i dont know who i pissed off above, but just when we get 2ft of snow and cold temps...BAM! overnight:

keep in mind this is for a B5 Audi A4, very similar electrical system:

What doesnt work:

-no heat, the blower isnt working. but the console is.
-no turn signals, but parking lights work
-no fogs
-no boost gauge lighting (directly wired to 75x)
-no wipers

At first i thought maybe the nut came off the 75X post, no luck, i dropped the knee bolster at lunch, everything is secure. Also I checked every fuse 25Amp and greater, even the 40 and 50 under the relays. all are ok.

What works:

-HEATED seats, thank god.
-interior lights
-stereo works
-hi and lows beams

i plan on checking the ECU box, is there a relay for the switched power (75x)?

THANK YOU FOR YOUR HELP! :thumbup:

ignition switch, had the same exact problem
if you had a volt meter on your car you would also notice a low reading at startup and until you reved the engin/started driving.
