Directions on changing wiper motor. try wipers and hear motor run but wipers do not move. thx, chris

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.

Can you move the wipers by pulling on them? If you can and they easily move, the wiper linkage is disconnected. If you can hear the motor run and the wipers are inoperable, suspect a seized wiper pivot

the inside of the wiper could be stripped out and have no tension to move the wiper try pulling it off and changing it if not need to see how to take it of and maybe the motor could have stripped the gears inside itself.

It Sounds Like, Either The Arms Are Loose ,If You Can Hear Something Moving Behind The Dash,
Or The Linkages Are Seized ,If The Motor Just Hums No Movement Heard,In Which Case Try Spraying Q 20 On The Linkage And Try Moving The Wiper Arms By Hand To Get It Going Again,
If Not The Motor May Just Be Burn;t Out.

Check to see if the nut is tight on the wiper down at the bottom, secondly turn the wipers on and put your ear down by the wipers to see if you can hear the motor moving. If you hear the motor moving the arms under the plastic sheathing have seperated. Try the nut first see if that fixes your problem then try the rest.

if u hear motor not elect problem -most likely linkage unbolted from motor with motor running try to move the wiper arms if move freely than need to remove cowl and check the linkage hook up to motor -if wipers dont move freely than possible motor damage/seized linkage damaged but still would have to look under cowl at connection at linkage

either linkage broke/ jammed or motor is stuck -makin noise but not movin open hood and with wiper on feel motor- its on firewall-for movement if moving turn off motor now try to move wipers if move freely than they are broken off or have disconnected from the motor need to remove the cowl to access the wipers linkages

If indeed you can hear the wiper motor running but the wipers are not moving, there is a nut under the pivot point cap that has to be tightened. If you don't hear the motor running than you'll have to check the power to the wiper motor and the fuses. Good luck. Dana

it sounds like the wiper transmission has broken/slipped off of the wiper motor. Remove wiper motor and check wiper transmission.
