Question about 2002 Nissan Altima

Heat intermittently working Nissan Altima 2002

I have a 2002 Altima. I live in Chicago so the winters get very cold here. This winter I've noticed that at times the heat goes from coming out hot to coming out cold. After blowing cold air for a few minutes, it will go back to blowing hot air. I am hoping that this is something that I can diagnose and fix myself. Any suggestions

Ok 2 cases there may be one that closes the valve that leads from the heater coolant, the second that the gate that divides the evaporator's heater is opened and closed.Tanks

You may have a sticking thermostat make sure you have enough anti-freeze in it and it does not have a air bubble in it give these websites a try www.alldatadiy.com and www.autozone.com if all fails stop by your local library and get your hands on a Haynes auto repair manual for your car wish you the best of luck Michigan Man.

2006 nissan altima won't start in cold weather


Do you have enough antifreeze in your engine? If the coolant is freezing up the engine will not turn over and your block can bust. You should always winterize your vehicle if you live in a cold climate. Check the coolant in your burp jug and radiator and see if it's frozen, if it is, you can try placing a small heater under the car or at the very front of the car as close to the radiator as possible to defrost it. You'll have to cover it with some blankets to keep the warm air in and be careful not to cause a fire! If you can get it defrosted you need to get it winterized a.s.a.p. if the engine has not been damaged. Hope this helps.

If there is plenty of antifreeze and it is not frozen up, then have your battery checked. Extreme cold & heat can kill a battery. Hope this helps.

Heater blows cold air at low speed and idle 02 nissan altima


I worked at a Nissan dealer for 18 months and we'd get a lot of these in. The cold heat at idle is accompanied by a sloshing noise from behind the dash - you've got an air pocket in the heater core. What we used to do was lift the front end of the car about 3 feet off the ground using the hoist and take the rad cap off. Then we'd run the engine at a fast idle (jam a screwdiver against the throttle stop to hold it fast or put a slight weight on the pedal if it's Electronic Throttle Body. Run the heater on full heat and the engine like this. You'll see the rad 'burping' as the air in the cooling system travelling to the highest point it can - the open rad cap. Top up with a 50/50 mix of coolant and water as you go. When it burps no more, you have a full cooling system and should not suffer any more "cold heat".

If you do this yourself, PLEASE use jack stands, block the back wheels and put the parking brake on!!!

Hello. You are in luck. I just had this same issue in my shop this week. We changed the thermostat, and replaced the coolant. Fixed it right up. Since you did not mention a new thermostat, that would be my next move, if I were you.

Nissan Altima no cool air blowing or hot air blowing


Hi!
It appears we have an Air lock scenario and you will need to perform a system Bleed.
Park the vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater on full and blower to max. When engine reaches operating temperature watch and listen near coolant filler, keep clear as gurgling and hopefully a boil over should occur. Top up with very warm coolant and wait as it may do it again.
Check for heat inside vehicle if warm replace coolant cap but keep an eye on temperature gauge as the ~Air lock may have moved on from heater matrix/core so proceedure needs to be carried out again from COLD.

A heating problem on a 2000 nissan altima


you can take a little time but you should definitely replace it soon if you have cold weather where you live.

Engines need to be warmed up by the coolant in the winter time.
