My windshield wipers stopped working.

There is 2 bolts on each hood hing loosen them and move the hood. As far as the wipers it sounds like the wiper linkage got bent.

Possible wiper linkage has broken/seperated from wiper motor. The wiper cowling covering the linkage assembly will need to be removed to inspect/repair

Sorry , no adjustment .
Wiper/Washer System Components
The Wiper / Washer System consists of the following components:
• Windshield wiper / washer switch
• Windshield wiper system module / motor
• Windshield washer fluid pump
• Windshield washer fluid level switch
• WPR 25A fuse
Wiper / Washer System Operation
The windshield wiper motor module is part of the windshield wiper motor cover and controls the wiper motor operation. The windshield wiper motor is a 2 speed motor. Windshield wiper DELAY operation is a low speed wiper motor function with a variable delay interval between the wipe cycles. The DELAY interval is controlled through a series of resistors within the wiper / washer switch.
Park Position Operation
When the windshield wiper / washer switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the wiper motor module will continue to operate the wiper motor until the wipers reach the park position. If the ignition is turned off while the wipers are in mid-cycle, the wipers will stop immediately where they are. The wipers will park the next time the ignition is cycled to the ON position.

Could be loose wiper arm. Are the blades heavy. Too big of wiper blade will cause problems

Hi, They are connected look at fuse's this may be the problem. Please leave me feedback, Malcolm Campbell.

At the base of the wiper arm there is a plastic cap,pop this off ,underneath there is a nut that holds the arm in place ,if it gets loose the post will turn inside the blade.Just turn the wipers off and tighten the nuts with the blade in the parked position.

Sounds like it's your switch or a bad relay

Could be anything but based on experience the probability points to the self cancelling switching in the motor gearbox.

did you ever get an answer I have the same problem. NOw my turn signals don't work and my wipers do??
