So, the last two times I took my car to the Toyota dealership for service they told me I needed a new cabin air filter and they could do it for 39.95. My husband said he could do it under $20.00. So, today I bought the filter for $13.99 at Auto Zone and decided to watch a YouTube video on how to put it in and do it myself. Five minutes later, I have a new cabin air filter installed plus $10.00 I found in a bank envelope in the glove box. (The filter installs through the glove box). So, total cost = $3.99...and a sense of accomplishment!
