    So i just found out you cant put any freon into a prius.

    I just asked the parts store for the freon for my 05 prius

    and put in whatever

    It worked for a day or two then back to warm air blowing

    figured had a leak bought uv dye tried to put it in the system the gauge was in the red after I put it in green the last time i refilled it.

    That was about 3 weeks ago and ive been running the AC on full blast

    Is there suppose to be a specific light that turns on if the compressor is bad.

    Ik i will have to drain it out whats the best way for me to do that on my own.

    You have to have 134a virgin pure nothing in it not the freon that's the problem it's the oil you need nd11 oil it doesn't conduct electricity . Kind of similar to the oil in the transmission. The freon is regular 134a ND 11oil

    Don’t?

    seriously, I’d let dealership deal with it, disclose everything you’ve done as well. Show them the receipt for the “whatever” stuff, and the indicator dye.
