I did a search and found nothing on this (so maybe I used the wrong search criteria, no doubt), but I thought I could use someone's two cents on this. Twice today within seconds of starting up my MM I heard an odd thump, and as my memory tends to be unreliable, I believe I've heard it before, and it only has been happening since doing the EATC fix with those silicone o-rings I bought from McMaster-Carr (or so it seems). Could the o-rings possibly be binding in the solenoids? I'm wondering if maybe it's because I usually don't turn the heat or A/C off before shutting off the car, as well. I'm not lazy, just never think about it before getting out of the car. Never have, even with my old Lincoln. Anyone else had this issue?
