2024 Kia EV9 — blower works on some speeds but not others

CleanBuyer879Community StarterMay 4, 20262024 Kia EV9 GT-LineBoston

Cabin fan works normally on certain settings and then cuts out or changes speed unpredictably on others. Before replacing the blower motor, what should be checked in the resistor/controller circuit?

I'd want a measurement, not a hunch. Loaded-suspension checks on the 2024 Kia EV9 catch play that a wheels-hanging inspection misses. You'll know quickly if you're on the wrong tree. This is from a 2024 Kia EV9 in Boston. That's the whole play. Heat soak after errands is the other window.

This is usually cheaper to test than to guess. Get a real battery/charging test on the 2024 Kia EV9, not just resting voltage, before blaming a module. Don't erase codes until someone who can help has seen them. No need to make it theatrical. That's coming from doing this as an owner, not a shop. I'll poke at it this weekend.
