A flexy shaft with a claw & magnet may work. They're a few dollars at parts stores. Also, try magnet on a string or lightweight chain, but make sure the magnet won't fall off.I was working on my dashboard area and I lost two philips bits into the windshield / dashboard vents. I heard them roll a little after they went in. I fished around with a magnet on a stick but no luck. Anyone know if there is an easy way to recover them?
Just a guess, but if you can find the blower assembly, that may be an easy place to access the duct from below by removing the blower.I was hoping someone knew where the vent connects under the dash and if it is accessible from underneath.
