The door check is the piece that lies between the door’s 
					hinges and holds the door open at a couple places, keeping 
					it from blowing open & shut in the breeze. It looks like 
					this: 
 
					
					
					 
					
					
					
					
					
					
					***Before I continue, let me say that I replaced my door 
					check because it was clunking whenever the door was 
					opened/closed. This may not be a good reason to replace it, 
					as I found out. The new part did not totally solve the 
					problem, though it was a bit quieter. The real problem, it 
					turned out, was that the metal on the door where the check 
					mounts is stressed, and buckles a bit and creaks. I will be 
					looking into reinforcing the mounting point. 
					
					Ok, back to replacing the door check. 
					
					For this 
					project, you will need: 
					
					- 10mm socket & ratchet (a short extension is nice, too).
					
					
					
					Step 1) 
					Lower Door Trim Removal (driver's 
					side or
					passenger side)
					
					 
					
					Once that trim is off, you’ll need to pull the rubber seal 
					out of the way of the hole you will need to work in. First, 
					remove the wiring harness from the rubber (yellow). Just 
					grab the harness and carefully pull out – it is just wedged 
					in there. Next, just grab at the edge of the rubber and pull 
					out gently, but firmly (red). 
					
					
					 
					
					
					It will then look like this… 
					
					
					
					
					
					
					
					Now we’re ready to grab that 10mm socket & ratchet and 
					remove 2 nuts (red) & 1 bolt (yellow). The 2 nuts may stay 
					connected to the plate (green). 
					
					
					
					
					
					
					
					Next, slide off the plate. You can see in the picture that 
					my upper nut did not stay connected to the plate, but the 
					bottom one did. It appeared that they originally connected 
					the nuts to the plate on purpose, probably to prevent loss.
					
					
					
					
					
					
					
					
					Here’s what it looks like with the plate removed. 
					
					
					
					
					
					
					
					Finally, slide the piece out the hole where the rubber piece 
					is. 
					
					
					
					
					
					
					
					Here is the now check-less door and frame. 
					
					
					
					
					
					
					
					Installation is opposite of removal. Hope this has helped!
