The fan was dead before the work or after said work my other shoe drops./ ????????????????????? sure there is a relay , the fan uses huge current and no switches can handle that current, thus a relay, or like new cars a huge transistor.(aka, solid state relay by some) Not only that but this car has 3 fan relays ! rad fan.
first off, do you know how the fan works? i bet not. the fan is run under a complex set of rules. now. (saves fuel) the computer (bcm/pcm etc) runs it and only turns the fan on over about 225f temp or if AC is on , another temp. rules. so the test is covered in the FSM. book it tells you to idle engine until it overheats, (all do that parked) and then see if the fan comes on , at the stated temp. (tools) ok? simple no? x2 , its stated on the cover of the PDC. why not just look there, we dont know what engine you have.
im reading your FSM now, it shows a 2 speed fan. here is the wall of text, and clear. The engine cooling fan system consists of 2?electrical cooling fans and 3?fan relays. The relays are arranged in a series/parallel configuration that allows the engine control module (ECM) to operate both fans together at low or high speeds. The cooling fans receive positive voltage from the cooling fan relays which receive battery positive voltage from the underhood fuse block. During low speed operation, the ECM supplies the ground path for the low speed cooling fan relay which is fan?1 relay through the low speed cooling fan relay control circuit. This energizes the low speed fan relay coil, closes the relay contacts, and supplies battery positive voltage from the fan?1 fuse through the cooling fan motor supply voltage circuit to the left cooling fan. The ground path for the left cooling fan is through the series/parallel relay which is fan?2 relay, and the right cooling fan. The result is a series circuit with both fans running at low speed. During high speed operation the ECM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. The ECM grounds the high speed fan relay, which is fan?3 relay, and the series/parallel relay, which is fan?2 relay through the high speed cooling fan relay control circuit. This energizes the series/parallel relay coil, closes the relay contacts, and provides a ground path for the left cooling fan. At the same time the high speed fan relay coil is energized closing the relay contacts and provides battery positive voltage from the fan?2 fuse?1 on the cooling fan motor supply voltage circuit to the right cooling fan. During high speed fan operation, both engine cooling fans have their own ground path. The result is a parallel circuit with both fans running at high speed. When the request for fan activation is withdrawn, the fan may not turn OFF until the ignition switch is moved to the OFF position or the vehicle speed exceeds approximately 16?km/h (10?mph). This is to prevent a fan from cycling ON and OFF excessively at idle. end. quote.
and 3 fuses on the 3 fan car. FAN 1 fuse FAN 2 fuse and EmmisionDev 2 fuse seems one would check fuses first not relays,
this is for the USA car 3.6L engine., only. a 2 fan car. the ECM controls all 3 Relays. I have the schematic. ask
im not going to post the whole FSM diagnositcs pages. you can read it , any time you want for $4 at SUZUKI real.

and 3 fuses on the 3 fan car.
FAN 1 fuse
FAN 2 fuse
and EmmisionDev 2 fuse
seems one would check fuses first not relays,
this is for the USA car 3.6L engine., only. a 2 fan car.
the ECM controls all 3 Relays. I have the schematic. ask

here is the book,

Most fan and Ac relays are located in the under hood fuse and relay box. Adequately marked in owners manual or on plastic cover
