I have an 05 ford focus zx5. I recently just replaced my wiring harness because it got fried some how they told me. My highbeams flash randomly, when this happens also my radio will jump in volume to high back down to what i had it at, also my car dies, loses all power to everything in it why all this is going on. mainly happens when i use radio and a/c at the same time... CAN ANYONE HELP!??!?!??!!!? even just an idea on what i might want to start working on to ease what is going on atleast. Thank you for your time.
