FRM's are fragile, but used ones are pretty cheap. I had a bad junk yard one (got my money back), one that lasted less than a year before dying and my current that is on a couple years now and doing just fine.

$500 for a new one or under $50 for a used one. Not that hard to swap. Same as my HVAC controller; I had to buy 4 before I found a good one, but under $50 and got my money back on the used ones (and sold all the bad used ones, listed as being bad, for about what I paid for my good one). 2 minute swap, so not a big deal there.

That said, none of those listed symptoms were what my car had with bad FRM's. It was always lighting related.
