Fan dead, ACC dead...help please
 

Hi
I recently bought 1992-1993 850 GLT (made Nov 1992 in Belgium, 1st registration 1993), actually I bought 2 of 850GLT cars.
I found it difficult to buy Haynes workshop manual (I emailed Haynes Australia - they just ignored me, bastards) and so I hope somebody can give me some tips...?
Cab fan (in front of passenger) is not working at all, air cond is not working, REC and ACC OFF lights keep blinking. I checked all fuses - they are OK. Where to look for next ?
Also I would like to know if that is possible to check-replace main bearings shells, without removing the engine ? I expect to find some of them a bit worn (232.000km, some limited noise and vibration, I am still not quite sure where is that coming from but I expect main bearings).
Thanks for help in advance
