the blower is silent.????????? yes, sounds matter !
ON HIGH TOO? (fan speed max)????
or makes normal sounds, but does not blow.
1 or the other.?
the blower if dead silent can be hot wired (blows now?) (costs zero to do)
or using any voltmeter made. measure for 12vdc on the 2 pin
to motor, fan on high. (costs $10 for tool at walfart)
if 12vdc there, (across the 2 pins) then the fan is bad.
of 0v, the controls are dead.
the fan on most cars. on high, bypass the fan speed resistor block.
what you dont have is the schematic,
its at 2 places (usa ,min)
alldata.com
and suzukipitstoppus. (real fsm book)
2000 GV, data, below.... it takes all of 10sec to look.
all answers, USA cars, as this is a USA forum.
i click HVAC for you.
as you can see the switch is grounded at red circle.
and with fan on high ground (0v) is applied to the motor low pin
and if the relay is hot, (2 fuse good) the output of relay b/w wire
will be at 12vdc, if not the relay is bad.(fuses good)
cant be more simple. same from 89-2000 after that things get harder, (controls) your car has a motor driven mode damper
that is why i asked the sounds questions. as it too can block the air flow. (with a perfectly running fan)
