Question about 2002 Mercury Sable

1 Answer

My Air cond, heat and vent doesn't work at all on my car. I have replaced fuses and the blower motor. Whenever I put the new motor in it would run then blow the fuses. Could it be the compressor?

No, the compressor will NOT cause these fuses to blow. You have a SHORT in your electrical system. you have a HOT wire getting into the Ground for that system

SOURCE: HEAT/AC blower motor stopped working

It's even odd that you were getting a step-type voltage when you first checked.
Many speed regulators are simple tapped resistors with the switch selecting which tap is connected to the motor.
More elegant controls would use a semiconductor (transistor) and a few other components to supply step-variable voltage to the motor.

To determine which is used on your car, you will at least need the electrical diagram for it, preferably an aftermarket service manual - Haynes or Chilton should be available at least in the US and Canada.
Those will contain not only the electrical info you now lack but possibly instructions that will aid in locating the controlling circuit.
I suspect that circuit is faulty; if the resistor type, it will be a device with mulitple taps, if solid state, a few parts on a small board.

SOURCE: My air condition is not blowing air out the vents.

Sparking meaning your socket maybe not secure or lose connection. sometime the carbon brushes in blower worn out and need to change.

SOURCE: 200 Cougar blowing headlight fuses

First look for a short or where a wire is exposed and fix that with electrical tape.

If you can not find it, then often I will put a Re-set fuse that does not blow but resets and costs about $5 at Autozone.

Good luck, J

SOURCE: No AC, heat, or vent

its sounds like the Blower speed controller, its located under the hood on the heater case. reach down a wiggle the connector, its under the heater hoses and attached to the case. If it starts the blower fan working get it replaced as it has a bad board.

Heat or A/C does not work in my car?
Either you have a blower motor FUSE that has gone bad "typically the problem" or you have a burned out blower motor. Usually the cause of a blown or burnt motor if not a Fuse, Is caused by the vented air from outside letting debris like sticks or leaves,acorns etc. enter the fan box. If ANY of the mentioned items get caught in the "blower box" then it will usually blow the fuse and or burn up the blower motor. Start in your fuse box and look for a burnt fuse and replace with same size fuse. If it blows the new fuse quickly then you have debris in "Blower box" that will have to be removed before adding yet another fuse. I have had the same problem and I found a bunch of leaves in my "Blower Box". I removed the leaves and replaced the burned out fuse. And I have had no more problems with the blower motor blowing air.

Hello from cold Kentucky.
The system uses a fan switch, resistor, and probably a high blower relay.
In the high position, the switch powers a relay that powers the blower motor. Any lower speed goes thru the resistor.
The resistor is on the firewall or under the dash depending on if the truck has air cond.
You can look up a blower resistor on the auto parts websites to get a visual.

My blower motor works but is not blowing out the vents on dashboard, only vents by windshield and side vents but not from dash...how should this be fixed....some vacuum hose ??
You have a loss of vacuum from the engine, first check under the hood and make sure the vacuum storage tank is not damaged and leaking and it has vacuum in it when the engine is running. If all that is ok then move on to the line that goes inside the truck and verify it has vacuum.

No air is blowing in my 2004 Nissan Maxima. I put 12 Volts directly to the blower and it starts blowing. I checked if current was coming from the feed wire and it was. But when I plug it back in, it...
The engine oxygen sensor code is a different maintenance item and has nothing to do with the cabin blower.
If you have a clogged vent, dirt-loaded heater core or stuck air door, the blower may be running while installed, but no air is moving. You did not say whether the blower was left installed or removed for your test with an independent power source.
If you have voltage on the connector to the blower, but it doesn't run when it's connected, then you have a bad connection in the connector or an open ground. Check for tarnish or dirt buildup on the connector terminals. My favorite means of removing light tarnish is a pencil eraser, but for the heavy tarnish I usually see on automotive electrical equipment I use Scotch-Brite abrasive sheet (not the kind on a dish-cleaning sponge, the kind used for metal polishing). If the male terminal is a flat blade, you can clean the female terminal by wrapping a strip of Scotch-Brite around the end of an ignition file or similar stiff strip of metal and running that into the terminal. If it appears the female terminal blades are spread too much to make reliable contact with the other terminal, try pushing them together with a jeweler's screwdriver.
It's also possible there's a sensor circuit (temperature, airflow or closed-loop motor speed control) that controls the blower that isn't working properly. What happens when you try to run it at full speed and maximum heat or cool?

If nothing is coming out, put your hand on the blower motor under the glovebox and put the fan on high. You should hear and feel it. If not you may have to replace the blower. Dont\'t replace it till you verify it is getting power.

Heater/air cond blower only works on high. any
It is the Blower Motor Resistor located behind the Glove Box on the dash. Remove the Glove box to access. It is mounted against the fire wall. This is a common problem. My 2002 did the same exact thing.
1. Disconnect the negative side of Battery.
2. Disconnected the Electrical Connection to the Resistor.
3. Remove the bolts/screws. I believe they have 8mm heads, there should be 2 of them.
4. Replace with new one.
5. Reconnect the negative side last.
6. Test System before putting the glove box back in!
7. Enjoy the CONTROLLED HEAT!!

2001 BMW 330i..Fan for AC/vent not working?
it's either a fuse or it's a bad blower motor, it could be a bad blower motor resistor but usually you'll get either high or low only, so if you have nothing on any speed, high low etc, and all the fuses are ok chances are it's your blower motor.
