The Stovebolt Site Forums The Shop Area General Truck Talk Wiper motor hole and motor 46 COE

I have two holes for a wiper motor on the drivers side. I'm not sure what one I should be using. I'm also not sure if the motor I have is original.

See Page 2. http://rides.webshots.com/album/579922456jFVpcI

Was a passenger side wiper an option? I welded the hole up because I didn't have a motor for that side. There was a total of 4 holes for wipers motors, two on passenger 2 on drivers.

Thanks,

I think if the motor were original, it would be a Trico vaccuum operated unit. I believe the passenger side was an option.

Im betting the hole that is supposed to be used on your truck is the one on the right side of your pic. I think its about 14" from the divider strip in the windshield.

Did you ever get my email involving GMC COE part numbers?

It has trico stamped on it so must be the original. Thanks for the measurements. I got your email on the part numbers.

Thanks,

I had my driver side wiper rebuilt by Wiperman. It has two controls. One pulls in/out the other turns. I think the turning one is supposed to adjust the speed, but I see little or no effect from it. Pulling the in/out lever part way does give a slower speed.
