For the headlights, before you go spending lots of money on rebuilt motors, there are two common problems that you can fix yourself. The first is the bellcrank. That is the arm that the motor turns that opens the headlights (see first photo). The bellcrank is made out of magnesium, which is quite soft and so the output shaft of the motor, which is hardened steel wollers out the keyway on the bellcrank over time. Mine had the same problem when I bought it. The 2nd thing it could be are the 3 circular rollers inside the motor gearbox (photo 2). The original ones deteriorate and crumble. Mine were ok but I replaced them anyway. There is a guy over on the aaca forum named Barney Eaton that sells a kit to fix both problems for $45 per side. Comes with detailed installation instructions as well. His contact info and parts catalog are pics 3 and 4. Hope this helps.
