Window Bang/Skipping Gears?
I have a 1998 Mustang that had a window motor go out recently on the drivers side. Long story short, I replaced it myself and it worked fine. However, after a couple days it started making this noise: https://drive.google.com/open?id=1Mq...9IOPV5y2smw2EA
It seems like it's skipping gears when it should be stopping at the bottom or top of it's track, and I was just wondering what part of the power window system controls when the power window motor stops after it feels resistance? It seems like I need to replace that part. (The motor itself is brand new) Thanks for any feedback. |

Re: Window Bang/Skipping Gears?
Did you replace only the motor itself or the entire power window regulator assembly?

Re: Window Bang/Skipping Gears?
Most window motors don't turn off when they run the regulator to the limit. They just keep pushing until you let go of the button, or the internal thermal switch heats up and blocks the flow of current.
In fact, some window motors stop working b/c the thermal switch malfunctions, turning off the motor when it is opening/closing the window normally. I have bought a couple of rebuilt/refurbished motors that "fixed" the problem by disabling the thermal overload switch, but these motors burned up when the control switch got stuck in the on position.

Re: Window Bang/Skipping Gears?
The thermal breaker is shown as being internal to the motor assembly according to the factory service manual. So if the thermal breaker is not tripping, it's probably due to the motor you installed not having the feature. Did you get a "universal" motor or a motor specific to your application?

Instead, my guess is the regulator gear, tape, or the worm gear in the motor is skipping. I noticed that your video only shows it making the noise when the window is all the way down. If it only makes the noise when it's all the way down then my guess is that the regulator is damaged, but I'd still check that every thing is tight before buying a new regulator .

It should be worth mentioning that the motor did stop when it hit the bottom/top normally for a couple days after the install, so it does have that feature. |

Re: Window Bang/Skipping Gears?
The "regulator" is what the motor attaches to, and what attaches to the window. A new "regulator assembly" would come with the motor already installed on the regulator.

Re: Window Bang/Skipping Gears?
Actually, you can purchase a regulator without the motor for most vehicles. But yes, the regulator is the mechanism that the motor drive "pushes" to move the window. Go to any autosupply website (I like RockAuto.com) and look up the window regulator assembly for your vehicle and you can see what we're talking about.

Re: Window Bang/Skipping Gears?
I took a look a photos of the regulator for the 1998 Ford Mustang. My guess is your noise is caused by something that is loose.
It appears that there is a torsion spring on the regulator that increases tension as the window lowers. This is probably there to help the motor push the window back up. Since your motor is making the popping noises when the window reaches the bottom of travel, my guess is that the spring tension is increasing the forces on the motor to the point where the motor gear is slipping out of the regulator gear. If you assembled the motor to the regulator with screws, then they may have worked loose, or if you used rivits, they might not have been tight enough in the first place. |
