You probably have a leak in the cooling system. The best solution would be take it to a garage and get it fixed because unless you are an experience mechanic you would probably have a hard time finding the leak as it could be very small.

I have a 98 mazda 626 an the a/c blows out hot air. How can i fix this?


Nope.
The coolant only cools the engine and produces heat for the cabin in the winter.
You need to find out if the compressor is working when the engine is running and the ac switch is on.
I could be low on freon or have an electrical problem.

2000 NISSAN 4X4 P/U A/C SYSTEM WILL BLOW COLD WHEN OUTSIDE AIR TEMP IS COOL, WHEN HOT OUTSIDE AIR BLOWS HOT.


your auxillary fan is not working. this fan is responsible for cooling the freon that is being circulated in your cooling system... check if there are any loose wires in front of the engine bay.

the auxillary fan is located right beside your radiator fan.

I'm having trouble with my ac on my 2007 Hyundai Tiburon and I had it recharged but it still does the same thing. It runs cool for a few minutes and then it blows hot air again. Do you know what I...


Yes, Have a qualified Hyundai Service Technician properly diagnose this A/C problem. There are too many possible contributors which can create the symptom you describe. Among them:
1. A/C control head malfunction
2. Triple pressure switch malfunction
3. Evaporator thermostatic switch malfunction
4. Evaporator icing over
5. A/C Compressor inefficiency
a. A/C compressor clutch slipping
6. Clogged condensor
7. Malfunctioning expansion valve
8. Air Box mode door opening when it shouldn't (or closing when it shouldn't), etc.
9. Over charged/Under charged refrigerant

Ac not blowing cool air. How many fan are there in the engine department? how does the fan system work to cool the condenser?


The fans are inportant but the regular raditior fan will do it and the road speed of the car will blow enough air though the codenser to make it cool if it's going to. Does the compressor turn on? if it does do the lines hooked to it get hot?( the small one) and the big one get cold? The condenser should get hot, Hot enough to burn you and the freon level may be wrong and or the compressor isn't pumping. ( brocken inside)

My climate control starts blowing hot air while a/c is on


Make sure you have fully charged AC sytem first, if so Im sorry to tell you this but this is a difficult deal.you may not be able to correct this without taking it to a repair shop with gm scan tool. Reason being the actuators for the hvac that most likely are malfunctioning from either them or another component being bad , require recalibration.The other reason would be the body control module related.It would have to be scanned for U codes which can effect the hvac control.Sorry but thats what I know.

Rear air conditioning setting


It sounds like your rear temp. blend door is malfunctioning. You might could get a known good controller from (ebay,junkyard,craigslist) then plug it in. If this does not fix, it is probably a blend door actuator issue.
