been trying to figure out why both my heat and defroster don't work. horn is also broke but that much just be the horns themselves as those have broke on all m bodys we've had. checked the fuses and saw that several were missing. put new ones in and they just fell out. i can't seem to find my repair manual so i'm asking yall what does each of these fuses do and will they fix my issues? i know that the HVAC system has a vaccum problem on many of these cars so i might have to check that. car...
what fuse is what and are any of the missing ones important?
