Bulb replacement rear armrest

Does anyone know how to get to the bulb in the rear armrest on a '68 convertible? The assembly manual wasn't any help. Thanks, Mike.

You need to remove the lens by depressing the tabs on the top/bottom and pry the lens out. Then it's the same method as removing a typical bayonet type bulb.

Be gentle as the plastic lens gets very brittle with age and can crack easily. I use a very thin flat blade screwdriver to depress the tabs.

Heres a pic of a 68 rear armrest lens to show you the tabs that hold it in:

Yes.

Pry off the lens and replace the bulb by twisting it 90° counterclockwise and pulling it out.

The lens is held in place by small, outward-facing tabs along its horizontal (top and bottom) surfaces. Use a thin object, like a scraper blade, to gently pry one edge inward and upward to pop the lens out.
Be careful, as these lenses are thin, and get brittle over the years, and are easy to crack.

If you do crack it, don't worry, they're available from the aftermarket suppliers, and the same ones were used throughout the GM line for many years.

Also, don't forget to use the correct bulb - an 1157 or similar will just short out your light circuit.

But guess what - like most repro parts, some from some suppliers are ill-fitting. Mine are and hopefully by now they have been improved.

Got the light cover off with no damage, and when I touched the bulb, it came on, so easy fix. Thanks for all the help.

Glad it was that easy!

I'd pick up a few extra #90 bulbs anyway, because now that you fixed it, it'll want to go bad on you again at a bad time.

If touching it made it come on, then the contacts and springs are probably sticking. You may need to remove the bulb and spray some cleaner down on the contacts and work the springs in and out to free them up. Might be best to remove the housing so you can best access the contacts. If they stick, which they did, vibrations may slightly depress a contact spring. Then it sticks and doesn't rebound to keep the connection tight.
