please help me out, those who may know what problem my car is having at the moment.

how it started... my radio/clock/ac display blacked out. searched the net and said that all i need to do was disconnect my ground. i did it and wha-la it came on.

now the problem... my ac is not blowing cold, it says 15 degrees on the display, wipers arent working, parking brake light is on even when the e-brake is down, alarm is not responing to remote, my hazard and signals are not responding as well.

sigh. please help
thank you
