I hope I can help, I had the same problem on my 2001. I called the dealership and they said 375.00 + parts to fix. Being mechanically inclined I decidet to try it myself. Please understand, this is not exact, but is a pretty good guide. To open from the outside, make sure doors are unlocked(mine relocked after a minute or so) place a screwdriver, long and thin, into the slot that the handle passes through the door on the right side. Raise the handle of the driver, and you should be pressing down on a cable that operates the latch. the door should release. If you cant do that, from the inside, remove the two side trim pieces. Then remove the inner door panel, One screw under plastic cap on handle, one under cap on strap... and pop off all plastic buttons(hidden) between the door and cover, a 1" putty knife will work for this. You will see the cable that used to connect to the handle. Remove the cable by pulling it through the slot(apparent when you get to it) and now remove the two screws that hold the handle on. Also, you have to remove a screw from the passengers side of the cover plate over the handle. the plate will slide(not sure which way now), and it will come off. replace the handle and etc..... inreverse.. Took me 25 minutes, start to finish. Further questions, let me know. remember, mine was 2001 Sienna.

DRL's can be added simply by adding a 20 amp fuse into an empty slot in the fuse box.

SOURCE: The sliding door handles of my 1998 Toyota Sienna have both broken.

I replaced both of my sliding door handles this weekend. It was actually pretty easy. Cheapest I could find the handles was a little over $70 each. The interior panel is held on with one screw and 10 nylon clips. The one screw is in the cup holder. Put you hand in the cup holder and push out at the bottom. It pops right off exposing the one screw. I started on the clips from the top at a corner. Seemed to be the easiest place to slide a screw driver under. Once I got the screw driver in, I started working my fingers under the panel. The clips run mostly along the top and bottom about 6 inches from the edge. I made an effort to apply the force as close to the clips as I could to reduce flexing the panel. Once I got the first clip to pop out the other followed pretty easy and the panel lifted right off. Carefully peel back the plastic barrier. The exterior handle is held on with two 10mm bolts. Connecting the short cable was pretty obvious once you could see everything. Now I have to teach everyone to open the side doors very gently! Hope this helps.
