Blower motor doesn't pump well even the fan switch on high

HI ANGELA,IT MAY BE YOUR BLOWER MOTOR RESISTOR,IT'S LOCATED NEXT TO THE BLOWER MOTOR,VERY EASY TO REMOVE,HERE'S A LINK SHOWING YOU HOW.

Check whether you might have bad connection or contact,or e ven bad switch.

I would replace the blower motor resistor first then see if that corrects this. The resistor is located next to the blower motor under the dash.

I would replace the blower motor speed control switch.

Remove the trim panel from under the passenger side of the dash. You should be able to see the lower motor and the connector. With the key on and the switch set to high wiggle the connector. If the blower motor starts to run faster and/or act abnormal when you wiggle the connector, replace the blower motor. This is a fairly common symptom and problem with these year full size gm's. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com! I have a tip on how to diagnose blower motors that don't work. It doesn't really apply to this situation but it may help you in the future. http://www.fixya.com/cars/r6571076-blower_motor_not_work

You describe a common occurance with the manual type A/C control knob/switch. Also, the blower motor brushes are also a common issue. The notion it's wiring or fuse is not a common occurance. There's a couple of things you'll want to inspect/examine before you start throwing money at parts. First, key ON, blower switch on HIGH, RH side under the dash, locate the blower motor housing & slap it firmly with your hand. If the motor starts running, then the problem is in the blower motor itself (brushes, intermittent contact or NO contact). If the motor does not respond after this (shock test), rig yourself a 12 volt test light and back-probe the two-wire connector (black wire and red wire) to see if the light turns on when the blower speed switch/knob is on. If the light comes on, you know you have power and ground applied/available at the motor itself, but it isn't working/running - therefore its the blower motor itself. If the light DOESN'T come on, then the problem is probably in the blower motor switch itself. To access this switch, you'll need to remov the vertical console. Remove the ashtray. at the bottom of the ashtray opening/cavity, there are two phillip head screws - remove them and set them aside. This console snaps/clips into place and is simply popped out to gain access to the A/C control module. Using your test light, check for power to the switch (Go to www.hmaservice.com and register your vehicle by VIN #.. you'll then have access to wiring diagrams, shop manuals, service bulletins, campaigns, illustrations and procedures, etc.) If memory serves, the manual A/C control switch can be purchased separately at any Hyundai Dealership Parts Department.

Hi,
The resistor block for A/C motor control is usually hot, that why it is place inside the blower box to have it cooled down by the air coming from the fan motor to the A/C and heater core.
Check your blower fuse, it might have a high amperage rather than the original 15 or 20 amps required capacity, that's why instead of the fuse to first to break up, the resistor burned down.
Hope that helps you out.
Thanks for using FixYa!

more than likely....blower motor resistor, normally located next to blower motor passenger
side under dash 2 screws & a plug

Hi!!
When the Blower Motor Resistor (controls blower speeds) goes bad, the blower motor works only on HIGH SPEED. REPLACE IT.
BLOWER MOTOR RESISTOR Removal & Installation

• Disconnect negative battery cable.
• Remove right lower instrument panel insulator panel.
• Disconnect blower resistor connector located behind right side of dash.
• Remove blower resistor screws and blower resistor.

To install, reverse removal procedure
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa!!

Hi.....
On your Vehicle the problem for the FAN speed is NOT the FAN switch.
99.9 % of this problem on cars is the BLOWER MOTOR RESISTOR.
The blower motor resistor give the speed to the Fan.
But on High speed the switch make a By pass of the switch using a Relay for the high speed.
The Blower motor resistor, is located Beside of the Blower motor On the passanger compartment.

If you replace the blower motor resistor you have 99.9% of this will solve your problem.

I hope this help on your problem.
Thank you for use fixya...
