My instrument cluster went blank after the installer connected my Blackvue 900X-2ch in my 2013 Model S (out of warranty).
Short version: Tesla replaced IC fuse and disconnected the wires to the camera. I don't think the camera connection caused the fuse to blow.
Long version: After the installer finished, the dashcam worked fine but the instrument cluster was blank. I added the non-working IC to my existing service appointment, and approved the $180 diagnostic fee.
I brought it to Tesla. I disconnected the wires from the front and rear cameras as I always do when I bring the car for service. If I don't disconnect them, service does.
Diagnosis was blown fuse, and they said they would replace it no charge (other than the diagnosis fee). I approved the work. Got the car back and they had also disconnected the wires the installer had connected.
I do not believe the camera caused the fuse to blow for the following reasons.
1. The dashcam worked fine after the install. It has 3 wires - 12v always on, 12v switched, and ground. Camera recognizes when car is turned on, and continues to operate when it is turned off. This leads me to believe both the switched and unswitched power is working, as well as the ground. If the dashcam blew a fuse, how would it work?
2. I believe the technician made an assumption the dashcam blew the fuse. I did include the information that the IC went out when the camera was installed. How could he know what caused it to blow?
3. I see no way having the wires connected to the car, but the plug to the dashcam removed, causing any problem. Now that the wires are disconnected, I even verified there is no continuity between any of the 3 wires. Besides, the camera worked even through the IC was out - so I don't think the wires were shorted.
I guess it is possible the dashcam is somehow causing the IC fuse to blow, yet is not affecting the power to the camera - just seems unlikely to me. Has anyone seen this before? I think it is more likely the installer blew the fuse while testing the power locations he was going to use or when connecting the wires - not when the dashcam was turned on.
Where am I going wrong?
