I have a 1987 t/a. When the key is off and I push the brake, the seat belt chime goes off as long as it is pushed. When the key is on I don't have this problem. I have tried bypassing the brake switch, and I also replaced the turn signal harness but that was because of another problem. I've replaced all the bulbs also. I also have a problem with the right turn signal blinking fast when the head lights are off but when the head lights are on it doesnt work at all. any ideas from anyone please?
