SOURCE: 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.

SOURCE: 2004 NISSAN ALTIMA 2.5 NO CABIN HEAT..ENGINE AT OPERATING TEMP.

If the engine is not over heating than most lilely it isn't the thermostat or waterpump that is causing the problem. Check the heater hose coming out of the manifold and see if it is warm to hot. Next check the return line from the heater if it is still cold or moch cooler than the inlet, the most possible problem is the heater water control valve if this model has one or possible the core of the heater is plugg with slime cause by some antifreezes setting during the summer months while not being used. If this is the case than remove tihe two hoses and back flush the heater core with water pressure until it runs clear. I have had this problem before and this cured my problem. I also had to flush the engine and radatior also. Hope this help. .

SOURCE: nissan altima heater does not

I had the same problem with my daughter's 2002 altima. The blower would not blow hot air. The mech. said I needed a new heat box. Thankfully, I got on line. There is a little white plastic gear that is supposted to turn when you switch from cool to hot. It must get stripped easily. Easy to find. look under the dash from drivers side. Turn the hot/cool switch and you'll see it trying to move. You can manually turn it but when you turn the car off it automatically switches back to cold. The nissan guy was very nice. He only had to order the plastic gear. ($8.00). But, I did have to pay to have it put on the car. Some could easily do it themselves. Much better than buying a heat box (400.00 dollars) hope this helps

SOURCE: 97 Nissan Altima AC/heater fan only works on highest setting

Sounds like the blower resistor module needs to be replaced. Could also be the switch.

My 94nissan Altima car heater just stopped working, how do I know which part to fix to get heat again?


Check to see if blower is working by running 12v to it. If that works check if your heat/ac controls are working by looking at the area where the flaps are and turning the knobs/buttons. You should hear the flaps move or see the pins of the flaps turn. See if your heater core is working. Should be hot as coolant from engine passes through it.

HEATER WONT WORK


Given the age of the car I'd bet the heater matrix is blocked up.
When the car is warmed up look down the back of the engine and trace 2 hoses about 1.5 in diameter heading through the bulkhead. if these are roughly the same temp. ie hot then the matrix is blocked.
Even with correct coolant 5-8 years / 80k miles is the norm for these.

depending on the particular model and facia layout this can be a mornings work for a good diy or a major task for a competent mechanic.

If the vehicle has been run for any time without the correct level of antifreeze / summer coolant then the matrix will block up.

I presume you have checked the thermostat? When the car is warm, feel the upper and lower main rad hoses. The lower should be cooler than the top. Does the heat reflect the actual engine temp? Does the gauge read low all the time? Is the thermostat stuck open and the engine temp is low?

Finally, if you think the coolant is hot enough and the small hoses are as hot, are the heater flap controls working properly?

2002 nissan altima heater problem


have 2002 altima,blower works no heat at idle and very little heat when accelerating.I changed carbon cabin filter,made sure little gear under dash to temp knob wasnt broken,flushed and bled system.Nothing worked so checked hoses to heater core and found inlet hose was hot,outlet hose was not.So investigated this problem and came to conclusion heater core was clogged.An easy way to check is to get car to normal running temp. put on heater and blowers at full.Go under dash on passenger side where counsel meets firewall,this is where heater core core inlet and outlet aluminum tubbing go through firewall,you will be able to feel both tubes one closest to you is outlet, so if this one is not hot and and other is your heater core is clogged.I detached both inlet and outlet hoses to heater core from water control valve.Then I blasted water with waterhose and nozzle set at jet,first through outlet hose to blow gunk out,then through inlet hose until water runs clear.Reatach hoses fill and bled system.heater works great nice and hot!

I put a brand new heater core, radiator, water pump an thermastat but it still takes forever to blow heat out an then it doesn't get that hot.. what's the problem? my vehicle is a 1995 jeep wrangler 2.5 4...


Could be the heater bypass valve is stuck or the heater core is blocked.
I'd check the heater core first.You may have trapped air in the cooling system or the heater core may be partially plugged up. Engine coolant is delivered to the heater core through two heater hoses. With the engine idling at normal operating temperature, set the temperature control knob in the full hot position, the mode control switch knob in the floor heat position, and the blower motor switch knob in the highest speed position. Using a test thermometer, check the temperature of the air being discharged at the HVAC housing floor outlets.
Temperature Reference
Ambient Air Temperature 15.5° C (60° F) 21.1° C (70° F) 26.6° C (80° F) 32.2° C (90° F)
Minimum Air Temperature at Floor Outlet 52.2° C (126° F) 56.1° C (133° F) 59.4° C (139° F) 62.2° C (144° F)
If the floor outlet air temperature is too low, Both of the heater hoses should be hot to the touch. The coolant return heater hose should be slightly cooler than the coolant supply heater hose. If the return hose is much cooler than the supply hose, locate and repair the engine coolant flow obstruction in the cooling system.
OBSTRUCTED COOLANT FLOW
Possible locations or causes of obstructed coolant flow: Pinched or kinked heater hoses. Improper heater hose routing. Plugged heater hoses or supply and return ports at the cooling system connections. A plugged heater core. If proper coolant flow through the cooling system is verified, and heater outlet air temperature is still low, a mechanical problem may exist.
MECHANICAL PROBLEMS
Possible locations or causes of insufficient heat: An obstructed cowl air intake. Obstructed heater system outlets. A blend door not functioning properly.
TEMPERATURE CONTROL
If the heater outlet air temperature cannot be adjusted with the temperature control knob on the A/C Heater control panel, the following could require service: The A/C Heater control. The blend door actuator.
The blend door. Improper engine coolant temperature

2002 Nissan Altima


hello solangesolib ,

the altima's i have encountered , are extremely difficult to bleed the air out of the cooling system , sometimes we have to jack up the front of the car to (for lack of better terms) burp them , i have tryed flushing heater cores , replacing thermostats , to no avail , but the air pocket thing is a charicteristic of the beast . also , 1 other thing we see is the blend door actuator get out of sync with the hot / cold selector knob , the gear is down by the drivers right foot , in the open , easily verified , its like a slice of pie shaped gear , they do strip and / or get out of sync , then when you turn knob to hot it really isn't . between these two things, is all we have really seen be wrong . hope that fix ya .

There are a few things that can cause your car to run hot. Not enought antifreeze is one. It could also be your cooling fan is not working, a colgged heater core, colgged radiator, thermostat is stuck closed, leaky water pump, or coolant temp sending unit. Hope this helps.

2002 Nissan Altima - Heat doesn't get hot and doors get stuck


Did the switch break because it was stuck? If so, then yes, they will have to change actuators and doors. Does the fan work on all speed setting? If so then you do not need a blower resistor. The resistor pack only controls the current flow to change speeds of the fan.

No blower for heater 1993 nissan altima


It is very possible you blew a fuse. There are two 15 amp fuses for the blower motor, make sure you check both of them.
