Mechanic said ive got "some kind of electrical issue". Sent my RCM to tighe, but him resoldering didnt fix the issue and i trust his work. So i am ordering one. It was suggested that i try an RCM from a working crossfire and see of my car starts...i have access to one, same year and everything, just the bad *** package...anyway my question is, if its not the RCM and i put a working RCM in my car, will whatever issue i have RUIN or blow up their RCM (lets assume my issue ISNT the RCM, but im sure it is cuz he tried it in his crossfire and it didnt work after he resoldered)? Think there is any miniscule chance of ruining theirs at all?
