the arm. To remove the arm, be sure that the power is off. Disconnect the positive terminal on the battery. Remove the arm by loosening the two 8mm bolts on the linkage that connect to the arm. Then remove the t30 bolt from the center of the arm. lift up on the arm and tap on the center bolt before it is fully unthreaded. This arm consists of many moving parts, all of which are necessary for the park function to work. The first thing to check is the small flip lever on the bottom of the rotating arm. It should move freely and be spring loaded to keep the lever pushed to the outside. If it is not free, use some penetrating oil and needle nose pliers to free it. The other thing that must be done is lube the remaining parts and work them by hand to free them of corrosion. The spring that wraps around the middle can be gently removed and all parts can be oiled and worked till they are free. To reinstall the arm, turn on the wiper motor without the arm attached in the delay function. When the delay function pauses the motor turn the key off and attach the arm with the flip lever on the bottom, just clockwise past the stop on the frame. Reattach the linkage and test the unit.
