Alternator dying?

[2017azlaramie]

Hello,
I have a Ram 1500 Laramie hemi 2wd. A week ago my ac blower motor started working intermently. I had the battery checked (it was 3 1/2 yrs old). And turned out it was bad. I replaced it this past saturday. And things worked great until yesterday (tuesday) afternoon. Also my radio screen is taking sometimes 5-10 mins to come up. I'm thinking alternator now.
Anyone had a simalar issue?
Did you have any luck with alternator testing at Oreilly/autozone? (It's all there is near me) Not buying alternator there.
Does replacement of the alternator as simple as it looks?

Thanks in advance.

Update, volt meter on battery is reading 13 volts engine off. 14.5 volts engine running. And blower motor is not running again.

Check all the fuses in the fuse box. They can self-lift ...in some cases. How's the truck's battery-to-body ground wire?

sounds like your charging system is fine as for the blower motor need to check relay under hood the relay pin terminals have been known to burn up and loose connection mine did had to replace a terminal in the in the relay socket.
