I was in the process of charging my A/C system in my 90 when the cooling fan and the A/C clutch stopped working altogether. While I was charging the system, it did not seem to be taking the refrigerant correctly, the clutch was cycling On/ Off at regular intervals without changing duration, and the motor started bogging down. After about 10 minutes, the clutch stopped cycling and the cooling fan stopped running.
As stupid as this sounds, I was having a hard time identifying what fuse protects the cooling fan when I found a bunch of info on the fuseable links. I still am not clear which fuses control the fan? I also don't understand why at the same time the fan quit, the compressor clutch also stopped cycling.
I checked other threads and verified the fusable links were Ok (I think) and that the IRCM was getting 12v power on wire #38 blk / org and the wire #57 blk was grounded. Could the IRCM have just gone bad? I have a 93 IRCM, can I swap it out with the one in my 90 to check it?
I also looked for threads about reparing the IRCM, does anyone know if they are potted or even if they can be opened and serviced?
Last question, is the IRCM for the SC different than a standard 3.8 liter t-bird? Thanks...
