1970 headlamps in low beam issue

[Joe W.]

Greetings!

I have an electrical problem that I need to address this spring.
With the car running, I turn the headlights on in low beam, they
go up but only the passenger side low beam comes on.

When I depress the high beam switch on the floor,
all of the lights come on. I replaced the headlights last summer,
thinking that was the problem but it didn't fix the problem. So I'm guessing
it's a wiring problem. Any troubleshooting suggestions would be appreciated.

Hopefully in the next couple of weeks,
I can get the car out of storage and can start getting to work on it.

Thanks.

You have a bad LH outside bulb or the wiring to it.

First thing I would do is turn the lights on and stick your hand up there and wiggle the connector on the light. If it goes on then you just have a bad connection on the socket. If that don't work get out the trusty test light. You need power and ground. If you got both of them it's the bulb. The ground is probably good if all 4 go on with the high beams.

Hello,

The strangest thing happened the other day.
After taking the car out for a spin around the block,
the wiper door that opened last summer doesn't now.

The running lights and radio that hasn't worked since I bought the
car now works. Well at least intermittently. The radio lights up and the
running lights are both on and the high beams also work.

However, there seems to be quite a bit of vibration in the front and
I'm assuming it's loosing up some connection. The front end years ago
bumped something and did some light damage at the nose and busted off a
piece of the left lower turn signal frame, but no other damage was visible
from underneath.

I wonder if after having it on jack stands for 6 months last year
and all the work done with the radiator and support did something?

Last summer, I removed and had repaired the radiator support and
had the radiator re-cored. Everything up front and underneath was cleaned
up, with all of the ground connections found and cleaned, the headlight
wiring was frayed in a few spots.

They were also cleaned up and reconnected as well and the wiper vacuum
lines were also cleaned up and re-connected last summer. With the
exception of the headlights, everything worked.
