I have a 2015 Toyota Corolla le with an automatic transmission that I bought in Sept 2016 from my a dealership my dad used to work for. Jerry's Auto/RV Sales in Lennox, SD. (He stopped working there due to them not giving him the right commissions for sales he made there and probably more reasons.)

Currently my car has 99,477 miles on it and when I bought it, it had around 42k miles on it. Anyway, I noticed that when I'm in idle in drive, ex. At a drive-thru, my car will sometimes vibrate a bit and make an odd, wet type sound? Sorry its hard to describe 😅  and the other day the air vents weren't blowing heat/ac, or air period. Now come today, the air is working but I don't want to rely on hoping they will work because I live in the midwest & winter is going to show its ugly face any second. Lol. My dad & his dad have been in the car business forever, but there are some things my dad isn't totally knowledgeable on. Thanks in advance for all the helpful tips/advice you guys share on here.
