SOURCE: 2003 Mitsubishi Eclipse GS blows cold air in heat mode.

ok here we go and you aren't going to believe it...
I replaced the thermostat step one

I noticed that I had a small leak at the engine side of upper hose fixed that by taking it off and cleaning it and putting the hose back on Step two

then while refilling the reservoir with coolant i found that the hose that was supposed to be in the fluid was curled up on top and not sticking down in the fluid where it should be.
played with the hose until i got it to fall down in the reservoir where it should be Step 3

I started the car with the radiator cap off and let it run until it got to normal operating temp. and keep filling the radiator with fluid until the level stayed constant. Then put the cap back on and test drove. Everything worked fine haven't had that much heat in awhile and it kept blowing hot even when i stopped and let it idle for ten min.during test drive. Checked reservoir when I got home and had to add a small amount of coolant but not much.

I really think that the hose in the reservoir not being in the right place and pulling air into the system instead of coolant is the real culprit of this drama, but i replaced the thermostat to be safe.

Mt car blows cold air but not hot i replace the thermostat and added antifreeze but it still no hot air its for a Mitsubishi lancer 2003


there are two hoses than run through the firewall to the heater core. With the car fully warmed up those two hoses should be about the same temp. If one is hot and one is significantly cooler that the heater core is likely plugged. The hoses can be removed and the heater core can be backflushed with a garden hose. do this several times alternating between the inlet and outlet of the heater core. reconnect the hoses and see what happens. Worse case scenerio you'll need to replace the heater core.

No heat blows cold air


In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car.

AC/Heater control valve :Lancer 2003 Misubishi


The sliding switch on the console is stuck in the cold position and the knob is pulled off. Use pliers to jiggle the switch as best you can. Feel under the center console and you probably will find the cable that is hooked up to the flapper. You'll know because when you jiggle the cold/heater switch at the upper console, the cable will move slightly. At the hookup of the cable to the flapper down under the console (passenger side) try to work the flapper loose to the open (or close) position. At the same time work the sliding switch (with pliers). The flapper will come loose and function properly. Try not to knock of the AC button like I did in the process. It flew off some where under the passenger seat. I'll find it sometime before summer. Ha.

Lancer ES 2003 Hot/Cold knob won't turn. Snaps back to where it previously was. Mechanic said would be very expensive to replace all cables and doors opening and closing air ducts. I'm wanting to try...


You have a broken mounting at the end of the cable,at the housing thats why the temp. control knob doesnt work,you can remove the center console to gain access to pivot the broken piece manually and try to modify it so you can attach the cablr

Freeon is good dont know what else it could be. when its cold out the ac works fine but when its hot it doesn't blow cold? WTF


The ac will blow sold when its cold outside.It is just the air from the outside. You need to check to see if the ac clutch is turning when the ac is switch own.You may have a bad ac compressor

I have no heat in my 2003 Mitsubishi Lancer. When


The cable that pulls the cool/heat switch on the a/c gets weak and it doesnt allow the dial to switch over to heat. You can see that cable and the way its supposed to work on the right side of the gas pedal over it. I usually just use my foot to push that switch over to heat and reach with and pull on it with my right hand to cool.
