Getting enough heat from my used 2000 elantra

I think I got good heat last season but not now. The light for the air sometimes comes on when I am fooling with the buttons. I do not have a manual.

    I have not had a chance to check the fluid levels yet.But the consensus is that that is the problem of little heat. I will confirm real soon. Thank you.

The light for air should come on with your defroster on, Be sure first your radiator is complete full while it is cold and also the coolant resivoir is at the correct level. Good luck, low coolant will definetely make it blow cold. Hope this helps, Merry Christmas

Code P0118 for my hyundai elantra 2008, is it good to remove the thermostat, especially during HOT season here in saudi arabia?

The thermostat not only allows the normal heat cycle but it also allows the coolant to be able to cool itself before getting returned to the engine block.. If you remove the thermostat then you are not giving the coolant enough time to cool itself before going back into the motor. This will actually make the vehicle run hotter then cooler. I would recommend looking into the lowest temp thermostat available for your vehicle and look for an additive to help cool better..

Hyundai Avante (Elantra) green

a small rubber vacuum pipe connecting to the injector system / inlet manifold. Sometimes this pipe perishes and allows air to enter thus decreasing the vacuum. The engine then cuts out. It's simple to check and replace the tubing where necessary. You may also notice the engine cutting out when traveling at speed and one suddenly slows down.

I recently had the factory stereo replaced in my 2000 Elantra. The person replacing it supposedly knew what they were doing but now I barely have any heat. I have no front or rear defrost. Air blows out...

I don't either. The person could have cut, pinched, unhooked any number of things to create the problem you are having. Have you gone back to him and discuss this? I don't think I would let him look at it again as he may screwup more things on your car.
Is he a legitimate business with a storefront?? or just a backyard pro??? You may want to contact the Better Business Bureau and file a complaint. Be careful, there are a lot of IDIOTS out there who think they are qualified installers .. . .

Good Luck.

2000 Cadillac STS: Engine starts but will quit almost immediately. Sometimes will start and run, but then stalls out after moving about 20 to 50 feet in gear. The vehicle had this same problem at this...

That should usually be ither the mass airflow sensor getting dirty if so use carbeurater cleaner to clean it out ir its another air sensor ,just look along the air intake pipe ..and use the cleaner to clean the sensors

Car oveheats when in stop and go traffic or going

All fan comes on that means all temp sensors as well as circuitry are working. The culprit is that the engine has poor coolant circulation to cause this problem. When you on the freeway the air help to cool the engine, but not in a case of stop and go. There are 3 things can cause this problem: a bad thermostat, a bad water pump or a bad radiator. These 3 things can be all together or just only one of them. A radiator has all vertical small tubes inside to carry the coolant passing through and dissipating heat through fins outside. When it gets clogged up, coolant becomes stagnant hence heat is not dissipated causing over heat. The same thing happens when water pump is not turning to propel the coolant in the loop. If a brand new radiator was installed last year then focus on the water pump. If a rebuilt one was installed then it is questionable. Don't ever use a rebuilt one, it is saving only the part but cost a bundle for later labor and headaches. Good luck checking the 3 things to find out a root cause.

2000 hyundai elantra inside room heat

Almost every car(including yours) has a flow through ventilation system which means even with the air turned off air will still come through the vents. Its hot because of outside temp and engine temp. 
Basically just push the recirculation button and it will stop.

2000 Elantra Overheating

First when vehicle is cold like in the morning check and make sure that the vehicle has enough coolant/ antifreeze in radiator and reservoir. If coolant is need use a 50/50 mixture of water and antifreeze. You will need some time to do this let car run at idle until the temp guage is in the middle NOT+ normal operating temperature. At this point if the thermostat should be in the open position. Let vehicle run and check to make sure that radiator fan comes on. This should come on when guage is about midway/half way. If temperature rises above half going to h/hot and fan doesn't come on, you either have a BAD FAN BAD FAN SWITCH BAD FAN RELAY OR BLOWN FAN SWITCH FUSE. You will need to check all of the following I will help if its needed. If fan comes on and doesn't go off and vehicle continues to get hot even with fan running. Feel radiator hoses and see if the lower radiator hose is cool/cold. If it is you have thermostat that stuck closed. Replace thermostat and fix problem. If all the above is good and vehicle continues to over heat. THE BAD NEW IS THAT YOU MAY HAVE A BLOWN HEAD GASKET /CRACKED HEAD /BROKEN WATER JACKET. Basically you will need a HEAD JOB at least a head gasket. ONe tell tail sign of this is oil looking like milkshake/chocolate milk-a creamish while residue in oil or antifreeze. Contact if you need hel0p. Good Luck and thanks for using FIX YA
