Tapping noise from dashboard 2005 kia sedona while driving ac turned off

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).

SOURCE: AC not working on KIA

if you have freon full and got power to the relay the you need to check the radiator fan if working if yes the a/c cut off switch should be mounted on the a/c lines if it is two wires disconnected and jump the tow wires togather by small paper clips for few seconds and start the eng put the a/c on if started working good then you have a bad switch for 3 wires switch is to replace

SOURCE: 2005 kia sedona - no rear heat

Look on your dash on the ride side of your radio, there are 4 black squares, the botton three are usually blank, the top one says RR HTR, push that one in. If the heat does not work than join the club, mine has only blown warm heat in the last 2 years. I've had the rad flushed and all the rear lines replaced.

Testimonial: "Why is it the simple things are so hard to find. I had it on at one time, but it must have gotten bumped. Thanks for the reminder."

SOURCE: car turns over but wont start it is a kia sedona

the car will not start if the immo light is not lit. sometimes turning the key back and forth or removing it and locking then unlocking the car can sometimes remedy this.

SOURCE: Kia sedona. Knocking sound from Engine

I assume by now you have this problem fixed, but if not, or for the benefit of others looking for help, try replacing the coil on the #5 cyl as well as the injector. Ours did same thing, except fault code was on #2 cyl, so I got the parts from local parts store for about $150 total, and completed the repairs myself on my wife's 2003 Sedona. Now i can start on the rear heater issues, the knocking sound coming from the LF tire area while in motion, and replacing all brake pads. 92,000 on the odo. I'll spend the extra $ and go with the Honda Odyssey next time.
