Stumper! Help needed!

[Gsxr150]

Hey guys,

I have a weird one happening! I have a new (2019). Before last night I didn't notice this issue... Around 7 last night I prewarmed the cabin so I could clean it etc. After I was done I noticed a light humming noise coming from the center of the frunk, at about the windshield. Figured it was a "Tesla thing" and let it sit overnight. However this morning it was still happening. So, I plugged it in for a bit, then took it for a drive to try to reset it. Sure enough, it was still humming when I parked it (very light humm). I tried locking, unlocking, letting it sit for a couple more hours, turning on cabin temp, turning off cabin temp, and everything in between. It's still doing it...

Here's the kicker...something even more odd. I let it sit for a while longer, and when I came back out I could feel air rushing out of the passenger window, like the blower turned on! The car was powered off and locked! I'm totally stumped. My garage is about 55 degrees and nothing should be on...

One more note (symptom): Oddly enough when I open the door and the screen comes on it stops. It sounds like it's the HVAC motor running...but pushes no air when I close the door. When I come back an hour later you can feel wind coming out of the passenger window. Is it becuase I have one window open a crack?

Thoughts?

If it's a light wind noise while parked, people say it's the car keeping ventilation through the AC unit to dry it off. I know - it's plenty dry in Minnesota in the winter.

If it's a loud noise like a jet engine, then it's something else and not drying the AC. Mine does that sometimes, then it stops completely when I open and shut the door. It doesn't take a drive to make it make the noise - a few weeks ago I backed the car out of the garage, moved something then put the car back. The roar came on and didn't stop until (eventually) I opened and shut the door. Dunno why it does that.

I'll let her sit through and day and night and check again tomorrow AM...

Any water under the car from the AC condensate?

I'll check!

Was it an electrical hum, a fan hum or a pumping hum?

Almost sounded like an electronic hum. Until I went back out and the hvac was running. I think it may have shut off! I'll keep you guys posted.

Ours does that sometime. Open the door it quits. No rhyme or reason to when. I ignore it. I'm not noticing any vampire drain. Meh.

Me too! This is my second Tezzla...no I'm not a rookie, but thought it was odd. PS- had a Model X. It was fun, but this thing is zippy. I'm in love!

The car often makes noises. It would be interesting if someone made a little guide to the different sounds.

For example, open the door, there's a clunk-clunk and then fan noise, IIRC. What's it doing?

Haha no kidding right!!

clunk clunk sounds like contactors

 

[bbell]

The clunk clunk is the high voltage contactor closing connecting the big battery, before that the car is using the 12V battery in the frunk.

Fan noise? It's there to mask the pumping sound of coolant moving thru your battery pack. If you heard that, you'd freak out more!
