Default radio/cig lighter only work with ac on?

like stated in the title. the radio and cig lighter only work when the ac is on, and they cut out when the ac slows down going up hills.

my radio fuse is fine, its also tied in with my headlights awkwardly(headlights currently work whenever)

also when testing the power output depending on ignition position, if the ignition is one click before ignition, the ac blower turns on, but the radio/cig lighter do not.

im leaning towards the ignition switch but not sure that is actually it. i couldnt find anything else online as to what it may be. what do you guys think?

WOW! I wish I could help you with this one but it sound like you have a major electrical problem. I do hope that someone on here can be more help then I can.

im praying for a miracle, that one day all wiring gremlins will magically vanish.

update

i just checked a few things out. with the ac on and the radio turned off, the lighter will still push power out.

Well after a long night of tearing it apart, the problem was that the guy who installed my stereo tapped into the wrong wires and melted them after time.
