Ford Blower Motor Controller

Question for all of y’all.
Start off with... I have a 2006 F350 Lariat with automatic climate control.
So.... One night I jumped in my truck and started it up and the fan all of the sudden kicked on high. It the off button and it kicked on high but changed the direction to defrost... Turned it back on and tried turning the fan speed all the way down but it still stayed on high... I was able to change the direction and temp but not the speed. And turning it off only changed it to defrost at full blast... Did a little research and this sounds to be a common problem when the Blower Motor Controller fails (old part number 3C34-19E624-AA - new part number 6C3Z-19E624-AA). Local dealer wanted $140 but I found it online for $70 which I thought was still too high. Went to the local wrecking yard and looked at all the Super Duty and Excursions they had and they were all the manual control systems which had a different controller than what I had. So I hit up my buddy that works at a different yard in town (they only have imports on their lot) as he has connections with yards all over the state. He was able to have another yard find out of an expedition that looks to be the same but the first part of the part number is 3L1H rather than 3C3H. Part looked to be the same exact thing so we plugged it in and it seemed to work just fine (for the 30 seconds I had to play with it as I'm in the process of painting my house). So today I did a Google search of the middle number of the part (19E624) and multiple Ford models came up so I'm wondering if they're interchangeable??? Pulled the covers off both parts and they both look to have the same internals and layout. But.... the transistor on the outside that's surrounded by the heat sink has a slightly different number but noting comes up when I search it. So the first number on the resistor is MJ11028 which when I Google stuff comes up but 2 lines it has a number or BM0511 (on my part) and BM0335 (on the part my buddy found me). When I search those "BM" number I get nothing.
Any electronic people or Techs out there that might know the difference?

Talking to an IT guy at work it could possibly be an internal manufacture batch number and that's why I can't find anything on it. Still puzzling why the first part of the part number is different.

This coming from the guy that bought the updated STC fitting when he studed his truck but then turned around and returned the STC fitting because he thought it would be to hard to change it out... And now the old fitting failed and left you standard an possibly toasted your hpop.

I just want to see what others think. Not sure if I like Eli's thinking of if it works don't worry about it. Look where it left him...

I have a new saying after all the stuff you've gone through. "Don't pull an Eli".

Wow... run on paragraph there... sheesh.

Those look like the date codes for manufacturing.

First one probably 11th week of '05. Second one, 35th week of '03.
