Question about 2003 Kia Sedona

2 Answers

Leaking lines There are two lines -about 1" in diameter- running to the right rear panel where the air conditioning fan seems to be along with other electronics; they are leaking a oil substance. can you advise if this has anything to do with my A/C? The air conditioning hasn't worked for quiet some time.

    the lines are leaking behind the passanger side tire along the firewall they have rusted through. does the motor have to be pulled to replace the hoses since the upside is behind the motor where it has rubber hoses clamped to it. Will it continue to leak if we don't use the ac or heat.

    what are the lines called where the antifreeze is leaking?

  • k_hutt Mar 25, 2009

    I had the same problem but I was leaking coolant. My husband just replaced the rear lines we were hoping that that would resolve our over heating problem but it still overheats at a stand still. As long as the car is in motion it does not overheat. Also even after replacing those lines the rear heat is still not working. Does anyone have any other suggestions?

An oil substance....hmm....are those lines hard or soft? If soft, I'm not sure what they are. If they are hard, sounds like they could be for your ac. Yes that could be the reason for your ac not working. And if you don't want to ruin your ac compressor, get those lines fixed asap. If I'm right, that oil is for your ac compressor. Needless to say, no oil, it breaks down. And on that new of a vechile, it will be expensive to replace compressor!

This must be the rear heat and ac unit. this must be coolant lines. the AC lines have one big line and one small line.
you can find where they connect near the engine and bypass them and not have rear heat.
have you been loosing antifreeze?

Smell of gas outside of car that is blown in when the air conditioning is running. It seems most prevalent near the right rear of car.Does not seem to be leaking though fuel gauge does seem to be dwindling...


take it somewhere with a lift. pay them a few bucks to put it up in the air and look for wet spots. touch the wet spots and sniff your finger, eventually one of those wet spots will smell like gasoline, follow the wet spot to its source and there you go. most likely a gas tank thing, filler tube, rusted spot on tank leaking, leak in the fuel line, etc. it is a fuel injected car, high pressure, so if leak is on the engine side of the fuel pump when it goes it will be a mess and a fire hazard. it is nearly 10 years old so you might want to just drop the tank and replace the fuel pump anyway if you are looking at any serious labor.

97 ford expedition. AC blowes out the defrost not panel. knob will turn off but air will only blow out defrost


The air control doors on your vehicle are vacuum operated and shift by themselves to a "default" position [which is defrost] if the vacuum is lost. I would suspect that you have a broken or leaky vacuum supply line near the engine somewhere which is preventing vacuum from ever reaching the control panel. Look for a broken or leaking small 1/8" or so diameter black plastic vacuum line near the rear of the intake manifold area on the engine. This line may go to a plastic vacuum reservoir or it might just go right to the firewall and pass through it with a group of other items [it varies from model to model] If you can't find it you might need to have someone at a service facility track it down for you. Should be a fairly simple fix. Good luck, hope this helps a bit!

LEAKING FLUID UNDERNEATH RIGHT REAR QUARTER PANEL, WHY?


Depends on what the "fluid" is. If it is brake fluid or gasoline or coolant you have a serious problem that must be fixed immediately. Gasoline is expensive and a fire hazard. Brake fluid implies that the brake system needs attention. If it is coolant and the vehicle has a rear heater there could be a leak in the heater core or the lines that run from the engine compartment to it. If it is plain ordinary water and the vehicle has rear air conditioning it is just the condensate that is produced when the rear air conditioner runs. It is normal and is no cause for concern.

Rear Air Conditioning


Check under the right side of the vehicle. look for green oil near right rear wheel area. sometimes the lines rub and start leaking. will have to replace lines if that is the case.

Squeal coming from pump which connect to radiator via hoses. This pump has a few wheel pulling for the fan belt to run when pump is not engaged


If the hoses you are talking about are the large hoses ((about 2"-2 1/2" in diameter) you are talking about the engine water pump) If they are small hoses (about 1" diameter stiff black hoses) the part is the air conditioning compressor. If making noise, it must be replaced, whichever component it happens to be.
