    I have the same problem. My 2000 Leganza blows air, A/C works just fine, but won't blow heat. It kinda blows luke warm air but only after it has been driving a while and if you keep the blower set to low...It's going to be a cold winter.

    Check the heater hoses to see if they are hot. They both should be hot. If only one is hot then the water is not circulating in the heater core. If they are then the heater core is bad. If it's not circulating then I suggest back flushing the system including the heater core, change the thermastat and fluid. It should then after engine is warm blow hot air.

27th Nov 2007, 15:49 To the above comment: You can't have a 2003 Leganza, because Daewoo stopped selling cars in N. America after the 2002 model year.
A non-operating heater could result from a thermostat that is stuck open, keeping the engine from getting up to normal operating temperature; but if that was happening then you would probably have a check engine light on too.
More likely you have either a stuck or broken temperature control for the heater. Temperature controls are either cable-, or vacuum-operated. Find yours in the heater hose somewhere and see whether you can move the linkage on it. If that causes the heater to work, then you have found your problem. If not, then you may have a clogged heater core, which would probably mean replacement (much more expensive than a thermostat replacement, unfortunately).
Btw, your mechanic does not sound too interested in figuring out what the problem is.

SOURCE: No heat

first make sure the radiator is topped off or full also the overflow is at proper level .. feel the hoses going into the cars firewall to see if they are warm or hot. if cold then the car is not letting hot water into the heater core inside the car . there is a control outside the firewall that might be at fault .

Hi Mike, Sounds to me as if there may be a poor connection somewhere in the unit or the cables plugging into it. Regards John

ECU port for 99 Daewoo Leganza


you mean the diagnostic port? All vehicles after 1996 use obdII and the rules for the location of the plug state that it must be accessable from the drivers seat. it could be anywhere from near the drivers door to the center console. It may be covered by a plate. get a good flashlight and good luck. You can also contact Daewoo at www.daewoous.com or call 1-800-323-9668
