"I undid this bolt, and subsequently lost it..." Ngehhhh I hate that so much... Haha Thanks for the video upload! Helped out a lot

Thank you so much for your videos! Really helped me understand all the a/c components and vocab because I usually stay away from the a/c system instead of fixing it myself. My ac compressor just went out on my 94 Miata -__-

Well sir, i dont have an AC System to begin with in my European NA. Im now on it to add it on my 95 NA. Wiring needs to be placed in my Harness i transfer it currently since the Wiring Harness of a US oder CAN Miata are inconpatible to European Models. Sadly.

Yes. It is on the Christmas list... along with another Miata.

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

[@markc4768]

you can indeed replace the clutch on the NA without compromising the system. However, the most common cause for clutch failure is too little or too much charge causing the compressor itself to become loaded and overheated. Another issue is that early Miatas that are still running r-12 should be using PAG 150 and those converted to r134A are usually done via the quick and dirty method (either the r-12 has leaked out or was drained to the atmosphere. This doesn't get the old oil out of the system and the addition of 134 simply creates a system that will eventually kill either the compressor or the clutch. Thus, if your R12 system was professionally serviced or professionally converted to 134a, replacing a clutch that is chattering or making a whiney noise will probably put you back in business. However, if it was shadetree'd without a good evac and the correct oil (mineral for R-12 and PAG46 or 100 in very hot climates for 134A) I would recommend taking it to a body shop that's in a slow cycle.... they are far better priced that most dealer/mech shops, and usually have more experience with AC problems.... I dealt with exotic and collector car shops for 20 years and had them do all of my AC service ( vacuum recovery, replacment O-Rings, system drawdown and integrity test, then add oil and recharge system. Save at least 30% or more over a dealer service.
