Check the Resistor unit.
This stops the blowers working ,
sometime number 1 on the heater switch will but nothing else .
No 2/3/4 working on heater switch.
Pic of the Ford type attached.

if it dont blow on high , it can only be 3 things. (wires are always suspect and conn.. in all electrics.)
1: blown fuse.
2: bad switch (see link, below for how to fix THIS switch.)
3: bad blower motor.
there are 2 ways to find it, not guessing...
A: use a voltmeter, Got 12vdc to motor on fan?
no ? then got 12vdc into switch? yes, then switch is blown
B: hot wire fan, work now, yes, motor good.

most cars call this blower. (new cars have up to 5 fans)

these Suz, dont have spare switches now, for many older year cars.
see list above for p/n of the ones they do, this is one of the hardest
parts to source on zuk and some have CAMI switches and others have Japan real . (production options..)

If you are talking about the belt for the ac compressor, yes the heater should still work.
If the blower is not working, you will need to have the blower motor checked for voltage and ground.

try resistor...

The blower motor resister has gone out,it is next to the blower motor,and the blower motor is bad to,this blower motor was drawing to many amps,and has burned out the blower motor resister.

You might have a bad speed selector switch, or your blower motor resistor is faulty.
