Do you have a 2 door or a 4 door Accord? The front or the rear?
No problem, Here you go. Click here. This is a pretty good blown apart picture of the front drivers door. This should help you out. These are fairly simple to replace. The hardest part is getting the door panel off. Once you get the door panel off, you will see 2 10 mm bolts that connect the door glass to the regulator, remove these first and lift the glass straight out. Then there are several 10 mm bolts that connect the regulator to the door. You will need to remove them and the regulator will come right out. If you need anything else, or get stuck, let me know.
I see that problem all the time. If the rubber around the glass looks wrinkled near where the mirror bolts on, you will need to replace the rubber to solve this problem. If it looks ok, here is the adjustment procedure for the glass. Click here.
I am about to go offline for the evening, but if you need me, I will be back at 8 am eastern tomorrow.
