Dashboard lights not working intermittently

Hi,

When you say dash lights, are you referring to the lights which illuminate the panel or do you mean specifically lights like warning lights, parking brake light, and so on?

If it is the lights that illuminate the cluster, do the interior lights (dome lights) do the same thing? When you say flipping the switch several times, are you referring to the headlamp switch or the ignition key?

Let me know.

Hi,

Since they work at times, then we know it isn't a fuse related issue. So, either we have a weak connection at the instrument cluster or a weak ground.

If you look at the attached pics, they show power (via a black/orange wire) to the instrument cluster. Also, it shows the rheostat ground for the lighting. What you need to do is first check to make sure the power supply to the instrument panel lighting is tight, not damaged, and in good condition. If it is, then we need to confirm a good ground under the dash.

Here is a link that you may find helpful when doing this:

If you look at pic 3, it shows the physical ground location with the cluster removed. (G31)

Let me know if this helps or if you have other questions.

Take care,
Joe
