Cause it didn't work when i bought mine three years ago. then i had it identified and it was contaminated and no shop would take it. So i did the typical JDM ricer thing and removed it all. except the evaporator in the dash. And now that i have been federal and ASE certified in Heating and A/C for two years now i really kick myself in the ass cause i kno how easy it would be to overcome those earlier issues. and i really feel the need to have A/C sometimes. 100 degrees stuck in traffic w/ the tops off really sucks sometimes.
and i threw away all the parts cause i had no room to store them anymore. so little by little i have to buy one piece at a time.
