'98 Stratus issues

Sorry for the lag in response.
If you use a donor, make sure the P/N's match or supersede one to the other. Either forward or backwards. the P/N should be on a decal on the PCM.
If a donor will work, a flash shouldn't be a problem. You will know very quickly. The PCM won't communicate to the scan tool to preform the flash. If you get communication, you're likely golden.
and by the way, I would have told you to replace the resistor too. That is the usual suspect on 99% of chryslers with no blower motor. But I have seen the pigtails burnt or broken.

Thanks, gunbunny. The info I'm finding on here is great on this.

As for the blower motor resistor it wasn't on a Mopar, it was on a Honda and gave more of a GM response in testing. Resistor good, pigtail giving various readings from the same pin. I told the woman GM must have made her Honda. There's a reason the new GM resistors come with a new pigtail. A little contact cleaner, a little dielectric grease, plug in firmly, and her system went to working again. And still is.

But that's the reason we do the full testing isn't it? Don't assume because we've replaced a 100 of 'em that number 1o1 is the exact same thing. TSBs can be handy diag tools and a common fix for a common problem, but I've seen guys rely only on the TSB and wind up not fixing the issue...then wonder why it didn't work.
