I'm lost please help
 

I've lost turn signals, windshield wipers, radio and heater on my 2000 audi a6t. i replaced the ignition switch and a couple relay's and i really can't afford to take it in to the shop again. All 4 went out at the same time also.

first step with electrical issues - find the fuse panel and start there
also more details with what exactly went out with all those, ie, heater isnt blowing any air or it isnt hot anymore, ect.
