I just got my car back from the body shop today, where it was repainted, and the truck is acting funny. It will open from any button (incl remote) once, then every subsequent time it makes a little noise but nothing happens. If I turn the car off/on again, the button will work again one time. Any thoughts on what's going on? Thanks

 

After playing with it, turns out it I can open the trunk about once every 30 seconds. I think it's probably the actuator getting old... anyone have experience replacing? Looks pretty easy, just wondering if there are any tricks/traps?
