2002 kia sedona is loosing coolant.....within 2 days after filling the reservoir to FULL, it went a little more than halfway down to low . No leaking on ground. Sometimes smell coolant inside van after...

The heater core is leaking into the heaterbox under the dash. Which is why you smell antifreeze/coolant inside. After a while (if left go too long) you'll notice antifreeze on the floor/carpet and possibly running out from under the vehicle as it flows out of the drain for the air conditioner (the heaterbox has a drain in it to let out the moisture produced by the a/c)

Losing coolant about 1.5 Lt per short trip , had heat now I have very little even on high , I'm thinking heater core ??? Not sure where on a 93 is the core??? It's a 1.3 thanks

The core is located inside the heaterbox, this is located inside under the dash but i would locate the leak first, a bad heatercore will leak inside the carpet or leak out the drain, if its full of coolant then you may have other problems, try reving the engine and see if the heat gets hotter, this may be due to a bad thermostat or plugged core, the core can be flushed with a waterhose, remove the hoses going to the heater core and use the hose to flush it, go a few times both ways to flush out, but you still have the coolant loss problem, you will have to preasure test the cooling system and look for a leak, hopefully it not bruning it, it exhaust gets into the cooling system it will cause loss of heat depending on how big a leak and would explain the coolant loss, theres a test that can be done to see if its exhaust entering the cooling system. hope this helps, good luck.

You have a bad actuator motor, this car has daul zones, one for pass and the other for driver, there are two actuaTOR motors that control the door for heat or cold air the driverside is bad, this is located on the heaterbox, heres a picture of it but take note there are about four of these motors you will need to move all controls until you find the one that doesnt move then that will be your bad one it should be in the center of the heaterbox,ab232dc.jpg

Heater core replacement. how to do it.

This is a hard one, frist evacutae ac system then remove ac lines from core and coolant lines from heatercore, you will need to remove all dash components radio heater controls cluster etc, then drop steering column, i would remove the neg batt terminal before starting this job, unbolt shaft and remove column from truck you will need to disconect all wiring to column at the base atthe main harness, then remove glovebox, next is to unbolt the dash, take a good look there are many bolts that are hidden, the main ones are at the ends of the dash at the bottom, two on each side, get some help and remove the dash or pull away and tie up, move it to get enough room to remove the heaterbox. next is to remove connectors from the heater box, then unbolt the box there are a couple of bolts also in the rear firewall in engine compartment. remove the heater box and open box and remove the core, reverse to install.

Heater fan only works on setting medium and high

This is caused due to a bad blowermotor resistor, the resistor is located to the leftside of blower motor on pass/side under the dash. remove lower dash cover and you will see resistor, first remove connector from resistor then connector to blower motor, next remove two screws holding resistor in heaterbox and then slide out, heres a picture of resistor to help you and also a diagram to show you the location of it this show an open heaterbox and resistor goes in from the bottom. hope this helps.4bfae0c.jpgb913ad6.gif

Fan does not work in position 1 2 3 works great in position 4

From the scenario that you have just described; more than likely your blower motor resistor pack has failed. On the highest setting, the blower motor will have no resistance from the resistor pack allowing the motor to turn the fan at full speed; however, on the lower speeds, the different resistors are what create your different speeds by varying resistance in the electrical circuit.

I have an audi a4 avant the temp guage is normal but the heater is blowing cold air can you help

common problem, heatercore needs cleaning, remove both hoses going to heatercore and run water through one hose at a time, for about 30 seconds,use water hose with a nozel spray with hose fully open , many places would just sell you a heatercore which would cost about $1000.00 when all it needs is a backflush,( cleaning) good luck, hope this helps.

Dual Temp on 2000 Dodge Caravan

Sounds like a "mode" door issue. Either the door is broken or the motor that operates it is faulty. There are very few wiring issues with these motors, so I'd guess the door motor. Unfortunatly, the door is located inside the heaterbox and is not accessable without dash and heaterbox removal. This is a job for a qualified technician as the a/c system must be drained first. If the problem is a motor, then some are accessable by removing the panels aound the heaterbox. Listen for the door movements while operating in a quiet setting. You should be able to hear the door move if the motor is operating. Listen close, it's quiet.
Hope this helps, let me know if I can do more.
