What do I need to sell my car in Ohio?

I just bought a GMC truck. While I discussed the powertrain warranty with the salesperson prior to the purchase, I want to learn a little bit more about it in case something goes wrong. What’s the powertrain warranty from GMC cover?

I’m trying to get my car started for my morning commute but my car has trouble starting in freezing temperatures as it’s an older vehicle. Starter fluid usually does the trick, but I’ve run out. I’ve heard that you can use brake cleaner as a starter fluid substitute—is this true?

I pulled into my driveway yesterday, but when I hit my garage door opener, nothing happened. I had to get out of my car and put in the code to get it to open, which was less than ideal since rain was coming down in buckets. How can I reset my garage door opener?
