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. .

sounds more like the thermostat may be failing. generally a water pump starts leaking out of the "weep" hole in the casting before it quits. just look at the front of the water pump for a greenish streak or an obvious leak.
if you also suspect you heater core may be getting plugged now would be a good time to back flush it to get rid of some of the gunk.

SOURCE: heater blowing cold air

My 05 sentra with 79k miles heat will warm up and then get cold after a mile of driving, we have tried to get the air pocket out, the mechanic stated he thought it could be a blown head gasket, another mechanic said it was a bad heater core. Any advice would be appreciated.

Heater wont blow hot air and won't defrost windshield or passenger windows.


Make sure that your coolant level is up with no air trapped,but it's probably a weak water pump or clogged heater core. don-ohio

My heater just stopped working, it still blows air but just not hot air, i checked the coolant and its fine, it had never over heated. so please help


check to be sure that the thermostat is closing, sounds like yours is stuck open, which happens a lot ,, if the water won't stay in the motor long enough to heat,, then you won't get any hot air coming out , follow the top radiator hose to the motor, under that housing is where you will find the thermostat , thay are pretty cheap, less than 10 bucks normally ,, I'd just replace it

A/C stopped working and blowing hot air. Is there a fuse to check?


In almost every case, when hot air blows while AC is turned on, it's an indication the system is low on refrigerant. This could be due to a leak in the system. There are do-it-yourself kits sold at most auto parts stores or a qualified service station can recharge your system (they have to check for leaks prior to recharging the system).

If you can hear the compressor kicking on and are still getting hot air, check coolant level. If coolant level is good and compressor is kicking on, you may need to change out your thermostat.

The heater is blowing warm (not hot) air


This could be your thermostat. If the thermastat is stuck open the coolant will not build up enough heat. When the coolant reaches your heater core it has not been superheated by the engine because your radiator and fan are contiuously cooling it. I would change the thermostat. That would be a good place to start. I hope this has been helpful.

97 Ford Econoline air conditioning and vent settings blowing hot


I know from experience that if the coolant is to low ( not just the freon levels in the compresor but the antifreeze/coolant level as well) the AC system will not cool and will blow hot. Check the coolant Antifreeze and freon levels, even with the Coolant being a little low my 1998 Ford E150 Van will blow hot. After you have ruled out of these possibilities and the chance it is the thermostat most likely the problem is what Ford calls the "Flap" it controls the air flow through the vent system when you switch from Heat to AC. When the Flap is working it closes off one systems air flow so as to not interfere with the current climate selection.
