thank you for saving me with this vid, I thought my reg. was busted!

Was there a trick to getting the evap box clamps on when reinstalling?

2:00 what’s the clamp called. I’m missing that in my Miata so I get no ac I need that clamp

I made a video on transmission stuck in reverse if you ever need it. Thanks for this video. Incredible how well these little cars hold up.

This is what ive been looking for! Thanks!

Finally a video of doing this if been searching for ages thx man you are the best and well filmed 👌

Hi, thanks for the tutorial. I have a weird metal “wire” sticking out from outside the black box (where the two green wires plug into the outer shell of the box” and it runs inside and is just shoved in between the fins of the evaporator. Is mine in a weird spot or is that where it should be?

Thank you! Last night the driver's side power window couldn't be opened and today I have been able to repair it following your advice. In my case the plastic melted around a contact and prevented a swing from doing its job. Thanks so much indeed, Giovanni MX5 NA 1991 SE BRG

7:24 what did you do to solve that problem? Mine is just 5cm too short

Fixed my window today, thanks to this video, thank you!!

Very good l

Instead of struggling with the cable attachment to the regulator I put a clamp between the slider and the top of the track and pulled the cable assembly together to allow me to put the cable around the wheel at the top and put the plastic clip in place.

The oem part is B00143029 black but any after market will work like Moss Miata have them in kind of blue for 4$

At 8:16 your finger is pointing at a roller that's affixed to a post on the regulator. Is it possible to replace just that piece? Mine shattered and ended up in the bottom of the door.

I know this is a decade later but what did you do with the two grommets by the firewall on the evaporator core? They're the two things you thought were foam at the beginning. Did you remove them?

do you know what bolt size is that bolt on the accessory belt tensionor? not the long one but the one that tightens the tensior to the bracket

03:08 oof

Were did you get the rollers mine was gone.

I don't know exactly where it goes cant really see in the video..where?

What are the odds

Thank you exactly what I needed help with Swedish Miata owner

My 1999 Miata with tan interior had exactly the same problem with the passenger side window stopping a couple inches down. Found exactly the same cause; plastic cable positioning clip popped loose, allowing cable to snag the window on its way down. I fixed mine by drilling two small holes either side of the cable close to the loose clip. I threaded stainless steel safety wire in one hole, around the cable out the other hole, then twisted the ends together using pliers. I like the zip-tie idea mentioned in other comments. However, mine was repaired, working, and back together before I scrolled down to read them. albumartist is absolutely right about that black sticky goo getting everywhere! I strongly advise wearing disposable gloves and clothes you don't mind getting stains on. Pay attention to which parts have to go back on before the plastic vapor barrier, because you don't want to deal with that goo more than once! About the same time as the problem covered in this video, my other power window suddenly quit altogether. Quickly isolated the problem to the a tiny broken bit of plastic in the window control switch in the center console. That too was an easy fix. I replaced the switch assembly with a *brand new one* found on eBay. I don't recommend getting a used switch assembly, because the plastic would be just as old and weak is the failed one. So, a big thank you to albumartist!

You cheated you have to show the process

Such a cool character .. Well done! 👍

My face curled when he laid the wrench on the lobes lol

I am all about quick and EZ, but you're gonna nickel and dime your Miata???

Best video thanks i been looking for this one

Do you need a new drier to convert or can you keep the stock drier and run r134a through it

I'm told I just need a clutch (it's a little noisy) Is it possible to just replace the clutch while the R12 system stays intact? my 91 NA is supercharged with very cold original air. 94k miles

Thank you for the videos that is a lot of work! How is everything working presently in June 2021?

Thanks for showing how to do this! I ordered OEM replacement cables, they are still for sale. Bike shop is still a good idea and probably cheaper but if your cable is broken, just know that they are for sale too!

No joy for me :-( I was afraid to try to pry out the switch, and being an automatic with overdrive, the console removal looked more complicated than it is for a manual. So, I took it to my mechanic. To add insult to injury, the Check Engine light came on on the way to the garage. A needed emission repair. Anyway, he called me to tell me he had the switch out if I wanted to try to clean it. I got the switch, which looked different than what is shown here (this is a '99 Miata). I got the switch apart but there were no exposed contacts. Each lever moved a separate small sealed slider switch. I gave him to go ahead to order a new switch. This is going to be $$$$$$$$$$$$$! :-(

Did you flush the system prior to attaching ? Finding conflicting advice

Can you switch a glass window to that top? A top that used to have a plastic one?

Thanks for the video, those gloves are top notch! 😂

i can not seem to keep tdc wile taking the harmonic balancer bolt off i cant even get the bolt off its stuck do people really keep the wrenches on the cam lobs to keep the engine in tdc

Just bought my 91 a few days ago and I’ve been searching nonstop for a fix. Thanks !!

lol I have the same color and the exact same thing just happened to my car on the drivers side. I pulled off the door today and was like you couldnt find a thing, i can only lower my window about 2 inches and it starts kicking backwards. I also noticed my stoppers on the upper part of the door were in the bottom of the inner door panel crumbled apart but I found that same white plastic broken piece and still dont know what that goes to. Thank you for this video I know two things to go directly to and check tomorrow. I really appreciate it man.

how long did it last?

Thank you for this video. I know it’s old, but it told me two things. This is a common problem on these cars and that I could fix it. My problem was exactly like yours. Wire was binding the window. A push of the bracket back in the door and a little duct tape and it’s working again. I wish you would have shown putting that plastic with the goop back on. I did my best but it was messy. I also had to drill out the door handle screw. It was completely stripped. Although my bushing like yours is in bad shape, the window worked fine without it. I did not want to also remove the glass. I guess that is a project for another day. I’m just glad to have a working window again.

Oooo fancy.

What brand and where did you buy your expansion valve? Great video by the way.

It pains me to see you using crescent wrenches and channel locks on these soft fittings. Use proper line wrenches!

This is among the best Miata tutorials on Utube. Thanks for all the effort you put in it! I just shared it with a neighbor who is replacing his evaporator after I used your vid a month ago - AC on my NA worked great but drain plug had gotten blocked and would not stay clear (had to drill hole in floor as stop-gap to keep it from flooding...) I replaced the 30 year old expansion valve as a preventative. While I was in there, I diluted 4 oz of commercial Koil-Klean with an ounce of water and sprayed the coils (they were black and slimy) Scrubbed the crud out with a coil brush, then sprayed and dry-wiped everything inside and out that I could reach using Rectorseal . Once the box was re-assembled, I wrapped all the outside panels with Home Depot adhesive backed silver duct insulation and covered the low side lines in the engine compartment with rubberized pipe insulating tape. AC is at a steady 36*F on the center vent fridge thermometer today when OAT today is 90*.. (Part of what makes it so comfortable inside is that I covered the firewall, interior, door skins and trunk in generic dynamat; headers were jetcoated and I mirrror polished stainless steel to replace all the heat shields. Interior stays fairly cool even without AC - total cost for all the NVA mods was right at $300 including a new drier and a local body shop doing the AC draw-down and recharge on a slow day ($48 an hr x 1.8 and I provided freon, oil and a case of beer.... vs $125+ at a repair shop).

I wonder how long that lasted

What were the symptoms that prompted this repair? My miata AC is not blowing cold. It is charged and compressor+fan working, AC lines under the hood are cold, however every 5 seconds the flow of refrigerant changes (becomes lighter in color when looking through the sight glass). I am assuming this thermal expansion valve is sticking causing the refrigerant to not make it all the way up to where it needs to go?

I.just did mine with plexiglass. It looks awesome!

2:25 autotune!

She sounds really healthy! Not much of that annoying ticking sound at all

This is the hard way to do it and why the book rate is so expensive.
