Question about 1998 Ford Expedition

Air conditioning blows out of the defrost vents only

The air conditioning and heater comes out at defroster. Doesn't matter where I set it at. Speed and temperature work okay, just that all of the air comes out at defroster.

If this is the mechanical unit it is possible that the wire in the back has come adrift or the clip that holds the wire in position has come off and now the whole cable is moving.
Have a look at the bottom of the dash where the controls are fitted and move the control at the same time looking if there is any movement below the dash, take it from there

My air condition and heat works on defrost only sometime comes out vents last seconds didn't matter were controller set


Not sure what year, make or model vehicle is in question, but the issue is due to an actuator that has gone bad. Sometimes referred to as a mode actuator or blend door actuator. This actuator controls where air/heat will blow from (defroster vent, forward vents, floor vents or combo, etc.). Good luck. Ron @ Speed-O-Repair.

Sounds like the flap valve in your vent system that allows air to go to the defrosters is either jammed or broken. Unfortunately you will have to take the vent system apart to look.

1998 Chevy S10 pickup air condition compres is on instead of heat


First be sure that you do not have the controls set to defrost the windows since on just about all vehicles nowadays with the controls set that way the air conditioner will be turned on...even if it is not so warm outside. So...be sure that you do not have any of the controls set to defrost and that the heater is turned all the way on.

It sounds like though that the control for the vents is not operating properly. This is a combination of mechanical movements of the vent flaps and small "air motors" that operate the flaps. These air units are controlled by air vacuum taken from the engine compartment through tiny hoses. If the hoses get cracks, holes or come loose from their fittings then your vents will not move correctly so it is a matter of looking and tracing each one of the hoses to make sure they are fastened correctly, have not come loose and are not cracked or leaking. The problem can even be in the engine compartment where the hose(s) connect to the engine vacuum system...so it will take lots of looking carefully with flashlights etc....good luck.

When I turn my vent selector to defrost on the far right (air con off)the air conditioning comes on. The dash vents will blow ambient air, but defrost setting blows air con. Any ideas?


It's normal for the A/C compressor to come on with the defroster to dehumidify the air so the windsheild won't fog up under humid conditions. You can still control the air temp. out the vents with the temp. select switch.

Air conditioning blows through defrost vents only


AC blows where you have your control switch set,if it only comes out your defroster have the vacuum check at the blend air doors or if you have a faulty heater control unit.
