Hi!
I have a problem with the housing in my c4 -88
When i turn on the ignition the lighting in the housing doesn't work and the lamps to the indicators are lit all the time. but not on the outside of the car. all the meters works fine but its hard to see them without any light in the housing.

Are you talking about the dash board?

You are talking about the digital cluster (Speedometer etc.)

The digital readout is all dark, but if you look really close or in bright light you see it working. But there is no backlight. Also, both of the direction lights as well as the High beam light indicators are on.

You have a broken ground in your cluster. This happened to my dad's 86 corvette... Real pain in the butt to fix.

This link explains it all..

You want the article with the following title:
The Digital Cluster Turn Signals and High Beam Lights are Always Lit

If you need the schematics for the different ground pins etc... they are also on that site.
