- AC blows hot air only
- HVAC unit appears to be working correctly, snowflake is visible on display, tested system on Lo and fan on high
- replaced fuse E7 and D6
- the AC is blowing air, the blend doors open (can hear them)
- hissing noise coming from the AC vent as well as from the condenser pipes in the frunk (sounds like an air leak) but I can't find source
- both condenser pipes are hot to the touch
- system holds pressure at 25, recharged the system with 30oz r314a but still no cold air

At this point I'm thinking it's the compressor - how can I verify/test? Anything else I can lookout for that will help narrow down the checklist?

Hello,

are you shure you know what you are doing? Sorry, if i sound harsh, but if you've looked a Youtube video with some guys refilling their AC with some refrigerant and telling you know its working that doesn't mean it will work for long. Just my 2 cents.

The AC system needs 850g of R 134a and also it is extremely important to add refrigerant oil 195 +/- 15 cm3 ND8. If some of the refrigerant is missing the system won't work. If you have to much refrigerant in the system you'll ruin the compressor. If some of the oil is missing you will ruin the compressor immediately.

So do yourself a favour a let the refill be done professionally. System leaks can be found easy if you use a professional refill machine. Also if the system was empty it is highly recommended to change the dryer cardridge.
