Default Re: A/C blower fan won?t turn off

I've been fighting this same problem for a few months.
Recently I noticed my wiring harness is the same as yours pictured Starman with 3&1 contacts as opposed to the 4 & 2 contacts on the BCM.
I have a Jeep unit ordered and am crossing my fingers that it works.

Did the jeep module fit your car and work? Same problem on my car today?

Thanks.

I purchased mine through eBay. This was the link. The unit worked fine but it did need minor modification. I had to swap my cooling fins on the OE part with the replacement. The replacement fins were too large to fit the opening. The plugs matched up perfectly and it has not been a problem since. If you do this swap, be sure to try and retain as much of the adhesive. It is also a heat dissipative as I understand it. https://www.ebay.com/itm/15580780457...mis&media=COPY

It was a relatively easy swap.

I purchased the Jeep module off of Amazon and it works. Mine fit with no modifications. The holes didn't line up exactly, but that's not a big deal.

Here's the title:
