so on my 92 camaro RS the dash warning lights dont work, the check engine light works and the airbag light, but nothing else. i dont know what else there is, as I can't see the dash, but the seatbelt one doesnt for sure. no other warning lights on the dash do. my door lock buttons work half the time, and sometimes when im driving down the road you can hear them click when hitting small bumps. one of my speakers doesnt work anymore.

the speaker and door lock problem came after I had my heater core repaired, could there be a crossed wire? thanks alot
