2015 WRX: HU, Interior Lights, Keyless Entry Failure

Featured Replies

I've combed the web and posted this on NASIOC already, but I can't seem to find a solution. Hoping there are some ideas here. It's been awhile since I've visited. 

I have a 2015 WRX. My tire inflator blew a fuse, which has happened several times before and typically I just replace the fuse and go about my business. However, this time my HU, trunk light, interior lights, and keyless entry have stopped working. The interior power door lock switches work just fine and the car alarm is set off when I unlock the car with a key, but the car doesn't beep when you lock it and then close the door. The keyless entry and trunk light are on fuse 15. I've checked all of the other fuses and everything looks in good order. I've checked relays. I've tried disconnecting the car battery and still no luck. 
I've seen other posts that point to the "back-up" fuse as being the problem. To clarify, that doesn't seem to be my problem. The fuse is good. There has to be something that I missing. 

 

 

Fuse No. 15 is powered by Fuse No. 8 and is 20 AMP.

Check #8.

Thanks. It has a 7.5 A in it as stock. Nevertheless, I tried it both ways and that didn't solve my problem. 

Fuse 15 should be 10 AMP according to the Wiring diagram.

Fuse 16 is 7.5 AMP.

It looks like Fuse No. 8 is in the fuse block under the hood.

Ah, the exterior fuse box. Fuse #8 was missing. So I put a 10 Amp in and everything came back to life. Thank you....so what happened to the fuse that was there?

Someone playing games, or a ghost in the machine?

Glad it works.

The wiring diagram calls for a 20 AMP fuse, so that is what you should put in.

Thank you. I will make that change. I owe you one!
