Cordless Drill: No Reverse
if there is no reverse on your cordless drill, check either the lever or the switch. Once you have determined the part that needs to be fixed you can now use our expert guide to repair it yourself. Check your owner's manual for specific advice regarding your model.
Levers
To replace the lever, first remove the end cap on the drill then remove the two screws holding the transmission to the motor on the side of the transmission, where all of the housing screws are facing upwards, securing the cover to the housing. Next, remove the screws securing the cover to the housing and pull the cover off. Pull the trigger switch up enough to remove the forward/reverse lever out. Install the new lever and make sure the tab on the switch aligns with the post on the switch. Make sure all wires are in their proper channels so they do not get caught when reassembling the cover back on the housing. Finally, put the end cap back on.
