Y You should check the filter goes on the floor vent.has to be change,and just in case it is a machine special to check air conditions,but not every one have it,the manufacturer or representative seller garage shop,they fixed but expensive

I have a 1998 ford ranger and the heat only on defrost vent

Sounds like your blend door actuator in not working properly.One controlls cold/hot mix air other redirects the direction of flow.You can go to your local parts store and see if you can get them to show you the rite part so you know what you are looking for.May be dealer only.Location may be on ither side of the trans. hump on the under side of the dash.Not sure on fords.If you can get it removed and run the controlls to see if it moves.Run it npart way with you hand and see if it returns to the same possition if at all.Problem may also be in your heater/AC controll unit.

No heat - ac stays on blowing through defrost vents

If you have the heater directed to the windshield, the AC will turn on. Move the control away from defrost.

AC.

Inspect all of the vacuum lines in the AC system under the hood. If one of these lines is cracked or broken the AC system will not be able to switch the vents over.

1998 F-150 4x4 AC always on?

My Ford ranger does this too. It's been a while since I read on this but if I'm not mistaken I think this is normal.

Almost sounds like the actuators are inop. depending on which style you have, some are electrical motors and some are vacuum. These control the mode doors which move to deflect air to various vents.

needs re-gassing because one line should be hot (feed) and the return cold , This is a specialist job do not attempt to do it yourself because its extremely dangerous with very high pressures involved

SOURCE: climate control system only blow air out defrost vent

there is a good chance that you blend air door is stuck closed over your heater core and therefore not allowing the heat to flow, also your door that opens and close your direction of flow from the floor ,das,vent and defrost.your going to have to remove the lower cowling of the dash on the passenger side analso some of the center dash to actually check to see if the cable,servo motors. are acuating the doors.the issue could be just a stuck door or a misaligned cable or that it came off. that falls under the mechanical side of probabilities. electrical would most likely be a faulty selector switch or a servo motor

SOURCE: There is no air flow

You need part GM Part number 89018675 or ACDelco 15-73596. The Mode Selector Actuator. What happens is the part is a CHEAP part POORLY designed and when it goes to turn the flaps inside the HVAC unit its the plastic gear slips instead of turning the flap!!!

Just to forward you you might want a deal to install this art for you unless your good at fixing your own vehicle, because you need SMALL sockets and a lot of patience to get this part in!!!

The part is ALMOST directly above the steering shaft for your steering wheel, so theres a lot you got to remove before you will even see them!!!

I only recommend you to have a dealer put this part in for you, unless you have your own service manual!!

Because there is 5 of these darn things and if you pick the wrong one you will have to do it all over again!!!

3 on the Drivers side and 2 on the Passengers side!!

But replacing this part SHOULD solve all your problems!! AS it did for me and i was having the same issues as you have described!!

Is it a new vehicle? I had a new vehicle that had the same problem. Answer was that the holes weren't punched out of the vent.

Check your vacuum pump located on the right side fenderwell. see if its running. Check the vacuum hose at the hubs for leaks or damage. repair if damaged. check for other vacuum leaks such as the grey hose going to the heater control valve.
