Air conditioning blowing hot air

[stefastn]

My AC started blowing hot air and then no air at all.
Took it to the dealer and they found that the low temp circuit coolant pump had seized.
The low temp circuit pump pumps coolant to exchange heat with the AC freon.
Since that particular pump had seized my AC went bye bye

How did they come to that conclusion that the pump had seized, was the coolant not being used?

I need all of you to re-assemble here like the avengers please. Having the same problem, my pulley belt snapped took a chunk of the ac compressor pulley with it. I got another compressor from an M340 installed and the clutch on it does not engage, ac still blows hot air but the pulley spins just fine. I went and got a compressor from RYC for $300 and put it on and it imploded (broke) the next day. I have spent so much money and time trying to fix this, currently 100 degrees in South Florida, all black supra. I am DYING. WHAT DID YOU DO TO FIX THIS!!!!!!!!!!!!!!!!!!!!!!!!! AC shops telling me its a signal issue since the compressor is getting power but just not getting a signal to spin clutch when ac is turned on, theyre also telling me that my system is contaminated and I need to replace the condensor. I spent $500+ on a vacuum & recharge, $200+ on 1234yf, $300 on a compressor that lasted not even 24 hours, $200 on a used condensor from a Z4 not installed yet, and countless hours on installing and reinstalling the compressors, belts, etc.

Dude…….. you gotta find a reputable place that knows what they’re doing. Some good on hands diagnostics. My fav shops told me he could screw around and muck with my MX5 but… it wasn’t an easy leak or fix that I needed after he did a couple diagnostics and leak tests. He recommended I take it to a really good AC shop that he knew. Despite me needing it replaced ?, it was the right advice. If you’re in SWFL, hit me up and PM me. I’ll give you the info of the AC shop I used. They were quick, good, accurate, honest and compared to book value, affordable.

Hey gang!

There was a coolant pump seized code when the dealership scanned my car.
But there was no check engine light, it was dangerous as hell because my Intercooler temp could have been terrible.
The low temp circuit coolant pump was broken!
Once the low temp coolant pump was replaced, the dealer recharged my AC and everything has been good for a year now.
Knock on wood praise lord Jesus
