Fuse or something else?

[HyperYellow]

My HVAC, front and rear screens stopped working today for no apparent reason.

I pulled the plastic trim panels off so I could look at the wiring. The rear screens power wire (yellow) taps into what looks like an orange with purple stripe wire that goes into the side of the factory stereo.

I suspected this wire was not getting any power so I ran 12v to it and everything worked again.

Does anyone know what fuse this is because I have checked dozens of them, or could it be something else?

If it helps, it is pin B10 on the 40 pin connector that is not getting any power.

I need help with this badly. I ran a new 12v source to it with a 30 amp fuse and it keeps blowing. What is going on???

Check to make sure wires aint touching, either wires touching or you have a bad earth

Well I found out it was the wiring for the rear DVD screens shorting out somewhere. I cut them off and the air con and all that is now fine.

I am going to rewire the DVD screens and see how that goes.

Still wondering if there is a factory fuse for the hvac/front screen?
