Does anyone have an idea on why "All of the sudden" my reverse lights, radio, and turn signal stopped working? I recently installed an A/C kit from Classic Auto Air which went in very easy. It was a very simple install without any problems... All I'm trying to figure out is, why that particular circuit died... I retraced my steps over & over & over... NOTHING! I check the fuses and the wiring, even at the firewall.
I bypassed the turn signal switch directly to run off the hazard circuit (which works fine), but it's not the right way and I don't like it!
Is there a "Series Circuit" that controls the heater box? I'm completely at a loss.... Please help!!!

Thanks!
