I found this wire hangin out by itself near the receiver/drier. The A/C hasn't worked since I've owned the car but thats about to change in the next week or two. The aux fan has only come on once in over a year and that was due to prolonged idling after city driving so the coolant temp circuit activated it (gauge was reading about 100C).



This is where the line circled in green from the pressure switch joins the compressor wire.



And finally, I noticed this tube was cracked where it joined the plastic fittings. I duct taped one side and wasn't sure what the purpose of it was.
I was kinda thinking it was for recirculated air but I'm not sure.



And this is Dmorrison's picture for a reference on the hose (from his definitive evaporator replacement DIY).



Thanks for any insight.
