fan fails on all speeds, and all fuses good? Yes , yes? or no ,YES?
in what country. now), JS2 means car JAPAN maDE. ACTUAL)
where was car sold new?. that is first. NOT TOLD !
LEARN THAT PARTS ON THIS CAR ARE NOT THE SAME WORLD WIDE, OK? And some parts are even FIAT made.
in The USA , SUZUKI stopped selling cars.
first thing I will do for you is read HVAC page at alldata.com
see what parts it has and where.
there is no relay for speed, and that means if the relay marked #5 fails all speeds fail.
the relay 5 is in the J/B junction box. has only 4 pins and can be bench tested easy, SPST 12vdc relays are super simple devices.
and only 2 parts stores online now sell parts for suzuki
one in New jersey and one in CALIF.
lets say you said I live in calif and we play this game.
here we go .
go there, tell them your car facts make model
and the numbers on your bad relay,. and bingo.
