The 4x4 is controlled by a vaccum canister on top of the front axle, could be malfunctioning or vaccum hose is leaking, the heater box has a notched door that controls the heat & a/c output. Mine stripped & rounded the cam on the heater door making the a/c switch from cold to hot & back because the rounded cam on the door continued to rotate because it couldnt find the park position.

Does the Erg vacuum solenoid cause the ac switching from vents to defrost


the ERG shouldn't have anything to do with what vents the AC comes out of, rather the dash switch that exists for changing from defrost to main vents to floor vents controls what vents are used.

Depending on the make and model, it could be the control switch on the dash or the switch that moves the gears in the transfer case.

AC is only blowing through the defrost vents in the dashboard?


I think your problem is the head unit that selects where the air comes out ie. Face, floor, defrost, or hi-level face and floor. If that's not working then it will not let you switch location that you want the air to come out.

99 GMC Sierra 4.8 1/2 ton 2 wheel drive new body style ac does not blow cold air from the front vents on the dash? Still get some cold air from bottom by floor vents,


if both vents are blowing air in general then you may need to get your air conditioner recharged, but if the front vents aren't blowing at all then you may just have a jammed vent flap and you can fix that from under the hood next to the blower motor. check you rowners maual for the exact location

When i turn on heat or ac it runs on the defrost setting but wont shift to the vent or floor until the 4 wheel drive knob gets turned on 1999 f250 I heard this was a common problem is it the switch for 4x4...


you have a vacum leak in the 4x4 engagement system. there is a vacum solenoid on the passenger side next to the battery. should have 3 hoses to it I believe. check those hoses for cracks they go all the way to both front wheels. the ones in the wheel wells are usually messed up. if all hoses are good hook up a hand held vacum pump to each wheel they should hold about 15 hg on the vacum guage if not your wheel hub seals are leaking.
