    I've been having issues with my AC/heat only working on high, and not even operating on low, med, or med-high in my 06 PreRunner. After doing research, I found it was a problem with blower motor resistor. After taking it out, I noticed the wiring connecting to the resistor was burnt. I've read that many other people with Tacomas blow through these resistors quickly. Has anyone else with problems concerning the blower motor noticed this issue with the wiring in their Taco?! :confused:

    The terminal that is burnt is the High Speed setting.

    If your filter is clogged, the blower motor will have to work harder. It will draw more amps and cause that. It will also burn out your resistors.

    It's a little cover, behind the glove box, right above where you found the resistor. Look for debris in the blower cage while you have the filter out.
