Windshield Wipers and A/C Not Working
 

I recently installed 2 subwoofers in my 13 z, and now my a/c and windshield wipers don't work. Air comes out but doesn't get cold. Water for wipers comes out but wipers don't move. Checked fuses and they are fine. All of my connections are connected. Any ideas why this could be and how to fix it? Both were working fine before install.

My guess is that you knocked a connector loose or broke a wire during the stereo install. Wiring diagrams, harness routing, etc are in the FSM (link in my sig).
