Electrical problem
2002 Nissan Sunny Automatic 123000 miles

One fine morning I have found that my Car's A/C and radiator fans (both one for A/C and one for engine cooling) was not working. I have checked all the fuses but found ok. Any help or hint will be highly appreciated...Thanks in advance :-)

BMRFIXIT,

I checked the relay box and found that after removing the radiator fan relay and shorting the first set of contacts found that engine fan works fine and if shorting the second set of contacts found that only A/C fan works fine but not the A/C.
