Works as suggested.
Productive and really, really good condition. Plastic housing makes it easy more weather resistant. Just do not tighten it too much or you will break the plastic.

As advertised but wrong part.
This is just as ordered. Unfortunately, the part listed in the diagram was not the right part. The one that came was the one ordered, it just wasn’t the right part.

Blowing fuses...
2010 Town and Country blowing fuses for the power seats, and this is money well spent. I had to rig it up on the firewall, cut a few notches in the fuse box had to put a couple terminal ends on it to fit it on to the fuse terminals, sealed it with some silicone , but no problems since.
