Think I may have found my "Service ABS" issue.
Service ABS light is lit and throwing a code 63.
The ABS solenoid relay is open circuit between pins 85 & 86, so the coil is shorted.
It's NLA at GM, and I'm not having a lot of success online.
Autozone claims to have a replacement but it's a different manufacturer and a special order part.
Anybody got a spare?
