the BCM supplies a ground to the control side of relays (#85) we need to see if BCM is in control or relays.
SO with KOEO wipers selected lets look at HI speed to start, is 85 a ground?
then select different speeds for a quick confirmation..

This was a NEW wiper motor?
If not we may have to validate the part as good on vehicle.

When I see the price of OEM I think aftermarket.

85 shows 12 volts in high and low positions.

87 ground.
87A groundin high position, but not low.

The wiper motor in new. I have a pigtail and can run it one speed and works just like my old one
now I have a spare.lol.


MFS....KOEO
#7 showed 5.9 volts, is this residual voltage?
#8 0 volts.

I have voltage on both # 85 positions, is it possible I'm not looking at the diagram correctly as you have said # 85 should be a ground. I got a feeling that I'm the one making a mistake on the numbering. I will see if I can post a drawing on the forum. Thanks again for all of your help. Below is what I have so far, not professional but hopefully will show what I have and where.

Thanks again for all of your help.

#85 should be a ground. This is how the BCM energizes the relay.The BCM grounds this wire.
#86 should be 12v, this and above (#85) are the control side of relay.

When the BCM grounds #85 the relay closes and 12v is then present on #87.

Two questions.
1. Do I have the numbers correct as is 85 shown were I have it in the drawing?


2. Could the BCM cause this issue? (everything else works except the front wipers)


Thank you.

The attached PDC pin out should help ID which cavity is what #.

I want to ask again - you did remove the IOD fuse count to 10 then replace it?
Thats my secret BCM reset hail mary.

I checked the IOD once again and let it reset. All fuses have removed and checked separately. I have remove and switched around relays. There is a light blue wire that I notice was taped off and not attached. It looks to comes out of the main harness that goes through the firewall. Any idea what this goes to? It is a factory wire as I can see it intertwined in the harness from firewall. It looks like it has been pulled out if the back of the fuse block.
