DIC Switch Voltage
The DIC switch stopped working.
Is the IPC defective if I am getting 10v to 12v at the DIC switch? The purple wire is 5v the other 8 are above 10 volts. The gray (ground) is grounded.
Thanks

There are 7 wires for the DIC switches. There are an additional Black, Yellow, and Purple which do not show but must be for the lighting. For lighting, I can only assume Purple is a reference voltage and Yellow is power and Black is ground.
If none of the switches work it is most likely the IPC. I have worked on at least 6 identical cases and it was the IPC in every one. Normally switch issues are related to a single switch. I assume you have the schematic. If not, I can post.

I have a schematic that shows that I should have 5 volts to the switches plus the gray ground. My service manual does not show the black, yellow, or purple wires so I was not sure what they did. I pulled the IPC apart but could not find any obvious problems.
I can not find any rebuilt IPC's or any service that rebuilds them. I have seen some used IPC;s. What would suggest to fix the problem?
Thanks again

Well, not exactly correct. If you notice there is a resistor in each circuit so I don't know what the actual voltage is to each switch.
There are plenty of vendors that rework the IPCs, but they don't fix everything.
Still think the IPC is the culprit but could be something going on with the switch.
Recommend Marc at VetteNuts.net for any replacements, great Forum vendor here.

I Purchased a used IPC from VetteNuts for $100, 2 hours later the problem was fixed. I used the original DIC switch so it was the IPC. The voltage from used IPC was 11 volts so my assumption that it should be 5 V was incorrect. VetteNuts gave great service.
