So heres another problem I'm having with my 92 gs that has the b18c1. The radiator fan never turns on. I have tested the fan from the battery and the fan works. The temp gauge runs very close to the half way mark (how bad is this?). However the condenser fan turns on like the radiator fan should... Where do I start with this problem??

So far I have:
-replaced the radiator fan relay
-recently replaced main relay due to another problem
-replaced the fan switch
-checked all fuses and they are in good condition
