Question about 1997 Ford Windstar

Climate control troubleshooting

My van has both front and rear A/C. The fan blows and the compressor kicks in, but air will only come out of the defrost vents. No matter where you put the swith, air only comes out of the defrost. How do I troubleshoot the problem?

FROM LUSTYKID:

You probably have a vacuum leak in the hoses connecting to Temp Control switch. Remove it carefully and inspect. Those things have mini -O rings sometimes. Any leak in any of the hoses and things go kaput. Check to make sure no leaks in the diaphram also.
As for the person with heat in the rear only, you need to check to see if the door is closing and opening. Not sure if yours is also motor control. If motor control replace the motor that operates the door. Is probably stuck in the hot position. But before you spend money ensure there isn't debris keeping the door from operating.

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.

When front air is on rear heat always


If you have owners manual check that your climate control settings are as you expect them to be, if that makes sense. Some on Fixya do not realise they gave climate control , they think they have normal A/C and try to correct chimerical problems. Please check and repost

My climate control only blows out cold air but the rear climate control works as it should


Could be the controller or a faulty blend door.
The blend doors direct air thru the heater core and evaporator along with the vents. The controller uses electric motors to change the direction of air flow.

Rear climate control fans blowing cold


That sounds to me like your vent "tubing" is disconnected somewhere along the line. I am not sure exactly how it is set up in the vehicle you are driving, but I am certain fixing it will involve taking apart most all of your interior then putting it back together after a 10 minute fix.

Dual climate control


There is a thing called a blend door, it controls air temp, that is where the problem is, most common issue is the motor that operates the door fails.

AIR CONDITIONER


On most vehicles with front and rear A/C, the two systems are basically independant of each other just sharing the compressor and condensor. It is possible that the Mode Door (controls where the air flow is sent; ie: windshield, vents, floor) is out of adjustment or sticking.
