Sun Visor / Mirror lights - please help

I was trying to change a bulb (passenger side sun-visor mirror light) in my 2006 Wagon, and something "shorted". Now both mirror lights aren't working. And also both heated seats stopped working.

I don't have a test-light nor a volt-meter, so I was trying to check the interior fuses visually. I didn't check all of them, but I checked most of them; including Heated Seats and all that were related to lights. Fuses seem to be OK.

Map lights and dome lights still work.

What could be the problem?

Please help.

Thanks!

I tried flipping the bulb. It is a long skinny cylindrical-like bulb.

Still doesn't explain why the driver side bulb and the heated seats stopped working at the same time.

Are these on the same circuit? (Same fuse?)

Actually to my knowledge only the LED bulbs operate in one direction. But the stock ones work both ways. I'm not 100% on this though.

Either way, I tried reversing the bulb. It still won't come on.

And what bothers me most is that both of my heated seats won't turn on. It's -10C outside with -17C windchill factor.

That's 14F and 1.4F for my American friends.

So I called my mechanic...

He says "Are the power mirrors working?"

I check and they're not. But what do the side mirrors have to do with anything?

He says "Don't ask, it's a Subaru. Check the MIR 7.5 fuse".

So I check and sure enough, it's burned.

I replace the Mirror fuse and magically my power mirrors, sun visor lights, and heated seats are all working again.

Problem solved.
