Question about 1998 Ford Escort

2 Answers

I have a 1998 Ford Escort and the A/C only blows through the defroster vents, I also start smelling like something burning if I try to use it. I had thought it was due to a vacuum leak but now I need

The lack of air flow through the other vents started suddenly, the A/C cools well, just up through the defroster vent only, I can't find the vacuum tubing that goes through the firewall so, I can't tell if it is due to a loose vacuum tube or if it is as the guy in the parts store said, that valve

Bad electrical door blend actuator. Not a vacuum activated door. Check under the dash to the right of the diver in the center of the air vents or on the passenger side under the dash and you should see the actuators with electrical plugs on them. You need to find the one for the defrost and replace it. Good luck.

SOURCE: POSSIBLE LEAK FROM THE TUBE CONNECTED TO THE FIREWALL.

pipe going to the fire wall is usualy the cabin heater. for the time being there should be 2 hoses going to the fire wall coolant in/out. remove them from the pipe on the fire wall and blank them off or if the hose is split replace them. it could be the heater core but that usualy leaks into the cab.

Chances are the electronic/digital HVAC control unit is bad. This same problem happened to me and I had to replace the entire unit. The dealer wanted to charge $800 for just the part! After I freaked out on them, they found a used one for less than half. Sorry, but there's no easy fix here.

SOURCE: PROBLEM WHEN SELECTING THE DIRECTION FOR THE AIR

Sounds like you have a supply vacuum problem. When you lose supply vacuum to the control head it defaults to defrost.

Why when I start my car is there an odor coming from vents that smells like something is burning, and my Air Conditioner still blows, but it only blows out hot air. 2008 Chrysler Sebring. Help?


have an accredited ac shop as an ac cannot produce hot air only cold air so that means that the ac is not working (leaks low on gas etc). The hot air is from the heater in the car and the smell is probably wire overheating or the resistors are burning.

Poor air flow through defroster vents


Got kids? Years ago, mine loaded the defroster ducts with toys, candy, etc.
Otherwise, please create another post and identify the year, make and model vehicle you're talking about before posting your question.

Could be the blower motor or the blower motor resistor. Take the blower motor out, power it and see if it works, if it does then replace the resistor.

Air, either heated or cooled only comes out the dash vents, cannot redirect air to any other vents.


The most common cause of your problem is the blend door actuator. This controls air flow from defrost, vent, floot etc. In most cases, replacing the blend door actuator will fix your problem. It's commonly located above or behind the heater vents on the floor of the cabin.

I HAVE A 2002 FORD TAURUS 3.0 ENGINE. MY AIR ALL OF THE SUDDEN HAS STOPPED COMING THROUGH THE VENTS, BUT STRANGELY ITS COMING OUT OF MY DASH VENTS. I HAD STOP LEAK AND FREON INSTALLED AND STILL NOTHING,...


If you cannot change the air flow from the heater vents, defroster vents, to dash vents, etc. as your control switch indicates the problem could be a loose vacuum line. It could have come loose from the engine under the hood. If not you will need to remove the control from the dash and check for vacuum at the control. If you have vacuum there you will need to replace the switch,

Ac is blowing out of defrosterandnot panels in the dash. Air is cool cold air will blow out of rear seat panel/vent 1998 ford explored


The most common cause is a bad blend door actuator which controls air flow throughout the cabin. When air flow only flows from 1 section (either floor, vent, or defrost) it's an indication that the blend door actuator is either stuck or broken.
