SOURCE: nissan 2000 ac hot when idle

the a/c condenser has a fan in front ( there is actually 2 fans if you sit on the car it will be fan on right side ) if this fan does not
come on immediately when you are parked and engine in idle
there is a problem with power to it, or motor failure. If you drive it
on the highway and a/c operates fine that's because air is circulating though condenser (thats what the fan is supposed to do at idle or slow traffic)

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.

2005 altima blowing hot air


could be your switch, or you have a freon leak and there is no freon in the system. open hood and watch the ac pump and have them turn on and off the ac. if in engages then it is probably freon. if it doesn't check ac fuses.

Ac blowing hot air from one day to next and all fuses are fine


need to recharge the coolant in the ac compressor, you can now do this yourself go to auto parts store and get a can of refrigerant and the hose to do this real easy and only costs about 30.00 to do yourself. Or make sure you dont have your control set to hot.

2005 nissan altima heater blows cold air when stopped and blows hot air when going down the highway. What could be the problem?


Check your coolant level. If it is low, what you describe will happen. Water pump works faster as rpm's increase, managing to get hot coolant to heater core (highway speeds). At idle, pump is not working fast enough to get the coolant to the heater core.

2002 New VW Beetle is only blowing hot air out of vents even when set on cool. I was driving and I made a turn at an intersection and all of a sudden the cool vent air turned to hot air like I had the heat...


On the bottom of the air unit is the lever that changes temps. It likes to fall out of place.I propped mine back with a piece of half-inch copper pipe a couple of years ago.Remove glove box then panel on front side of console to access.
