How the hell did you fill up with 134a Lol, the fittings for 1234yf and 134a are different

$1000 EPA fine for adding 134a even for private individuals lol. I've heard it works fine though if you drain it and just use 134a.

Well, I have bad news for you. If you've ran your A/C since doing this, your condenser is going to have to be replaced and your system completely flushed, compressor oil completely drained, desiccant replaced, etc. See, the problem is that R-1234yf system condensers have super small passages for the refrigerant to flow through. 134a will clog these passages and render your A/C system completely useless. Therefore the entire system will have to be flushed and the condenser, desiccant, maybe even the compressor will have to be replaced because it is nearly impossible to remove all traces of 134a once and it's compressor oil that was introduced into the system. Good luck.

According to this guy, he's had no issue with r-134a in his Civic for several years.

Sounds like it's time to throw away the car based on other commentators. Just drain it and refill with 1234YF, if it still gives problems whack a mole it step by step

I dont buy it for one second. In fact adapters have been made to be able to go back to 134a. Maybe there would be issues if you put 1234yf in a 134a

I mean I'm sure it's not good for it, but at this point just refill and reuse it. If its going to die its going to die. Worry about it when it dies.
