To troubleshoot car windshield wiper problems, you need to thoroughly investigate problems with any of its operating parts. Here are some of the things that you need to check to determine why are your car windshield wipers not working.
Check Wiper Motor
The wiper motor is the driving force of the windshield wiper. Feel the motor and listen to a humming sound. If there is no humming, the motor is the problem. Check if the motor is working properly and see to it that its electrical connections are made properly. If you find that the motor is dead and beyond repair, get it replaced immediately.
Check For Break in Connecting Wires
The connecting wires of the motor sometimes go loose and that may cause the windshield wipers to stop working. Also check the battery plug connection which the motor has. Connecting the loose wires properly or fixing/replacing the plug might solve your problem.
Check Wiper Switch
Another wiper assembly part that can malfunction is the wiper switch itself. Check for switch malfunction and if you find that is indeed the problem, get it replaced from a mechanic.
Check for Bent Wiper Arms
Bent wiper arms can cause the operation of the wipers to be hampered. If the wiper arms are bent beyond repair, get them replaced immediately.
Check For Blown Out Car Fuse
A blown up car fuse could be the culprit that has stopped the windshield wipers from working. Check the fuse assembly under the dashboard of the car. Replacing a blown fuse might fix the problem of windshield wipers not working.
Windshield Wiper Sprayers Not Working - Things to Check
Sometimes the windshield wiper sprayer stops working which can be very annoying. The washer mechanism is a self cleaning mechanism for the windshield. Here are some of the things that you need to check in case it is not working.
Check Windshield Washer Motor
The windshield washer mechanism might have been impaired due to the malfunctioning of the wiper washer motor. Check if its working and get it replaced if it is beyond repair.
Check Windshield Washer Fluid Level
Sometimes the washer doesn't work because the washer fluid levels are not filled to requisite levels. Filling in fluid might restore normal functioning.
Check For Broken Washer Hose
The connecting washer hose that connects the reservoir to the nozzle, might be broken or worn out stalling the overall operation. Check the hose for leaks and get it replaced.
Check Washer Nozzle For Clogging
Last thing to check is the nozzle of the washer for clogging. An obstruction in the washer nozzle might be the reason for windshield wiper sprayers not working. Using a pin, clean the clogged nozzle. This might restore the sprayer to the normal working condition.
First try to inspect the wiper pc board, faulty solder connections that degrade with age are common in these vehicles.
SOURCE: windshield wipers won't work right
The windsheild wiper relay might be stuck or broken. Try tapping it with something or replace it. Could also be the the switch (lever that you control the wipers with) i hope this helps and good luck with diagnosing your problem.
SOURCE: the blinkers don't work.
I believe chryslers disable flashers when a flasher bulb is burnt out.
SOURCE: Wiper don.t work
Remove the wiper arms amd the panel between the hood and the windshield. There are teflon bushings on the actuater arms that wear out, they are cheap and available from the dealer but can be tricky to install because of the limited access.

Another potential problem with Chevy wipers is the circuit board that is located on the wiper motor- at least on mid- '90's pickups-. Due to vibration, the contacts can come loose and the unit will work sometimes, others not at all. The motor unit is on the firewall above the brake cylinder. Wiggle the harness with the key on, wiper switch on, and see if it have an effect on the unit working or not. If it does, it may be the contacts on the circuit board, a relatively easy fix if you have basic soldering skills and a small soldering iron or gun. Unplug the wiring harness, take off the cover to the motor contacts (3 torx head screws) and slide out the unit. Look at the contacts, especially in the upper left corner. If there are tiny black or discolored rings around the solder, which should be all silver, then the soldered joint has broken, leading to the malfunction problem. Simply re-solder these contacts, using reasonable care, and put the unit back in. Then try the unit.
