This was at the best price I could find that had it in stock ready to ship. Relay was delivered in a couple of days and once I installed it I stopped getting the error codes.

Fit my 02 Duramax. Much more economical than buying the whole assembly from the dealer

Bought these on April 9 2018, had one original relay that failed and decided to change both while I had the controller out. They worked perfectly for a while. Now 8 months later one has failed completely with no contact and the other is intermittent.Very disappointed.
