Tesla Model X PTC failure

service.tesla.com has the manuals for free.

Yes, I know, that's why I asked how it can be done differently than Tesla. As I mentioned, Tesla has a method for this, which, by the way, I just found in the user manual.

Why do it differently then? Each step has a purpose.

I removed 12v battery and HV rescue loop as seen on video.

Thanks a lot! Is it really enough to disconnect the 12v battery and HV rescue loop so that you can work safely on the car?

Have you seen what the manual looks like and how Tesla does it? Besides, I'm not an electrician to deal with such things. I just want to replace the ptc heater and that 40 amp fuse.

Yes, and I've read the power off procedure. It is only 11 steps including things like putting the windows down, order of operations, and wait times. Nothing difficult.

Have you read about vehicle electrical isolation procedure?

Ah, my mistake. You mentioned pulling the 12V battery and I had recently dealt with HV and LV power deactivation.
The front PTC heater instructions call out "High Voltage Awareness Care Points" and isolation and are important for safety. You really want to insure the HV is off and that you have proper equipment.

Never mind. Got it fixed by replacing PTC, 40A fuse and re installing software. Here is video also for DC DC Convert Front Junction Box Generation 2 Fuse replacement

Is it mostly the fuse not a failed ptc box

I hit the same issue with my Model X 2016. Took it in for diagnosis, after charging me about $300, the SC came back with another estimate of $1600 for replacing the PTC Heater and Fuse. I'm not sure if I want to go down the DIY route yet, any suggestions for a Seattle area shop that can do this for somewhat lesser price tag? Or any Seattle area Tesla DIY experts who can chip in to help me out here? TIA!
