2022 Toyota RAV4 — blower works on some speeds but not others

I wouldn't throw parts yet. Get a real battery/charging test on the 2022 Toyota RAV4, not just resting voltage, before blaming a module. If the cheap test changes it, stop and reassess. Had a similar mess a couple years ago and that's what finally sorted it. Your commute and mine probably aren't the same, but the test still applies. This is me being the wet blanket on purpose.

This is usually cheaper to test than to guess. Swap the cheap/easy piece first on the 2022 Toyota RAV4 and see if the fault moves. You'll know quickly if you're on the wrong tree. Happy to compare notes if your setup is different. Trying not to diagnose from the couch.

Log the conditions before you spend. Get a real battery/charging test on the 2022 Toyota RAV4, not just resting voltage, before blaming a module. You'll know quickly if you're on the wrong tree. On “blower works on some speeds but not,” that was the fork that mattered for me. Keep sale price, fees, and rate as three different conversations. No warning lights, which is why I'm documenting it.

Ask what changed right before it started. Move a coil or plug on the 2022 Toyota RAV4 if it's cylinder-specific and see whether the code follows. If the cheap test changes it, stop and reassess. A shop burned me once by skipping that step. A day of patience here is cheaper than a wrong part. I'll update if anything new shows up.
