Hi im new on this just need some help.

Went to start the car this morning and battery was totally flat so called AA out. They come out and checked battery and said battery is fine you have a drain somewhere could be that you left a light on.

After they left was checking the car from inside, while sat in the car i locked the doors with the key fob after around 1min i could hear a clicking sound coming from the glove box sounds like a switch CLICK CLICK.... CLICK CLICK this just continues until i unlock the car and it stops, not sure what this is, if anyone can help would really appreciate it, thank you.
