If the blower motor resistor is bad, the fan will run only on the high speed setting. In your case, you state you have no air coming from the dash vents, indicating that the blower is working. The control of air flow is done with vacuum-operated baffles that steer the air to the different possibilities. If it isn't changing with your different settings, you may have a broken or loose vacuum line or the very frail fitting on the vacuum reserve tank is snapped off - have seen this on GM stuff before.
The tank normally a cylindrical device 6-8" across and high. it should have two small fittings on which there should be vacuum lines. It is often located close to the firewall.

AC fan blows less air after extended use


Sounds to me the blower motor is on it's way out and should be replaced. Even though they sound like there working doesn't mean everything is ok with it there are different parts on it that could go wrong and they way to fix it is with another blower fan and not a bad idea to do the resistor at the same time located in the blower box with about 4 wires coming out of it with one or two screws holding it in place all is located under dash behind the glove box area.

How to fix the air conditioning


Hi there:
First I suggest to check is to be sure that the blower motor has power to it, it should have power directly to the blower motor. The ground is controlled by the resistor and the a/c switch assembly, if there's no power, then you need to check all the fuses. If there is power, then you can ground the black wire from the blower motor directly to a good ground and see if the blower works at high speed, if it doesn't operate, then the blower motor is bad and needs to be replaced, if it does, then you need to chase the ground wire through the resistor and to the switch.


You may still find the resistor blown, if so, replace it, be sure to replace the motor also, many times, a motor that is drawing too much current will cause a resistor to fail. If the resistor is ok then either the switch is bad or the ground is bad, you may have to manually follow the wires to find the ground point.

I have a 1990 sundance my backup lights and heater blower doesnt work. when i put the car in reverse the brake light and airbag light comes on and when i try the heater blower it does the same so if any...


no back up lights mean back up reverse neutral switch is bad.use a 12 volt test light see if power going to blower motor or remove blower motor hot wire blower motor see if it works if not blower motor need replacing.if blower works when hot wired it.problem could be in ac and heater control switch faulty also resistor or check blower make sure it getting good ground.you could have poor ground at blower motor or electrical wiring going to blower motor could have a short or open.

Almost no air comes from the ac vents but fan is on high. This happens on auto and also on econ.


The 1992 was prior to Buick putting cabin air filters in so there is not a possibility it is clogged. So more than likely your blower motor is going bad or your fan control switch is bad. Does this problem occur with heating as well as AC? Does it change if you switch between blowing on floor, face, window(defrost) If it doesnt change based on location of blow and type of air temp then I would start by turning fan on high and placing head (ear ) against dash in center of console area. Have someone turn fan knob from low to high with engine OFF...After goign from low to high and back a few times you can see if the blower motor is responding to signal from switch. Listen for a whine, squeal, rattle, or humm. A whine or Humm would indicate a bad blower motor... Squeal or rattle a bad squirrel cage/fan blower blades. If you hear no noise and no perceivable change in blower speed/noise then its possible your switch is bad. Unfortunately the only way to definitely diagnose either is to pull the switch from dash and use multimeter to test for voltage change and for blower motor to pull dash. There is a digital control unit for your car as well. Although rare sometimes the wires on this can loosen or it can go bad. But since you didnt state teh fan wasnt working at all and you are getting cool air, that woudl be teh last thing to check

I have a 2006 Grand vitara and the A/C or Heater does not blow air. What part is responisble for this.


FIRST CHECK HVAC FUSE AND BLOWER MOTOR FUSE AND RELAY.IF BOTH CHECK OUT OKAY PROBLEM COULD BE HVAC CONTROL SWITCH OR MODULE OR THE BLOWER MOTOR IS BAD.TO KEEP FROM SPENDING ALOT OF MONEY.THE HVAC CONTROL MODULE CONTROL SWITCH VERY EXPENSIVE.IT COULD COST $300.00 TO $400.00 DOLLARS.WHAT I WOULD DO IS REMOVE BLOWER MOTOR IN THE LEFT REAR TRIM PANEL.HOT WIRE TO BATTERY USING JUMPER WIRES.IF BLOWER MOTOR RUNS ITS THE HVAC SWITCH.IF BLOWER MOTOR DONT RUN REPLACE IT.IF THE HVAC IS BAD BEST FOR DEALERSHIP TO CHECK IT OUT.BECAUSE YOUR DASH HAS AIR BAGS IN IT. WHICH WOULD BE DANGEROUS.

I have a 99 Jeep Grand Cherokee Limited and the a/c and heat temperatures work but no air comes out of the vents. When I'm driving at high speeds minimal air seeps out of the vents but it never blows out...


Sounds like the blower motor relay and wiring pigtail. Junk yards are full of jeeps right now after Cash for Clunkers.Ready for the picking!
Just drive your to a junk yard and show someone there they will be helpful.

1998 Honda Accord interior ventilation fan has stopped working.


they are right the air conditioner has nothing to do with the fan running .. your air conditioner is operated by a pressure switch .when it gets low on freon it will not come on, which saves your compressor. your fan only blows the cold air the air conditioner puts in to the coils located inside your dash. which the blower then blows the air into the car.. now you are on the right track look some more you will find the round motor under that dash near the glove box and its held in there with usually 4 small bolts. and removal is easy if you can locate it.. one wire and 4 small bolts and out it comes .. you should be able to get one at a local parts store ..

In dash heating/air unit -


First check the fuse for the heater A/C then check the blower motor relay it is a silver unit mounted right on the heater unit by the blower motor, then check the blower motor resistors mounted on the outside near the heater core if they all checks ok i woud pull the control unit out and check the mail wires that were plugged in to see if there is current battery voltage should be present atleast on two of them then i would check if the black wire is a good ground!!!.
