What sounds like turn signals when I first open the door?

Here's the scene:

I get off work, walk toward my truck, push the Unlock button on the key fob, open the driver's door and always hear a "click click click" which sounds like the sound you hear when your turn signals are on. It stops before I can get in and figure out what it is or where it's coming from.

Anyone?

 

??????????????

Never heard that before...

 

Do the lights flash when it unlocks? I don't have a fob, so I wouldn't know.

 

Pretty sure it sounds like the turn signals because it IS the turn signals.

 

Like the hazard lights? It's always daylight when I do it, so I can't see if it's actually the blinkers or not.

 

Its the turn signals when you unlock the truck, they flash twice if u hit it once or four times if u double click to open back door.

 

If you have the beep disabled the click is more audible.

 

Crap. I didn't think about the lights flashing when you unlock or lock. I never actually heard them. I guess it depends on how close you are.

 

I have that noise and I think its relays under the dash under the glove box.

 

LOL, well......problem solved. Occam's Razor comes through again!

 

I also think when you go into 4 wheel drive it makes same type of sound you have to listen for it .

 

Other noise could be the door locks opening / closing but that's loud enough for all to hear .

 

yup

if you open door as soon as it unlocks that's the relay for the drl/parklight flash

it flashes twice
