2016 Yukon SLE Front Wipers will not work.

[justjohn4]

Hello,
My wife's wipers stopped working after the wind shield was frozen over with ice for a few days.
I have replaced the motor not thinking much of it but when that didn't work I checked all fuses.

I noticed the relays seem to be integrated and nonsurvivable relays. No other issues at all.

You can hear the relays click when the wiper controls are engaged and the BCM is commanding the wipers to come one but still nothing.

Is it possible I received another bad motor from the parts house or I have been told its likely one of the integrated relays and I need to change the fuse block.

I hope that you will become a participating member in the Forum's discussions.

Pics of the truck, please.

I cannot personally assist you with your issue, but other members of this Forum much more knowledgeable than me in this area will chime in.

If you have a volt meter, you could check to see if you are getting 12 volts to the wire harness connector that connects to the motor connector, when the wipers are turned on.

Thanks Joseph,
I do have a meter and can meter the connector easily. I just dont have access to what pins are voltage and what pins are ground as I have 12v to chassis ground at the motor.
Im just not sure if the relay it producing voltage or the ground to activate the motor.
