Ok, I was coming home from working out tonight cruising at 35mph in 4th gear when I hear this clicking sound. I am almost positive this is the sound you hear when the power door locks lock or unlock. I thought maybe my door was unlocked and maybe this was some safety feature or something. But seconds later, it happened again. I checked and saw that my door was locked. However, this sound kept repeating at 10-20 second intervals for like 3 minutes until I got home. This is the second time this has happened to me. Last time it happened was the same street, same speed, same gear, around the same time.

Anyone have an idea what it is?

By the way, I have a Crimestopper alarm on the car. Could this be interfering with something?

Thanks for the help.
