How to improve ground for A/C Panel Lights?

[Henrik]

As I finished reassembling the A/C panel the other night I had a hard time making all seven lights come on and stay on. They were fading in and out like christmas lights. I soon realized that the ground is poor. Looking at the electrical schematic it looks like they all share one common grounding point. If so, where on the car is that?

I know some of the wires ground to the Blower Motor assembly

Don't have a direct answer to your good question.

You can look at this thread to see which grounds are in that neighborhood or perhaps are even called out for this particular circuitry.

As you may see in that thread, some folks would tell you that if any particular ground has deteriorated in your car then you would be well advised to check/renew all of the other grounds sometime soon as preventive maintenance.

Thanks Ryan and Rich. The thread seems to hold much of the info I am in need of.
