2006 Toyota Corolla with OEM Denso...

after 1 year and 2 weeks and only 6300 miles...from my sister's car...they have been doing road construction near where she works for that whole year plus time...

her complaint was a noise coming from the blower motor and poor output...this was sucked into the blower motor fan...removed and replaced with a new FRAM True Air from Walmart since it was Sunday...cheapest and best CAF I could source locally...a good reason to check your filters

It always amazed me the amount of crap those cabin filters pick up
(Probably a good time to check the under-hood Air Filter)

To help the filter, tell her during construction zones put the climate control to recirculate the mode. This closes the fresh air and minimizes the dust on the filter.
