Is it manual or auto temp control? if it is manual the blower resistor is probably bad if it is auto there is a fan speed controller that is probably bad

High speed doesn,t work on heater switch.


Pull the heater control panel out of the dash and inspect the blower speed control switch, look for signs of a burnt connector to the switch, it will be discolored looking, if this is the case replace the switch and install a repair connector

Why would front console blower fan only work on high?


There is a resistor somewhere that cuts the voltage down for slower speeds. High speed runs on a direct circuit.
You need to find that resistor - - may need a shop manual.

My lower fan speed don't work except for the high, the fan high speed stay highest


Hello sanjuis24
It sounds like you've got a bad blower motor resistor. The resistor is located under the right side of
the dash at the blower motor. A new resistor is not very expensive and it's a fairly easy DIY.
Hope this is helpful

01 grand.prix ac fan switch only works on high. has a duel temp controller when you turn fan off the only way fan comes back on is to move the temp controller levers


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!!

I only get the fan to work on high speed, the lower speeds do not work


Hi!!
The Blower Motor Resistor also called Manual Temp. Control resistor), is fried, replace. The price with floor console $25 and without floor console $65. here is a pic.

the resistor is located on the blower motor housing, fastened by two screws. It is the part where the electrical plug connects, the plug on the pic. goes to the blower motor.
A HELPFUL - 4 THUMBS rating for this solution would be greatly appreciated. Thank you for using FixYa.

Heayer doesn't work


The resistors provide resistance in the circuit, dropping voltage to the blower motor to slow the motor speed down. On high, the blower receives full voltage through the blower relay.

If you had High but no other speeds, then the resistor pack is usually the culprit. If you have all other speeds but high, the most common problem is going to be the blower motor itself, relay, or the switch panel.

You can check this by turning the fan speed to "high", unplug the blower motor, and check to see that you have roughly at least 12v at the plug. If you have 12v, that means the switch panel is activating the relay and the relay is working. Over time, heat kills the magnetic properties of the magnets inside an electrical motor. Without enough magnetic energy, you may not get enough opposing force to spin the rotor full speed when the windings energize, but still enough to spin at lower speeds.

Another thing you can check is the connector at the blower motor and the switch panel. Sometimes these will heat up, start to deform, and cause a bad connection. The bad connection may be able to handle the lower current draw on low speeds, but the higher resistance from the bad connection won't be able to handle the higher current while in the full speed position.

Hope this helps, keep me posted. be glad to help you get your heater working again soon.

Air conditioner doesn't work


problems yes low high and high low are usually caused by faulty defective clutch coil or defective thermostat...electrical issues can be cycling switch pressure switches ambient air sensor or fin switch ( evap temp sensor)
Mechanically it could be clutch,or compressor the symptoms are not good... srry hit me back if you got some manual gauges and wanna run pressure test diagnostics..
