i have a '92 hatch and i recently tried to install a radio when i must've mistakenly crossed a + and a - wire together. the raido blew and i have since taken it out. now i'm having some electrical problems. for example.. when the car is off the lights on my climate control stay on and so does the blower (if i dont turn them off)...when my headlights are on, the dash doesnt come on all the time (sometimes it does if i hit it), and when i open and close the sunroof i keep blowing the sunroof fuse.

can this be due to the main relay going bad? please help, any/all suggestions appreciated.
