Question about 1995 Ford Econoline

Open Question


The in-cabin directional airflow doesn't work. I've had a look at the vacuum switch. There is no vacuum tube into the second inlet from the left (next to the black); and I get a vacuum noise - like there should be a tube there. When I block the black I can get air to the screen. But this is only temporary; and doesn't properly solve the problem. Any suggestions.

p.s. I had to describe the car as an econoline - because that's the only 1995 model that the product dropdown would accept. But the car is a utility (same as a pick up).

SOURCE: dpfe sensor broke in the REF tube

One hose is reference the other is pressure, the hoses are different sizes, do you have the factory high-temp silicone hoses required? they are different sizes so you can't mix them up, vacuum hose will burn up in short order, the failure of this sensor is almost always caused by excessive exhaust back pressure, you may have a cat converter starting to plug up.

2002 jeep laredo interior vents won't blow except

The mode control on your heater panel uses engine vacuum to operate the doors in the heater box. when the system loses vacuum, it defaults to the defrost setting. find the small plastic vacuum line that penetrates the firewall and leads to the engine intake manifold. Check the hose that attaches the line to the engine for cracking or looseness. If that is OK, trace the line back into the cabin. It should lead to the control panel. Check any tees or couplings for leakage. If it's good all the way to the mode control switch, it is likely the connection to the switch or the switch itself is leaking. With the engine running, listen carefully to the switch for hissing. It is also possible that the defrost door actuator is bad. If you can find the door, try applying vacuum directly to the actuator to see if it operates to shift the flow. If it doesn't, replace the actuator.

2005 ford escape 3.0 V6... the heater/defrost last winter was barely enough to defrost & keep you warm & now in the summer the A/C was barely cool...had the a/c checked recently by dealer they said...

Does your vehicle have a cabin filter? If so, recommended change interval is 15,000 miles. If you have not changed it recently and/or you park under tree's, I will bet that the filter has more leaves on it than your driveway.

Okay, I've dealt with this a time or two. Surely, the dealer checked or mentioned the cabin filter?!!
How about airflow out of the dash vents, and....wait for it....a vacuum leak. I'm sure the dealer mentioned and checked all this stuff. But just in case he didn't....try these:

With or without a cabin filter, debris can get into the system over time and partially clog the airflow thru the system. The blower motor must be removed and using a light and mirror, one can look into the duct work and see the blower side of the heater core, and evaporator, as well as the drainpan. They should be fairly clean. If not, you will need to have it cleaned out.

If all is good with the filter, ductwork, and blower, all that is left is the electronic's which work in tandem with vacuum. The blend door actuator could be stuck between hot and cold, A. because it's faulty, or B. its jammed with debris, or C. low vacuum.

All the controls and actuators and electronic's would take hours to explain. So, read the following and go from there.

It sounds like vacuum is not getting to the vent, heat and A/C controls. Find the vacuum can. It may be under the hood on one of the inner fenders. The "one-way" check valve is usually located in the line and close to the can, make sure it works properly. The valve could be the very thing that's causing the problem. Trace the lines back to the vacuum block at the intake manifold or fire-wall, and also back to where the line goes thru the fire-wall. Check the can for leaks or obvious holes. They used to be just a plain metal can, but it could be a plastic ball. Check the lines as you go, for breaks and rub-thru's. Move the controls thru all settings and listen for vent door movement. Worst case is a bad vacuum motor or air flow position selector switch, and/or a faulty Blend Door Actuator. If you have been driving around with the Temperature knob or control set at the same spot for months, move it from fully cold to fully hot several times and wait for the air temperature to change each time. This will help reset the blend door and vacuum control system. Hope this helps... Let me know what you find.

When the engine is cold,check the coolant level.

Make sure it's on max.


A coolant system should be flush every two years.


If you did a coolant flush recently then air pocket can be the cause of the un-even heating problem.

The DIY method is to drive you car onto a ramp or a steep hill.

Iet the engine cool off and top off the coolant tank.

Set MAX heat + MAX fan

Let the engine ran for 20 minutes wih the cap off and the trap air will escape from the coolant reserve tank,

Check coolant level and top off coolant when the engine cools down.

A shop will charge $75+ for this but using an air operated excavate tool!


A car with over 90K miles may experience linkage problem to the heater control valve.

The heater control valve (near the firewall) may be stick over time.

Open the hood and move the heater to max and min. Back and forth.

Clean and lube the linkage with WD-40 to free the heater control valve.

If it's a vacuum type heater control valve then cash for leaky vac. hoses.

Move the fan switch back and forth to re-new the electrical conductors.

Pass a vacuum over the control panel to prevent dust build up behind the console.

96 GT gets hung up on defrost

Sounds like you need to check the vacuum line that feeds the three vacuum switches controlling the airflow to the cabin. Find the vacuum distribution block. It located to the right of the master cyclinder and is mounted on the side wall in the corner. It has several hoses connected to it. The smalled line (1/8 in) diameter is the one you need to check. follw this line along the firewall to the other side of the engine and you'll see it connected to another connector that then feeds into the firewall. Good luck in finding a replacement line.

1996 ford mustang convertible ac blows cold only from defroster

Does it still blow out the floor and defrost when you set the switch to those positions or does it alway blow out the defrost no matter what? If you can get air to blow out to the floor, then it sounds like you lost the switch that controls the airflow to the vents. If it only blows out the defrost, then you probably lost the vacuum to all of the switches. When the vacuum is lost, it will only blow out the defrost. Check the smallest line on the vacuum distribution block located in the corner near the brake master cyclinder. That line provides the vacuum to control the direction of airflow within the cabin.

Switch on dashboard does not change air direction to flow & vents

Defrost is the default mode so if the system fais, you alays have defrost. The mode doors are controlled by vacuum motors. I would suspect a vacuum leak in the engine compartment on the hose going from the engine through the firewall and into the heater controls. Some systems have a vacuum storage canister that can also leak. The canister stores vacuum when vacuum drops going up a hill.
Or, you have a bad heater control head that is not passing vacuum to the vacuum motors on the mode doors.

Here's a diagram of the system for reference.
