As crazy as it is mine is doing the exact same thing it kept dying so I had my battery tested and it wasn’t holding a charge so I replaced it . Then yesterday my alternator took a crap it’s being rebuilt currently and once that’s in I’m gonna try to figure it out . My abs doesn’t work anyway so it’s no big deal for me to pull the fuse

my battery tested fine, I’m not sure what’s up

No the drain killed my battery then I replaced battery and alternator was on its last leg. It’ll be in tonight I’ll try to take a look and help you out since it’s the same issue . It’s draining mine enough to kill a battery overnight

I’ve read up and it could be the relay? Or the blower motor? Not sure how to test it, but once again it’s too cold for me to keep working, so a problem for tommorow!

Maybe try swapping relays , I know the blower motor resistor causing issues but I’ve never had one go bad but I know it’s oretty straight forward to fix if that ends up being it

also is fairly expansive if it’s not it 😬

I think you can test it with a multimeter. I’m hoping someone who knows more about this can chime in

so far I tested the fuse, so it’s not that, hoping to get some time to test the relay, and if that’s okay... just pray for me it’s not too expensive 😂
