But, what is everybody doing about the electronics? I got mine working and all, only thing i need is another electric fan since it stops cooling after a few minutes of idling, but if i remember correctly i had to bridge some wires, and the way i have my a/c running the a/c compressor wont cut off under wot whereas on the r33 it does, at least that's what i understand. Or is everybody just running an a/c standalone system? Do those even exist? xD
On the 97-98's the AC system works differently
It stops cooling likely because its not cycling, there isn't an evap temp switch on the 97-98's. The 97-98 uses a variable displacement AC compressor from what ive read.
The 95-96 240's use a temp switch in the Evaporator, this interrupts the signal to the compressor clutch relay when the temp gets cold enough.. which is how most AC systems work including the r33 GTS rb25 compressor.
Check to see if it cycles, it shouldn't if its a 97-98 unless you've modded the system to. most AC compressors will cycle on and off around 41 degrees at the vent.
