    C2 Headlamp Actuator Issue

    Edited to correct original title to "C3..."

    I've not seen this specifically addressed previously, so plz excuse me if I've overlooked it. Although both headlamps operate, they are very slow (up and down). Neither actuator will hold a Mighty Mite vacuum for more than a few seconds (2 sec vs 10 sec).

    Most previous posts pointed to faulty actuator shaft seals, so I ordered a couple from Paragon (before removing the old ones). The seal on the actuator with the fastest leak actually looked in good shape. I connected the Mighty Mite to the backside of the actuator (opposite the rod and seal) and found that leak appears to be from that side. Indicates to me there is a defective "diaphram" inside the actuator because the rod seal is now out of the equation.

    Have any of you had similar issues and found a solution? Obviously the "canisters" are sealed and the diaphrams unservicable. Don't hurt yourself laughing, but I wonder if something like liquid tire sealant might help. Other suggestions?

    I'm not looking forward to buying replacement actuators. Haven't seen any that appear to be close in appearance.Also, the Paragon seals are about 1/8" shorter than the original, and the small end is slightly different in construction. Has anyone used Paragon seals successfully?

    Thanks,
    Mike

        Mike, I would think you may have some luck searching your local craigs list for a use actuator, seems that there are quite a few 70's parts cars about. or maybe Ebay may have a NOS one.

        There are no quick fixes for those things if you have already put the seals in.
