Blower motor blows on high only - 2007 Kia Sorento LX 4x4

94 CHEVY Silverado ????,heat/ac fan not blowing. K1500?????? Hear clicking when selecting l'm, SET high but not blowing! WITH AIR OR NO A/C? FIRST IS FUSES, MAKE SURE THE BLOWER FUSE IS NOT BLOWN.
EASY NO? CHECK ALL FUSES FIRST. ON ALL ELECTRICS FAILING OF ANY KIND.
BAD FUSE, BAD WIRINIG , BAD CONNECTIONS. OR EVEN BAD RELAYS TO THE BLOWER OR BAD SWITCH BLOW.
THE OLD CARS , HAD A SPEED BLOW , RESISTOR BLOCK
THAT FAILS ON ALL SPEEDS BUT HIGH, SO ITS NOT THAT.
OWN A VOLT METER????
HERE IT IS, ANY OF THIS CAN FAIL THIS OLD
WE USES A VOLTMETER TO FIND THE POINT OF FAILURE.
A SHORTED BLOWER MOTOR CAN BLOW LEFT SIDE TOP
FUSABLE LINK.RIGHT FUSE BLOWN MAKES THE CONTROLLER DEAD.

That is the blower motor relay, probably . You have all speeds but high ? High speed has a direct path to the blower motor through a high blow relay . All other speeds go through the blower motor resistor assembly . This relay is part of the blower motor resistor assembly > That is if you have manual HVAC system .
Blower Motor Resistor Assembly (CJ3)
Under the right side of the I/P mounted to the HVAC box next to the blower motor.

Here's a link to the blower motor resistor,usually they go bad causing you not to be able to use all speeds,it's located next to blower motor,two screws may hold it on.http://www.autozone.com/autozone/parts/2002-Ford-Taurus/A-C-Heater-Blower-Motor-Resistor/_/N-jhcdrZ91tag?filterByKeyWord=blower+motor+resister&fromString=search Here's a link to the blower motor.http://www.autozone.com/autozone/repairinfo/repairguide/repairGuideContent.jsp?fromSearchPage=true&pageId=0996b43f8036e0aa&partName=Removal+%26+Installation&partId=0996b43f8036e0aa

Hi Ken, I'm glad to help! A/C Blower problems like your, where the blower only blows on HIGH and later stops working all together is usually the "BLOWER MOTOR RESISTER" That is where I would start. Ken, If that does fix it. I would replace the blower motor as well because its usually the high resister within the motor that actually causes the problem with the resister. The Blower Resister on most vehicles is located on the passenger side near the motor. Some are right beside the motor, others are behind the glove box in the housing. Hope this helps and have an awesome day Ken.

Have you replaced the blower resistor . some times they can cause the fuse to blow . You may need a muiltmeter to test the current draw on the blower motor circuit. the draw should be less then half of the rated fuse .( 20 amp fues draw is less then 10 amps) You did not say but does the blower work on high only or the lower speeds with out blowing the fuse ? if it does work on low or high with out blowing the fuse i would replace the blower resistor

The blower motor needs to be replaced. Also if it only blows on high the blower motor resister block may need to be replaced as well.

IF THE BLOWER MOTOR ONLY WORKS PN HIGH THEN YOU NEED TO REPLACE THE BLOWER MOTOR RESISTOR LOCATED ON THE SAME HEATER BOX AS THE BLOWER MOTOR

If it blows only on high speed, it is the resister.
If it does not work at all, check fuses first. See owner manual for location.
Then check blower motor by jumping 12 volts from battery to blower motor. Make sure ground is jumped too.

If it works now, it's the control panel. If not, it is the motor.

Blower Motor —Front Removal and Installation

1. Prepare the vehicle for blower motor (19805) removal.
   1. Disconnect the battery ground cable (14301). For additional information, refer to Section 414-01 .
   1. Remove the air cleaner assembly. For additional information, refer to Section 303-12 .

1. Detach the speed control servo.
   1. Disconnect the electrical connector.
   1. Remove the bolt.
   1. Position the speed control servo aside.

1. Position the coolant expansion tank/windshield washer reservoir aside.
   1. Remove the screws and the nuts.
   1. Position the coolant expansion tank/windshield washer reservoir aside.

1. Remove the blower motor.
   1. Disconnect the vent hose.
   1. Disconnect the electrical connector.
   1. Remove the four screws.
   1. Remove the blower motor.

Heater Blower Motor Switch Resistor(s)
The front heater blower motor switch resistor has the following features:

• The assembly is located in the engine compartment on the evaporator housing (19850) next to the blower motor assembly (19805).
• Three resistor elements are mounted on the resistor board to provide four blower motor speeds.
• Depending on the heater blower motor switch position, series resistance is added or bypassed in the A/C blower motor circuit to decrease or increase A/C blower motor speed.
• An overheating device (thermal limiter) will open the resistor coil circuit when the temperature reaches 121°C (250°F), interrupting the blower motor operation in all speeds except high.
• The thermal limiter cannot be reset and is not serviceable.

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.

blower motor resistor maybe why it only blows on high
