Ok guys I have a 2006 mercury milan, we had a -54° a couple weeks ago and ever since then my car has been acting crazy! Sometimes it’ll start right up other times it takes four times sometimes it needs a jump. I took it to auto zone and they said everything passed as far as my alt starter and battery… What the heck could it be? It’s driving me crazy
If it’s having a hard time cranking, clean battery terminals. Clean starter terminals and clean ground cable (the other end of the cable that goes to your negative battery terminal).
