Inspecting Power Window

On a '91 Miata, is it difficult to take the door interior cover off to just inspect the mechanism? I'm not talking about dismantling the power window itself, but checking to see if there is a problem that exists. Also, can you work the power window with the cover off, while its exposed?

No. Look at Miata.net for power window installations.

Yes tiy can.

Also, can you

If it's like my '90, you just pop off the speaker cover (pull up gently to release the clips), remove the door handle and armrest, the pull out gently on the interior cover to release the clips and slide up towards the window.

Your most common problem with the window will be dirt and gunk built up in the window guides/channels. That usually makes the window run slowly. Unfortunately the best way to clean the guides is to remove them and that gets into taking the whole damn door apart. The Enthusiast's Shop Manual has all the instructions, complete with photos.

But it's a good idea to keep the tracks cleaned and lubricated or you'll end up replacing the regulator and/or cable.

I just replaced the passenger-side regulator 'cause the cable snapped and pieces disappeared. Took about 45 minutes.

Was any of the plastic guide wheels of the tracks destroyed, as is suggested can happen somewhere on miata.net?

My windows really have problems, but I hesitate to take the door apart any further than to the transparent plastic. OTOH, spraying in lithium grease from the top is not really effective.

The wheels had flat spots and cracks. From what I could tell after the fact, it appears that one of the wheels hung up, which snapped the cable and sent the plastic piece that used to be on the cable into parts unknown.

And a really good place to lube if you can get there without taking everything apart, is right at the top of the assembly where the cable guide/stop block come together. It's at the very top of the window guide toward the rear of the door.

If that part hadn't vanished, I might have tried replacing just the cable. However, I was fortunate enough to get a whole assembly thru a friend, who had *just* bought it from e-bay! He's going to convert the non-power windows into power windows on his Laguna so his was not an emergency need and he was kind enough to pass on the part for the same price he paid for it. $52.90 - including handling. A heck of a lot better than the nearly $205 the dealer wanted!

That was what I was afraid of.

Thanks, I'll try that. I do not have time to really fix things right now.
