Craftsman 3/8" Pro Air Ratchet Rapid Reverse 19888 - Answered Questions & Fixed issues
Craftsman 875188020 air leaks out the side only when trigger is pressed.
All air ratchets have an exhaust. Air in must go somewhere and it will go out the exhaust. Some exit beside the air inlet & some have the air exit out the side of the handle. If the air is not coming out of a defined air orifice, then you may have a worn out gasket where the handle meets the head or you may have a cracked handle. The handle unscrews but you must hold the head in a vise while you use a wrench or adjustable wrench to grip the end of the handle to unscrew it for inspecting the internals.
I have 2 blue point air ratchets that dont seem to work
Blue Point® is kinda-sorta a Division of Snap-On® Tools, however being labeled "Blue Point", Snap-On only gives them a 90 day to one year warranty, so Snap-On will not help you there. Since you got them at an auction, they may be frozen up as you suggested. I would place both the ratchets in ATF (Transmission Fluid) for a week or so and then try the air line to them again. Transmission fluid does wonders. We used to use it to clean our hands at Dealerships in the Winter to keep our hands from cracking and bleeding. It will loosen up most everything. In fact that's what I currently use in ALL of my air tools as the "few drops of oil" they suggest, before use. If they don't start working after a long soak, then to be cost effective to you, I would find a Harbor Freight® or another such store and buy a new one for as low as $15.99.
I hope this helps you.
