Hi all,

I have a 90 r1500 w/350 burb that does not believe in obeying the wiper
switch.

First off it never parks. I use the mist function to stop the wiper.

all intermittent levels are the same -lo. at least until it gets tiered then
it stops.

hi and lo work properly

What is the best way to diagnose this?

Thanks

Sounds to me like the park contact in the wiper motor is bad.

Hey Nate,

Any way to test that?

If it is a GM, just a wild assed guess because of the word '350', then
your wiper motor could be missing a ground path or a power line.

I would hook a booster cable from the battery negative to the case of
the motor to see if that helped.

If not, then the power is being interrupted. If you live in the snow
belt, you could have tried to start the wipers frozen to the
windshield. This will burn out the intermittent module and can take out
the park.

Hey Mike,

Yeah GMC Suburban (burb)

The motor is bolted to the frame by 3 bolts so I don't see how it could be a
ground issue. I will try it though. Better safe than sorry

No I'm down south in Texas. Never seen are "real" snow like back home in
Montreal
