the service manual covers all this , get one?
USA car? no told. answering for USA only. cars, sold here.
causes, all.
when drivers window motor fails do any others fail too?
the master controls what fails there, and each other door.
1: shorts make the thermal breaker trip.Fuse CB
2: bad motor overloads the supply
3: bad switch.
4: any wire bad in the path from power to motor. bad. open or shorted.
there are 3 pages in the manual for windows power
fuse 4/15/16/17/19 . all for good not blown./
delay relay not bad. SJB logic runs said relay
if yes, a windows now have power. 12vdc to all door locks and door windows. so this must be good. or locks fail too.
now page2 schematic
widows that fail for up and down or both ? sure stuck up, pain.
ID say with such gross intermittancy, but not sure total me.
the master switch logic board is no good.
that board PIN8 is power. red/LB color
if it has 12vdc at windows fail the board is bad.
if pin 8 fails the source is bad raw power from delay relay dead.
then.
oops 1 more , test, door lockout. turn it enabled. so other doors are dead, Kids mode.
this proves other door can not cause driver door to fail ,ever.
that main board has CPU, not sure why me?
but it controls driver up/down. relay on IT.
board pin 12, ground must be 0v at all times or fail hard it will
the windows cut switch kills ground to all non drivers windows
now that is a great test feature of all. and LED status.
top right is LED, if the LED goes dead power to the board is bad
that be #1 first thing to see. see resistor top right it is LED cut off...
