How do I get this thing working, it's over 100 here now and I've pulled the evaporator twice. Nissan want's $513 for the evap. core, say they only have 5 left in USA and not making anymore. Any advice will be very much appreciated. *Gonna pull the evaporator again tomorrow and see if I missed anything, oh yeah, system has been converted to 134a, prob change expansion valve again just in case bad one, and new drier (every time I break a line). Anybody know of a sensor or anything on the automatic a/c system in this car that may be my problem, already checked heater hose valve and heat exchange door. I'm already hooked on this car (wanted one for a long time) and it's killing me not to be able to ride in the daytime in it.he he Should I convert back to r12 Might try it as a last resort.
