Both headlights suddenly pointing down!

[bumbazs]

Hello, yesterday everything was fine, today while driving home, noticed that my headlights pointing really, really low, can't adjust them from MCU, they wont react at all. Can both headlights motor suddenly go bad, and both drop to lowest possible position? TMS 2014..

In service menu there is nothing releated to headlights, only noticed that every 5 seconds there is THC errors, maybe its somehow connecting..?

Waiting for your thoughts, thank you!

These errors are the front vent doors and the Thermal system heater (including Battery heater), and the inside heater. Mostly sensor and timing "temporary" errors, unless the heat stops working in the cabin or you get the PTCTempRange more than occasionally. You can check the two front vent doors to make sure they are opening and closing normally. Unless there are electrical issues in general in the front, these errors would not normally affect the headlight adjusters.

Ground problem?

It could be releated to ground, possibly. Because i have another issue, when there is raining outside, tens of errors hits, and car is undrivable till its dries out.. ground studs under frunk is checked and good, can’t find the root of the problem. Thanks god, sunny days came, and car not dying, but seems other issues like this is popping up now….

bumbazs, what model Tesla is this? Your post is in the Model S section and I've never seen those headlights before on a Model S.

Yesterday i noticed, that the headlights during daytime, was back to normal, at night they again falled down! What is happening? tried to shine the flaslight to sensor, no changes.. Maybe there is really somewhere bad ground, and at night when there is more moisture outside ground is acting crazy.. I don't know.. Ground studs under frunk is cleaned, retightened..
