Well after about 4 years of not having air I have decided to have the A/C fixed in my 93. Car only has a shade under 35,000 miles on it and still runs/looks great. But in Houston no air is brutal. Friggin repair is 2k though. Of course that is dealer, but don;t know anyone else that can fix the d*** thing.

Is 2k a bit much or is that about right for a 93 touring?

It all depends on what's wrong, and what needs to be done to fix it.

Do you even know what's exactly wrong ?

FWIW, on some Mercedes replacing a leaking evaporator can cost $2K-$3K. . .

TIA,

I have the est at home, but it was not the evap core. Just about everything else evaporator. Valves, expansion valve, drier, R12 (damn that stuff is getting up there) I am sure the repair is a premium cost. But, like I said. Where else.

Find a good A/C shop. It's like transmission work - the dealer can do it, but they don't necessarily have the expertise and affordable parts.

Right now might be the worst time to get it fixed, since in PA the A/C shops are completely booked from Spring through mid-summer. You may get more options/better service by waiting until a lower demand time of year.

BTW: I HIGHLY recommend using the ES-12 refrigerant (not the Freeze 12), it is a drop-in replacement for R12 and I'm VERY happy with it here in Florida.

I've converted ALL of cars to it.

I have a 93 touring. just had the entire system (except for the hoses) done for $1,100 with all new parts - I have a friend that owns an a/c shop in Round Rock (just north of Austin). This was definitely a friend price and he happened to have a few parts OEM in his storage room. This is actually an honest shop. Parts are outrageous and it was very tough for him to find the correct compressor (new). The criminals at the mazda dealer wanted over $500 for 2 hoses alone. Dealer quoted me almost $3,000 for total repair. I kept the R 12 - -holds under 2 pounds of freon so cost of the the R 12 is not a concern on the RX 7. Repair shop is ABT - 512-388-1977

If it needs a new compressor and a few other parts, and is a Nippondenso system (probably so since it is a 1993 touring) that is probably not too far from reason. Last I looked, a Nippondenso compressor from Mazda was over $1000.

On the other hand, if it doesn't need a compressor, and has just sprung a leak and needs an o-ring or two, a new dryer, a good vacuuming then a recharge then $2k is too much.

I would agree that you at least should get a second opinion from a shop that specializes in A/C Repair on either foreign cars or does a lot of installs on classic/collector cars. There's nothing particularly special about the systems in our cars other than the fact that it is all stuffed into a smaller than normal space.

Im getting ready to pull all of my AC stuff out of my 94 base. Mine only has 56,000 miles on it and works great. So if you want spare ac parts....PM me.

Parts for the Nippondenso system aren't interchangable with the MANA system, so if you're buying/selling A/C parts make sure you're matching the systems up properly.

The foregoing is true, however; the compressor is the one and only part that is directly interchangeable. Both use the TV-14, IIRC. And fitment is the same.

Note that the '93 base & R1 models use the MANA system.

Is it a broken hose, or a leaky evap, dryer, condenser? You can fix most of that stuff yourself and just have it recharged, assuming there is no pressure left in the system, or you don't care about venting the refrigerant to the atmosphere...(illegal I think)

Went ahead and authorized the dealer. They have always done good work on my car ($7,000 worth when it was flooded during TS Allison in 2001). Hopefully it will blow frost when they get done with it.

Interesting. For some reason Mazda lists two different compressor part numbers (with two WILDLY different prices). I realize they are both the same basic Nippondenso TV12/TV14, but are you sure that the fittings/threads for the refrigerant lines are the same?

Got her back yesterday. She is blowing frost in the hot Houston summer. Drove her all day yesterday. Car still turns heads. You can still see reflections in the paint. I rolled 35,000 miles yesterday. Damn I still love that car. Driving it made that 2000 bones on the A/C a little less painful
