There is a manifold that "T"'s off from the front evaporator unit at the firewall and feeds the rear compartment area of the vehicle and it has a leak from there to the rear evaporator,soon it will lose all the R-134a and you won't have any cool,you need to find the leak under the vehicle where it comes down from the firewall evaporator and find this leak and repair it

1995 wind star min van blowe cool in rear and hot air in front plenty freeon fues are good


I would check the blend door actuator. If the door is open all the way, one direction, the air blows over the heater core. All the way in the other direction, the air blows over the evaporator. Anywhere in between, a blend of hot and cold for temp control. That explanation is a little simplistic. the info is for ford windstar.

Kia Sedona- center and third row heating vents blowing cold air

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.

Hi John,
Your right with your diagnostics, you have a blend door problem. If your switching to cool air and it is still hot then you also have a heat exchange unit fault, this is the component that changes the water flow from hot to cool by shutting off. If it is not operating correctly this will give you constant hot air no matter where you temperature switch is positioned.
As for the warm air while the engine is cold, sounds like the blend door is still open to atmosphere tempreture and if it is hot outside will pull that hot air into the inside of the vehicle.
Have the heat exchange valve checked, and the only way the check blend door operation is to remove the wiring from the blend doors and have the circuit tested. If the circuit is ok then the blend doors will need to be replaced.
Hope this helps

More than likely, you have a blend door actuator problem. Locate the faulty actuator under the dash, usually on the firewall, and replace.

How can I determine if my compressor is out on my


If you still get cold air out of the rear vents but the front only blows hot air you may have a bad temp door actuator in the dash, it may be stuck on hot and not able to move to cold air. However if you are low on freon with a truck that has front and rear ac then there will be a temp diff between the two. If it is hot air out the front like the heat is on then you have that actuator problem but if it is cool air about the same as the outside air temp then you may be low on freon.

Yukon A/C, rear blows cold, front ducts a LOT warmer.


There is only one A/C system split into 2 zones. Check the blend door actuator, it may have failed in one position or something may be jamming it. Also check the control panel in the dash, My 98 yukon did the same thing, no matter what temp you selected for the front it would blow at about 70 degrees. There is a circuit board in the control panel that gets corroded and one of the circuits controls blend door operations. Have a look.
