2006 cobalt wipers dont move. but the moto is running, so how do i get to the wiper rod or motor section to tighten nuts or replace motor at please! please send a pictures etc. too me too. thankyou..

If you can hear the motor running, then check under the bottom end of the wiper . There should be a nut or screw to tighten the blade to the motor.

Sounds like the link rod has popped off or the wiper arm nuts need tightened. When the wipers freeze to the windshield and you start the wipers to clear the snow this will either strip out the wiper arms or pop the linkage rod off. Always pull the wipers away from the windshield before you start the wiper motor in cold weather to be sure they are not frozen to the windshield. Ok how to repair. Grab the wiper arms and see if they freely move in thier normal pattern with power off. Do they move independantly of each other ? If your lucky the nut holding the arms to the pivot just needs tightened. At the base of each arm is a black cover you have to pry up th see the nut. If not remove the wiper arms and inspect to see if they are stripped out. If they are stripped out bad enough you may have to replace them. If not then the linkage has popped off beneath the drainage grill. To see the link rods move look down thru the grill with the wiper motor running and the wiper arms off and you may see the rod flopping around. Now pry the plastic grills off, with the power off, left side first to get to the rod. Look to see if the plastic retainer in the end that fell off is still ok if so just line it up and give it a smack to pop it back on to the ball stud. If the shaft that is installed onto the motor is spinning but not moving the rod the motor must be replaced. Oopen hood and remove three bolts holding the motor to the firewall to remove it. Just reverse the process to reinstall. Thanks for asking at Fixya.com.

hi
simple fix, at the base of the wiper arm there will be a small cap which will pop out with a screwdriver reveiling normally a 13mm nut (somtimes 10mm) just position the wiper arm im the park position and tighten the nut. this will solve your problem

i just had this same problem with a cobalt. there is a nut. 8mmx1.25 it holds the wiper arms to the motor. you can hear the wiper motor turning, but the wiper arm if you look through the cowel, will not be moving. the best repair is dont put the nut that was on there back on if you can even find it. once you know you have it lined up, so the wipers will work properly, put some lock tight on the nut, and use a 8mmx1.25 nut which i know advanced carries, it also has a nylon piece that will hold the nut on.

In view of the answer from jchaffcom I feel that if there is a Hex on the end of the Wiper Arm the Hex Nut needs Tightened. I have a 2004 Silverado and this is what happened to it. Simply tightening the Nut solved my problem. Try it and get back to me with the results whether good or bad.

I have 2007 only. please rate as solved if this is what you needed. good luck.

Flip the caps up from bottom of wiper arm to expose where they attach to pivots. There should be a nut holding them on, try snugging that nut up a bit & see what happens. if it helps, remove the nuts, pry the arms off, and clean inside where spline etc., is and re-attach arms in proper(same) spot and tighten nuts again, but be careful not to tighten too much & snap the stud.

Underneath the cowl cover, where the wiper motor is, there is a nut that goes on the back. Check and make sure it's still there. If it's not, save yourself time and aggravation and take it to a garage. I had the same thing happen to me, and after scraping my wrists up pretty good from digging under the cowl cover, I got it back on but the tab that tells the wipers where and when to stop was broken. I hear that's a pretty common thing. A service tech will have to reset the timing and/or replace that tab.

One side does not work? Can you move the arm with your hands? If so, look for a loose nut that holds the wiper arm on. Remove the plastic trim on the wiper arm base, and tighten the 12 millimeter bolt. Please advise if this helps.
