2021 Tesla Model S — blower works on some speeds but not others

Ask what changed right before it started. Write temp, speed, and in-gear vs coast when the 2021 Tesla Model S does it — then decide on parts. That's the branch I'd chase this week. Verbal 'we'll take care of it' is not a plan. That's coming from doing this as an owner, not a shop. No warning lights, which is why I'm documenting it.

Intermittent stuff lies if you only catch it once. A pressure test beats staring at a dry driveway if the 2021 Tesla Model S is losing coolant with no puddle. That's the branch I'd chase this week. On “blower works on some speeds but not,” that was the fork that mattered for me. Happy to compare notes if your setup is different. I'd rather look cautious in this thread than stuck later.

Start with the test that can prove you wrong. Loaded-suspension checks on the 2021 Tesla Model S catch play that a wheels-hanging inspection misses. Don't erase codes until someone who can help has seen them. Post the numbers (or the code) and people can get more specific. Next check is the cheap one I can do in a driveway.

If it were in my driveway, swap the cheap/easy piece first on the 2021 Tesla Model S and see if the fault moves. That's the branch I'd chase this week. This is from a 2021 Tesla Model S in Charlotte with 35,000 miles. Do that first. I refuse to clear codes until someone else sees them.
