Defective EBCM
 

The EBCM on my 2007 Corvette went bad in February 2018 (a year ago). GM delivered two parts to the dealer that were defective, They said it would be August 2018 before they could deliver another part. When August came, they said December. Now there's no date for delivering the part. They don't have a supplier. My car has been sitting at the dealership for over a year. The dealer located a company in Mesa AZ that said it could fix the part, but has failed to do so. Any suggestions/

Welcome to the forum. I seem to vaguely recall reading about a restoration service for Corvette computers. You might try an online search or checking with some of the aftermarket Corvette suppliers.
