Took it out & upon examination found that the culprit terminals needed exactly that. Resoldered the unit. No help. So I bit the bullet & bought a new RCM. No help, plus I couldn't get the shifter out of Park. Whaaat???

Just for laughs I swapped the old RCM back in, figuring that with it I at least could get the car in Neutral. The damn thing fired right up. Whaaat??? Worked fine for a while. Then, no crank.

Swapped the new RCM back in. No crank, but the spoiler deployed. Plus, I couldn't get it out of Park (again). Put the spoiler back down & it fired right up. Whaaaat??? Shut it of & re-started it several times. No problem. Drove it around for a little bit. No problem. Shut it off & re-started it several times. No problem. Spoiler worked fine, except I didn't go fast enough for the auto-deploy to engage.

I'm really stumped here. I 'm glad it starts & runs, but I'm leery of taking it anywhere for fear of it taking a dump on me again.

The only thing I can guess is that there may be a loose wire somewhere in the harness or something else stupid.

Any thoughts/input/advice? TIA
