How to change blower motor resistor on 2008 Saturn Aura XE
A blower motor that only works on certain speed settings could be the result of a faulty fan speed switch or blower motor resistor. If only one single speed works (usually HIGH), chances are the problem is a faulty resistor. Blower motor resistors can vary greatly in price depending on if the A/C system is Automatic or Manual. For example, an automatic A/C resistor costs around $175 while a manual A/C resistor only costs about $25. These two parts are not interchangeable; the correct resistor must be used for the type of system that's being repaired. Thankfully changing a resistor isn't too big of a job. The process starts by removing the right "close out panel" which is the cover under the dash near the glove box. The cover is only held in by retainer clips so no tools are necessary; just pull and remove. Next, disconnect the blower motor resistor connector and inspect for a melted condition. If damage of this nature is seen, a blower motor resistor pigtail will need to be installed as well. Finally, remove two screws from the resistor and the part will come loose from the HVAC box. Installation is as simple as reversing the removal procedure.You can read more here: https://www.yourmechanic.com/article/how-to-buy-a-good-quality-heater-blower-motor
