Whining noise and loss of power kia sedona - 2004 Kia Sedona

SOURCE: my kia sedona wont start just click when turned on

Couple of things to try.

1. Check that the battery connections are both clean and tight on the battery.
2. Check water level in the battery is above the plates that you can see in the filler holes.
Caution:
(Handle the battery with care as the water in the battery has been charged and becone sulphuric acid which will burn your skin. Do not get this in your eyes.)

3. Turn the headlights on then start the vehicle, and if:
a) the lights dim the battery is not connecting properly or faulty, or:
b) the lights stay on full it would the starter motor relay or solenoid (part of the starter motor).

Check our air filter. Nine times out of ten it is something very minor .If you have not changed your air filter in a while, this could cause the loss of power going uphill. On flat ground the vehicle does not have to work as hard as uphill. If your air filter is dirty, this will hamper the carb from breathing properly, thus no power.

i just had to have this fixed on my 07 sedona on the bottom arm for the doors there are litle lock solinoids that go bad i would take it to a dealer to have it checked for the switch you can turn the power off to the doors and open them manualy but they are hard to open because you are pulling the cable instead of the motor doing it and this will not hurt the doors
