Turn Signal Problem

[RLS40]

Hey gang, first timer here. We have a low-mileage 2004 S40 and like the car. However, we recently had a problem with the turn signals not working. Turns out the fuse keeps blowing. I've gotten things opened up and i see continuity (short) between ground the load side of the fuse socket (no fuse in it obviously). I unplugged everything from the turn signal stalk and I'm still seeing that short and the fuse is still blowing. I don't know if this is important, but on the plug that I think is for the turn signals, I see continuity between ground on the brown and brown/black wires...and now the green/yellow. Any suggestions on what do from here?

TYIA!

The fuse that's blowing is 11 B/6 coming off the IG2+. The continuity on the two brown wires makes sense, because they appear to go to the bulbs. What I can't sort out is why am I seeing ground on the load side of the 11 B/6 fuse socket and what that might mean for tracing this further.

I found an aftermarket towing light adapter scotch-locked into the rear end of my 00 V40. Removing it made it stop blowing fuses.

I found this thread because my 2004 Volvo V40 is also having the same issue. it's the same model as yours but the wagon version. I haven't tested any continuity but it's also the 11 B/6 off IG2+ fuse that keeps blowing for me too. I also get a burning electrical smell sometimes after replacing the fuse and switching the key to just the on position sometimes blows the fuse. Did you ever figure out what was the problem?

Wanted to post an update and I think I may have found the wire that is causing the issue. The 11B/6 Fuse is connected directly to the Hazard warning flasher switch. I removed the hazard warning button from the dashboard and got the connector pins exposed. I attached black lead of the multimeter (in continuity mode) to a chassis ground and the red lead to the pin that corresponds to the yellow wire
Should be the third one from the left, bottom row of the connector.
It read 0.00 when it should have no continuity to ground. I also ran another test and used a test light with the key switched to "ON", ground lead to the power side of the 11b/6 fuse and the probe with the light to the Yellow wire pin in the hazard switch. The light went off so there's a short to ground somewhere on this wire. That's as far as I've dug, will try to trace the wiring harness though it seems like a decent amount of dashboard disassembly will be required.

I believe the fuse box is the problem. I removed the connector for 11/2_C:12 and there's still continuity with ground on that pin on the fusebox side. I've already ordered a replacement passenger fuse box and will update if it worked once it's installed
