And every other person that has contributed to this section of Corvette Forum. ie; the HVAC display fix.

I have the electrical gremlins we all experience and have been working on them for about a week now.

I have cleaned all of my grounds except the two on the engine block.
I have replaced the ground bus plugs with soldered ring connectors.
I have cleaned the contacts in my ignition to hopefully remedy the no start issue.
I fixed the broken plastic tab so now I have HUD again.

I have not been able to fix my EBTCM.
I thought I may have been able to do that but when I took it apart one of the 12 female contacts pulled out of the board.

I soldered it back as well as the 5 solder points listed in the repair thread but I think it is fried.
It does not communicate any longer.
I was hoping the ignition switch repair would help with better voltage but that was not to be.
All of the grounds in the plug ohm zero.
I have the correct volts at all of the fuses and power wires, cranked or not the volts are consistent.

2003 A6

10 PCM P1571 H C

28 TCS NO COMM

When I clear them they come back.

I have done all of the trouble shooting I can do.
Any other input is appreciated.

Thanks again
Joey.
