I bought this car new in April 2003, it's always garaged, rarely sees rain, and only has 32,000+ miles to date. She's absolutely like new, and You'd be hard pressed to find another in this condition....near mint, inside and out. Every so often the lock actuator on the driver's door fails to function with the electronic door or key FOB controls. This issue has been ongoing since the car was 2-1/2 years old. I took the car to the dealer some 3 times for this issue, and they could not replicate the problem...always seemed to work fine for them. About 3 years ago at the urging of a friend who's a GM mechanic, I checked all the wiring and switches (4 doors) for proper connections/shorts etc, plus, I ordered and installed a new GM actuator, yet the issue continues to this very day. It's an intermittent problem and sometimes the locks work great for days, then suddenly, the issue crops up again. Here's a fly in the ointment: sometimes the actuator refuses to lock the car using the master door control or the key FOB, but if the car is started (with the doors closed) and put in gear, the actuator will lock down all 4 doors....then other times, the other 3 doors lock down and the driver's door won't. Sometimes the actuator can be persuaded to work by repeatedly rocking the master lock switch, other times, it's no go. Any input, GM folks???
