How to Fix the Mazda CX-7 Window Grinding Noise

Given below are some of the ways you can solve the issue.

1. Installing New Regulator

As we have mentioned above, the main culprit could be the regulator. So, if that is the case for you, do not worry. Because installing a new regulator is very simple. 

Things you will need:

  • Flathead screwdriver
  • Tape 
  • 10-millimeter socket 
  • Philip screwdriver 

Now that you have gathered all the items let’s begin. The first thing you will do is loosen the Philip screw inside the handle. After this look inside the door handle area. 

You will notice a plastic cover inside the door handle. Grab your flathead screwdriver and remove it. This will expose a Philip screw, remove it. 

The next thing is to remove the plastic cover beside the side view mirror. It can be popped right off. Then start pulling the door panel from the left side with a flathead screwdriver. 

With some force, you get the door panel off. Don’t pull too hard because there are wires attached to it. You’ll notice one connector to the door handle, just pop that right off. 

This will let you remove the panel a bit more, with more wires getting exposed. Just push the tabs of the wires to remove them. The door panel will then come right off. 

You will notice that the handle will remain hung, no need to worry about that. The next step is to tape the window glass so it does not fall. Or you can have someone hold it.

From the fully exposed insides of the door remove the window motor first. This you can do by removing the three 10-millimeter screws. Followed by pushing the tabs in. 

Now remove the main thing, the regulator. It is held on by two 10-millimeter nuts. Then untape the glass and push it all the way down. Remove the two plastic caps in the middle of the door that are holding the window. 

After removing the caps you’ll have access to two holes. These two holes are holding the window to the regulator. Push the regulator enough to where you’ll see white pieces in the holes. 

Those white pieces will have bolts that you need to loosen. And while doing this hold the glass up again. Then to loosen the regulator remove the screws. 

Now to remove the big black plastic pop the connector along the power lock actuators. Loosen the screws holding the plastic on the left side of the door. Then go ahead and disconnect the connectors for the power window.  

After you have removed all the screws. Put your hand behind the back of black plastic and pull it all the way out. Then remove the old regulator.

Then take the new regulator and put it in the place of the old one. And put all the 10-millimeter screws back into place. Do not forget to reconnect the connectors back. 

Same for the side view mirror connector. Then untape the window glass. And go ahead and slide it to the two holes that are in the door. 

Then put the rubber covers back into place. Then take the window motor and install it back into place. During this, you may have to pull your window up and down to get the gears to line up correctly. 

Now that you’ve got the motor back on. Get the door panel and stick it back into place. Don’t forget to reconnect the three main connectors first.

Then get the door handle back through the hole. Reconnect the connector that is attached to the door lock. Feed the small wire through the same hole of the door lock so that the door locks work.

Finish by pushing very hard on the bottom of the door so that the clips sit in place.
