i found this thread during a search, so i thought i would knock the dust off of it because i need to know.....
the temp sensor your talking about is the same switch any compressor has, it shuts off power to the compressor when the compressor hits a certain temp until it cools down....
i just had an AC guy tell me about orifice tubes...most AC systems, auto and home, have these things in them which are kinda like filters and they get clogged..he says they are under a dollar if you can find them...i just got off the phone with a nissan dealer, and he couldnt find one listed for my 87, but he mentioned an expansion valve that also gets clogged...it priced at 59 bucks....call your nissan parts guy and find out what your system has, they should know what to look for.....it could save you some cash at the ac service station if you have the part you need on hand..
does my 87 have orifice tubes, or just an exspansion valve???does anyone know anything about expansion valves?? my AC guy said my system is full, and everything else is working fine, i just need to get the clog out so the freon can move....i could get my ac back on track and only be out the part i have to buy, free freon is awesome!!!!
