My wipers started sticking and I would have to turn the knob to get them to move. now they dont move at all.

If you can hear the rear wiper motor working but the wiper is sticking and not moving properly, there are several potential reasons for this issue. Here are some steps you can take to troubleshoot and resolve the problem:

1. Check for Obstructions: Inspect the area around the rear wiper blade for any obstructions or debris that might be preventing smooth movement. Clear away any leaves, twigs, or other materials that could be hindering the wiper's motion.
2. Wiper Arm and Blade Inspection: Examine the rear wiper arm and blade for any damage or signs of wear. A damaged wiper arm or blade might be causing the sticking issue. If there are visible issues, consider replacing the wiper blade assembly.
3. Lubricate the Wiper Mechanism: Apply a silicone-based lubricant to the wiper pivot points and joints. This can help reduce friction and facilitate smoother movement. Be cautious not to use excessive lubricant, as it may attract more dirt and debris.
4. Check Wiper Motor Linkage: The wiper motor is connected to the wiper arm by a linkage. Check the linkage for any loose or damaged connections. If the linkage is damaged, it may need to be repaired or replaced.
5. Inspect Wiper Motor Operation: With the rear wiper turned on, observe the movement of the wiper motor linkage. If the motor is working but the linkage isn't moving correctly, there may be an issue with the linkage assembly.
6. Wiper Motor Replacement: If all else fails and the problem persists, the wiper motor itself may be faulty. In such cases, replacing the wiper motor may be necessary.
7. Professional Inspection: If you are unable to identify and resolve the issue on your own, or if the problem is related to internal components, it may be best to seek professional assistance. A mechanic or automotive technician can perform a more detailed inspection and provide a more accurate diagnosis.

Remember to exercise caution when working around moving parts and electrical components. If you're unsure or uncomfortable performing these steps, it's advisable to consult with a professional mechanic or take your vehicle to an authorized service center for further assistance.

Either the splined knob where the main arm connects to the motor is stripped or the arm has become disconnected...Only a small nut holds the main arm to the motor..If it becomes loose just a fraction it will strip the splined knob where arm connects to motor...

sounds like the wiper control itself is playing up

there should be a nut at the bottom of the wiper arm possibly a plastic cover over the nut remove and remove the nuts while the nuts are removed grab wiwiper at the top and try to jiggle of stud at the bottom sometimes it helps to move wiper arm so it hinges or wiper arm is sticking up ,once removed set the wipers mabey 2 inches above the bottom of the window and tighten nuts

check wiper arm nut may be loose

will try to assist. when your wipers 'on' can you see looking from outside of car at the driverside wiper,is anything moving?look really close at the wiper at bottom near the wind sheild? is anything moving?do you see the wiper trying to turn?but just does'nt grab? if you see the knob turning,but the wiper not moving,maybe the wipers not pushed down onto the gear properly. try with wipers on,push the wiper arm down,or towards windsheild. does it move then? do you see the wiper gear moving at all? wiggle the arm,does it move on it's own? if so, you need the wipers adjusted.[autozone,advance auto parts] for free. if the wiper on drivers side,the gear that drives the wipers[little round] thing that wiper arm at the bottom of winsheild does'nt turn at all, the wiper arm under the dash in disconnected. this means that the panel outside where the wipers are will need to come off and the wiper arm will need to be reconnected to the wiper motor.there is a reason the wiper arm came off in the 1st place so that will need to be dealt with. it may be a faulty keeper pin,or a faulty carter key that holds the wiper assembly to the wiper motor.i really hope that this assists you,let me know please! and if you need further assistance,please repost your questions to fixya.com!

vehicle may have a stripped wiper arm.( remove wiper arm,turn on wipers & see if splined knob is moving ),if so turn off wipers & replace wiper arm.or if knob does not move then have to remove cowel & check linkage to wiper transmission!

Your wiper linkage has come apart or broke, you will have to take shroud on top of wipers and take alook

Turn the wipers on,and when they stop,peck on the wiper motor and see if they will come on.If they do replace the wiper motor,If they do not,replace the wiper switch.

there are little teeth on the connection if they are worn then you need to find out hoe to replce them
