I've been noticing that lately one of my headlamps is getting tired, sometimes it wont rise for 15 seconds after the other one. Should I just clean up all the contacts, or is it a sign that I might be needing to replace the motor? I'm really wanting to change out the instrument color, since I've had the kit for about 6 months now. Also wanting to install the electric antenea. Since I'm not working, might be a good time to tear apart the dash again..?
