Okay guys.. HELP ME OUT HERE. Today while I was gone my grandpa (me and him work on the car together) decided that he was going to figure out my cooling problem.. Well he did. Appearantly it was a broken heater control valve.. So he ripped it out completely and put it aside.. O_O. Ever since he did that lots of things stopped working, my horn, my button door unlocks/locks, my dome lights, etc. The headlights and dash lights still work however. WTF Happened. I was pissed, but idk what he did exactly, OH, and their is a hissing.. almost like a vacuum hissing problem that i can hear on the inside of the car.

What should I do? Will re-installing a new "heater control valve" fix these things..? Lemme know, thanks guys.

 

Soo.. Nobody knows what the problem is?

 

Checked your fuses? First thing my mind jumped to.
