Ah, the open road. The weather's good, the highway is clear, the wind is in our hair... and what's that sound? Motor vehicles may be more reliable generally than a generation ago, but parts still wear out and vehicles stop working correctly. Zach Edwards and his team at Ashland Automotive make a living correcting things that go wrong under our hoods. Zach visits once a month for a segment we call The Squeaky Wheel, to take your questions on car care and feeding, and otherwise talk shop. Join in
