Wipers only work on slow intermittant
front or rear, guess front... gee?
you meant fails only on high and fails means dead, rigth, not slow on high or some other odd effects. like noise. chattering or ?
what does it do on high , i guess sits still.
the wipers can be slow. if the motor is weak.
fail to return
make noises. or jam.
Q1:" do the washers work
there are 3 things, POWER< CONTROLLER and MOTOR.
the first question here, is this computer controlled (eg BCM)
answer: YES, the BCM does keep alive. (more later)
is there a relay?
the control has 10 position.. off 1....9
so intermattant 1 to 5 work, you never said that.
at pos. 6 is low, works.
at post 7 high its dead. it turns on the HIGH wiper relay in the PDC
so that is dead,
my guess. i use meters to tell me facts but if i hand to guess
it be the HIGH relay blown.
if not its the H tap pin on the motor bad.
or wires to same.
the wiper motor can be hot wired to test it. easy
pin 6 on the motor connector is hIGH./
if how ever the high starts the wiper moving and then dies
then the PCM keep alive feed is dead. or wiper on./off is dead.
but the other work, so id skip this.
try to say exactly what happens on high. (DEAD?)
OR MOVES AND STALLS.? O short strokes.?
