84 dash brightness
I have a 84. My dash light sometime are dim. When I start the car they are nice and bright and then the dim. When I shine a light in the auto darkening cell it get bright and when I hold my hand over it it get darker.
I just think sometimes its to dim and sometimes its good.
I am wondering if it could be my ignition switch? Or is the normal?
thanks for any input

it is hard to tell on here how dim they are getting. but from what you said it seems normal. They are changing when you mess with the photo cell. Do you have anyone that you can compair it to?

The dash back lighting is much dimmer at night because you don't need much light to see the instrument panel. The photocell does nothing at night and the brightness is controlled by the rheostat on the headlight switch.
During the daytime, the photocell controls the back lighting.
You might want to take out the instrument cluster and look at the solder connections between the two PC boards. It's fairly common for the connector pins to get hot and cause the solder to crystalize -- bad connection.
For more info on the cluster back lighting see my article:
