Has anyone replaced the wiper relay/module in a Silverado or Sierra before? I am looking at the wire diagram in my manuals but there is nothing on the actual location. The places I have looked that are labeled on the diagram are no where near large enough to house the new module. I was thinking under the dash or under the hood near the wiper motor. Nothing popped out at me in those places unless I have the wrong replacement part, which could be possible.

I found it and now I know why I was thinking the new module would not fit in the casing. It won't. Even though everything I have found for a new module says that it is for an 88-99 the module in my truck is a small rectangular board and the new modules are in a U shape.
