Are you sure it is the AC blower? a lot of modern cars have a temperature controlled radiator fan, this can run when the engine is very hot , even when the keys are removed. It is a safety feature to protect your engine.
(1) possible blown fuse. Note that fuses blow for a reason - seek out the reason, or it will blow its new fuse too.
The main fuse block is located inside the left side of the
engine compartment near the battery. There is also an interior fuse
panel located just above the left side kick panel.
Interior Fuse Panel The interior fuses simply unplug
from the fuse panel. Use the fuse puller tool provided with your car to
remove fuses from the panel. The tool is located on the back of the
interior fuse panel cover.
(2) possible blower motor dead. See maintenance manual excerpt below.
(3) possible blower motor relay faulty. Location of Blower relay: Under hood, drivers side, front engine area,rear of headlight housing; relay mounted on drivers side of radiator shroud.
1990-92 Mazda 626 and MX-6 See Figure below
Disconnect the negative battery cable.
Remove the glove box and the underdash cover.
Detach the electrical connectors from the blower unit.
Remove the blower unit-to-fire wall attaching bolts and remove the blower unit assembly.
Remove the blower motor fan-to-motor fastener.
Remove the blower motor-to-unit attaching bolts, then remove the motor.
Installation is the reverse of the removal procedure.
If the Blower is staying on high maximum blow then it is probably the a/c blower relay. The other thing it could be if not on maximum is the blower motor resistor pack. Lastly would be the blower switch shorted to power.
the car and turn the air conditioning on. Allow the engine to run a few
minutes so the air can cool. Check to make sure you have the proper
buttons selected. This simple step may uncover the root of the problem.
See if the problem is as simple as a blown fuse. If the
temperature controls on the dashboard seem to work correctly but have no
effect on the air, then this is likely the problem. Find the interior
fuse box in a Kia on the driver's side. It is located near the
floor. Remove the kick board to get to it.
Check the control panel next in your Kia . If the air
conditioning controls are not working at all, then the control panel is
likely to blame. Remove the trim plate surrounding the center instrument
panel. Detach the electrical connectors and remove the control panel.
Listen for the blower motor while the engine is running. The
sound should increase when the air pressure is turned to high. Remove
the blower motor by first unplugging the negative battery connection.
Find the blower motor in your Kia directly in front
of the glove box. You should be able to get to the blower motor without
removing the glove box. Unscrew the four screws holding the motor into
place and pull it downward
IF THE BLOWER MOTOR IS WORKING NORMALLY THEN THE PROBLEM IS IN THE DISTRIBUTION BOX OUTLET WHERE THE AC EVAPORATOR SITS. IF A VACUUM LINE IS OFF OR IF THE DOOR IS NOT OPENING YOU WOILL NOT GET NORMAL FLOW. LOOK UNDER THE DASH AND SEE IF YOU CAN SEE ANYTHING OBVIOUS. IF THE MOTOR HAS OVER 200 MILES ON IT A VACUUM POT CAN BE ADDED TO INCREASE YOUR VACUUM AND ANYTHING OPERATED BY IT (ENGINE VACUUM) WILL WORK BETTER. THEY CAN BE BOUGHT FOR ABOUT 15 BUCKS AND ARE INSTALLED IN THE VACUUM LINE FROM THE ENGINE THAT RUNS TO THE DASH. IF THE BLOWER IS RUNNING VERY SLOW EVEN ON HIGH SPEED THEN THE PROBLEM IS IN THE RESISTOR CONTROL FOR THE BLOWER MOTOR AND WILL LIKELY NEED TO BE REPLACED. GOOD LUCK.
