Sometimes the wiper linkage seizes and sometimes a worn link will become detached, leaving the motor running but the wipers unmoving.
It is very rare a wiper motor breaks but the switching for the self parking wears out.
Other than checking multiway connectors haven't worked loose there is little you can do without checking the supply, ground and switch and that is made much easier when there is a wiring diagram.
If upon turning the switch, you hear either a buzzing or a noise coming from the wiper area but no movement of the windshield wipers, then it becomes likely that there is a mechanical problem. In front wiper systems, there are two moving parts, the wiper motor and the wiper transmission. In rear wiper systems with a single wiper, there’s a single moving part, the wiper motor.
If you hear a buzz, it could be a motor straining to move a jammed wiper transmission or a locked motor gear. If you hear a grind coming from the wiper area, it could be a stripped gear in either the motor, the transmission or where the wiper arm splines to the wiper motor in the rear. Don’t let the term transmission fill you with dread; it’s simply a term for a multi-lever set of arms and hinges that turn the circular motion of the wiper motor into the side to side motion of the wiper arms. It is also possible that the spline on the post of the front wiper arms is stripped.
Generally speaking, you can reach the motor and transmission by removing the wiper arms, all the screws that hold the cowl beneath the wiper arms and the weather stripping. Once exposed, you should be able to remove the motor from the transmission and check to see if the transmission is binding or if the motor is the culprit. Simply, replace the culprit, and reassemble.
If the problem is with the rear wiper system, getting to the wiper motor can be more difficult with far more trim to remove than with a front system. You may elect to consult your mechanic for help.
check the backside of the fuse cover and there are 2 spots for fuses in engine compartment and under the dash Please rate my response thank you very much
The motor is usualy central to the wiper arms and either bolted to the firewall or inside the plenum chamber at the bottom of the windscreen.If you can hear the motor you can find it, track it down by listening.Your probly right about linkage however if that is the case you should be able to move the wipers with your hand and they should move freely if they dont you may have other problems.
