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.

Van blowing cold air

It has air in the line. let ir idle with the radiator cap off for a little while and the air will work its way out. You may have bigger issues, but I do not think you need to clean heater core because you get heat sometimes. Do you see a lot of bubbles when you take the radiator cap off when running, head gasket if so.. You can take the cap loose while the engine is running, but not after you stop it, it will be to hot. Good luck

Ce lancer coupe wount idle

Has the battery been disconnected right before this happened? How many miles are on it and which engine do you have in your Lancer? The 2.0L or the 2.4L?

check your water level for your raidiator..fill your water up to maximum level under bonnet..the pipe leading to your radiator and water, pump with hand while the top is off to release any trapped air and screw back on.

My car smells funny in my mitsubishi cedia lancer 2000 when driving and it stalls some time and the car turns off when i took my car to get fixed there was no problem with the smell but when i went to...

Possible some wiring is burning or melting from under the dashboard have it checked again, the smell does it seem like burnt rubber or plastic?
Have it checked since you mentioned that the lights has gone. see the fuses as well just to be sure.
Better get an expert check it to be sure that nothing will be missed on the issue. If it is a wiring issue then the best thing is have the electrical rewired for best results.

Idle drops and some times the car dies.

Most probably not related. Remove inlet tube to intake and where throttle plate is visible examine for sludge or carbon buildup. If present use Carb cleaner or similar to spray clean then wipe out sludge and excess fluids with towel. This can help with unstable low idle speeds

Banging noise from front end during turns

Something is broken, and your car is UNSAFE to drive.
Get it towed to the local dealer, so that they can fix it, before you crash!

Replace water pump

Testimonial: "I also was leaning towards w/pump as culprit. Called owner of car and he is going back to dealer to get rectified no matter what! Problem 3 yrs old!"

Looks like the heater/aicon box got problem in directing air from the a/c evaporator to heater core.
The flaps that closes and open when you need the heat seems stuck or not working.
Check on that too!

You neat to get your heater changed asap. Clearly even the dealers are not able to solve it, so that means it is done with. unless u have not got it checked by a reliable dealer..
