One has to keep up on repairs and maintenance on old cars. The Corvette is showing its age too, after nearly 8 years on the road.
After the recent battery replacement, one of the TPMS sensors gave out. It was replaced at a cost of $80.
Now the door unlocking relay on the driver's side is sticking. The two options are to replace the entire DCM ($400) on that door, or try to replace the relays on the existing circuit board. Some homework is in order to find a suitable solution.
