she exists but not in the fuse box and it controls the two fans.my diagram identifies it as vc 2245 but does not give a location.i can only assume its in the engine compartment somewhere. i have 92 ecoz wire diagrams but no diagram for the aircon.
but i see a mention of aircon fan on the the one of the diagrams tied in with the cooling fan relay.
from what i can gather,fuse f25 supplies power to activate the relay which is earthed by the temp switch.so if pulling this fuse stops the fans (if that whats running)then your relay is getting a signal to opperate or a short to ground somewhere
also when you find the relay if you can identify i think pin 9 brown and yellow wire (should be one of the corner pins on the relay) this appears to be the control or drive for the aircon motor,my diagram fails me at this point
if memory serves me corectly there is a main fuse box in the engine compartment near the battery which has large type fuses in it.locate this and pull fuse D, this fuse supplies main power to drive the cooling fans and they should defo stop.but dont forget to reinstall it as your cooling fans will not work and we dont want to nuke the head
if you could tell me exactly what is running ie one fan,both fans,compressor,everything.also what lights are on if any.
hope this is some help
ps just got your pm now
