How to Fix a Window Regulator

I didn’t want to fix our cars window. I’d even called a “professional” to come do it. I’d done all the hard work for them, figured out the problem and procured the part. I explained what needed to be done and they were supposed to come out Thursday.

They no showed.

Actually, I ended up calling them late in Thursday afternoon and telling them not to come because we needed the cars at that point in the afternoon, so it would be a waste for them to show up. They assured me they would come by yesterday, in the morning.

Again, they no showed. To make matters worse, they have yet to call.

Not that it will matter at this point. I’ve already done the job.

After the jump is a description of the process I went through to change out the window regulator for a Toyota Matrix. No pictures though. I don’t think they’d be very helpful.

Prior to the instructions, for the curious, the window regulator is the mechanical portion of the window lift. It is basically a scissor with one of the arms fixed to the door so that the other, which is connected to the bottom of the window glass in some way, can raise and lower the window. A motor is attached to the “handle” side of the lifting arm. I believe the scissor arrangement also gives some mechanical advantage to the motor for lifting purposes.
