Question about Cars & Trucks
What engine? On either there are two connectors going to two different parts on the throttle body. The sensor directly across ffrom where the throttle cables are attached is the TPS ( throttle position sensor). The part under that is the IAC (idle air control) valve. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

SOURCE: blower fan only works on high
CHECK THE HVAC CTRL FUSE.
WITH A TEST LIGHT CHECK THE BLOWER RESISTOR FOR POWER ON THE YELLOW, TAN, PURPLE, AND LIGHT BLUE WIRES. THE ORANGE WIRES CONTROL THE HIGH SPEED CIRCUIT. DO THIS FOR EACH POSITION OF THE BLOWER SWITCH.
THE BROWN WIRE ON THE HVAC CONTROL CONNECTOR 1 POSITION B COMES FROM THE HVAC FUSE 20 AMP. NO POWER ON THAT WIRE WILL CAUSE THE BLOWER TO NOT FUNCTION ON THE LOWER SPEEDS.

Hello! This indicates a fault with the wheel speed sensor/ABS sensor. Any major auto parts retailer can pull the details of this code (which sensor) for free, which will help you identify if the wiring is loose or damaged or if the sensor will need to be replaced. If you need to replace the sensor - you will need to replace the entire wheel bearing assembly, as the sensor is internal.
Thanks for using FixYa!

You could try replacing the idle air control valve but I would obtain one from a local salvage yard, its cheaper and you are not certain if thats the problem, another thing i would check is your intake manifold gasket where it meets the cylinder head, if tha gasket is cracked or leaking it will allow excess air to enter the engine and make it idle higher, the easiest way to verify this is get a can of carb and choke cleaner and spray it all around the intake gasket area, if the engines idling characteristics change drastically then the gasket is bad and needs to be replaced if theres no change in the idle I would start looking for vacumm leaks and the idle control valve issue, which you specified.
