Hello,
Just bought a 2004 Pacifica 6-Cylinder 3.5L V6 24V SOHC.

This doesn't always happen but when it does and I try and start the car it does a really rapid clicking sound (Kind of sounds like when you're stripping a screw head with an electric screw driver). After a few attempts at this it try's to turn over and after some more of the clicking it finally starts, sluggishly though.

Now my question, is this a BATTERY or STARTER or ALTERNATOR problem? any suggestions are appreciated... Thanks a lot,
Wes

 

The quick answer to your question is "maybe."

It could be any of those, or it could be a bad (corroded) connection between any of them. The cheapest and easiest solution is to check the wiring connections first. Look at the battery connections, If you see corrosion (white fluffy stuff) take the connection apart and clean it up with a toothbrush and a solution of baking soda and water. Then take a wire brush and scrub the connecting surfaces until they are bright. Follow the heavy cables to the starter and look at those connections too.
A weak battery can behave like that also. Take the car to Advance Auto Parts or Auto Zone and they will test your battery. At four years old, it might be time for a new one.
Those are the two most likely sources of the problem. If you can rule those out, it might be a bad alternator or starter. It's possible to test them, so I would do that before replacing them. Talk to the people at the parts store about testing them. You will probably need to remove them from the car for testing.
