Open the chuck fully and look inside, there should be a screw there that has to be removed to remove the chuck in view of the fact that it is a reversable drill and the chuck cannot be screwed off like a conventional inudirectional drill.
I am assuming you are talking about
not being able to move the "Mode Control Collar" and unless you can
get it out of hammer mode, you will not be able to change the torque collar
either.
If you feel comfortable taking it
apart AND its no longer under warranty, my best guess without seeing the tool will
be part# N026313 Gear Case Assembly. It costs about $80.00 US
Hi i have supplied a drawing and a parts list link to the drawing for you here:

Hope that was ok.
There is a screw in the bottom of the inside of the chuck. You have to loosen it with a quick, sudden turn while keeping pressure( as the chuck wants to turn with it). Putting the drill in its slowest gear helps increase resistance some.
Bit of a nuisance, really but what can you do:)

Yup, that is what happens. You can lessen that by really cranking it down, but it is an issue with most hand tightened chucks, and does not indicate a mechanical failure. I sometimes miss my old, heavy Milwaukee wrist-breaker with the keyed chuck. If it is just too much to live with, you could get a drill with the click in hex chuck or put a Jacobs keyed chuck on your hammer drill.
Anyway, I hear where you are coming from and share your frustration.

Save the battery and charger and forget the drill. I blieve the motor woul cost you at least half price of new. Go to the dewalt replacement site to find out
Possible reasons for this behavior:
Blinks Long (Red Light): If your battery is too hot, the charger will blink the red light rapidly and for an extended duration. To prevent this, ensure that your battery is not exposed to direct sunlight or excessive heat. Give it some rest to cool down.
Blinks Short: If the battery is too cold, it will blink short and fast. This could be due to prolonged exposure to cold temperatures or the battery being idle for an extended period. Allow the battery to charge for a while or bring it to room temperature to resolve this issue.
Blinks Very Fast (Doesn't Go Away): If the light is blinking very fast and persists, it indicates that your battery has gone bad and needs replacement.
A photo would greatly help with your issue, are both wires still attached to the capacitor?? in not, the capacitor must be replaced with one of the same value,
if the capacitor is ok, look for a wire with solder on the end but nothing else attached to it, or a solder point on a card with a hole in it or a solder joint that has broken free from the card,,, if you can solder well, and have the equipment,. it is good at this point because You'll need to re-solder them back together,,
again a photo will help me greatly in telling you exactly how to fix

Reverse and Forward Mode: Try putting the drill in reverse mode and hit the trigger, then forward mode. If that doesn't work, tap the tip on the driveway but don't slam it. It should release .
Use a Wrench: First, make sure that the chuck is in the locked position. Next, use an allen wrench to loosen the set screw on the side of the chuck. Finally, unscrew the drill bit from the chuck .
Remove Chuck Collar: Use a wrench or pliers to loosen the chuck collar and remove it from the chuck. Then, use a screwdriver or other tool to remove the chuck jaws and any other components that may be blocking access to the stuck drill bit. Once these components are removed, you should be able to access the drill bit and remove it from the chuck .
It's going to be a zener diode, that's the easy part, you will need to know the voltage as well, only way to know that is find a good charger and measure the voltage drop across the diode with a multimeter or find a schematic.
Here are the wire placements for the switch of a DeWalt DWD520 hammer drill:
The red wire from the motor goes to the top left terminal on the switch.
The black wire from the motor goes to the top right terminal on the switch.
The white wire from the power cord goes to the bottom left terminal on the switch.
The black wire from the power cord goes to the bottom right terminal on the switch.
It's always recommended to double-check the manual or contact DeWalt customer service for confirmation, as wire placement may vary depending on the specific model and year of manufacture.
