Windsheld wiper arms not moving but wiper motor is still working

ANSWER : It sounds like you have internal damage to the wiper motor assembly. Sometimes the linkages break and prevent the motor from transferring motion to the wiper arms. To have this diagnose and repaired, a certified technician from YourMechanic, can come to your home or office to inspect the window and determine what fix is needed.

ANSWER : You can try to use a heat gun (REALLY carefully though, unless you intend to scrap your car) to melt any ice on the linkages to ensure that the linkages are not mechanically binding anywhere (due to ice; they can, of course, bind due to other causes). Of course, if it’s REALLY cold out, even that strategy is going to be problematic because whatever you unfreeze could instantly re-freeze. You just have to judge your circumstances or put the car in a warm garage for a short while. Heat gun or no heat gun, if you judge that there are no mechanical blockages, and you can SEE the motor turning, and yet the wipers aren’t moving, you could have stripped (broken) linkages.
If you cannot see what the motor is doing, the noise you are hearing could be the "humming" of a stuck motor, as opposed to an actually functioning motor. If you desire that the issue be diagnosed and the root cause(s) repaired simply request a non working wiper diagnostic and a certified mechanic will come right to your location and get this resolved for you. Please let us know if you have additional or followup questions.

ANSWER : You will have to replace the "wiper arm shaft" and/or wiper arm for the side which isn’t working. Both of these components have very small splines which interlock when the nut is tightened. A heavy snow or ice load can cause the splines to break down, or strip, rather than damage the electric motor. A certified technician from YourMechanic can replace the windshield wiper arm at your home or office.

ANSWER : Hi – the sudden nature of this failure would suggest a fuse or other electrical link, but you have checked the obvious. Further diagnosis is needed to determine which component in the electrical power chain has failed – switch, electrical wiring, or the wiper motor itself. I would suggest an electrical component failure by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

ANSWER : Hi there. Was supply voltage checked at the wiper motor, fuse, wiper switch? If there is no supply voltage at the fuse, then the problem could be in the fuse block or wiring harness. The fuse could have a crack in the link that is preventing voltage from transferring; check both sides of the fuse for voltage. If there is power on both sides, then check the same at the switch an see if it has voltage in and out. Again, a wiring harness or fuse block could be an underlying issue and will require the electrical wiring diagram and a digital volt/ohm meter to proper inspect. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a wipers do not work inspection.

ANSWER : The process can be very difficult and there is some steps that require turning on the wiper to intermittent and then measuring the alignment. You can search up "wiper transmission installation" for your specific vehicle and it should come up with many videos and procedures for you to follow. I cannot give a specific ones in particular since some have copyright blocks.

It’s pretty easy to search them up and follow them to fix it. However, if you can’t seem to get the help you need online and you’d like some assistance with the installation, contact a certified mechanic that can ensure that your wipers are functioning properly at your own convenience.

ANSWER : The problem you are describing likely stems from an intermittent electrical fault in the wiper circuit. The windshield wiper system uses a small electric motor to move the wiper arms that you see on the windshield. That electric motor is controlled through a switch, relay, fuse, and wiring. One, or more, of those electrical components has failed although it is also possible that the mechanical arms are binding (seized, if the lubricant has dried out) thus causing the electric circuit to the motor to overload. Regardless of the underlying fault, if you request a non functioning wiper diagnostic/repair, the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

ANSWER : You should replace the entire wiper motor assembly since the assembly will have a new wiper transmission and parking sensor mechanism.
