I have been told to remove the two screws that are located inside the garage door opener and then to gently pry the cover off. I haven't tried it yet. I am still looking for a more definitive answer also.
There was a posting for a 1999 sienna also with the same problem. In that posting, the answer suggested to use a very thin screw driver to pry the plastic as well.
On my van, the cover seems to be on very tight and it doesn't appear to be much space to insert the screw driver.
If I do end up trying it, I'll let you know the results. I find it hard to believe that we are unable to locate a source for the 'official' method of changing this light.
Good luck If you find out differently email at fyrsquad12002@Yahoo.com. thanks
Thia dome light comes in assembly and more than likely you need to replace it....
Check to be sure the "dome light over ride" switch is not turned on.
Well, how you fix them depends what's wrong with them. Check the fuses and bulbs first.

what cause the ac light to blink on a 1999 Toyota sienna
There is an accordion button on the driver's side door. Look at the very bottom of the Driver's door and to the very right should be a black accordion button but 1 or 2 screws. Sometimes when the screws become loose it will make the dome light not work. Just tighten the screws and it would fix the problem. To test it, just open the passenger door, and if the dome light comes on that would be your problem.
The dome light switch on the dash is on.

The "dome" is the light on the ceiling of your car. It is called a dome because this light is usually shaped like a dome.
My parents have this problem on their 99 Sienna. They got an estimate of an outrageous amount to fix the problem, because it involved disassembling the dash to reach the control for the seatbelt indicator, plus replacing a sensor. They've decided it's not worth it and have learned to ignore the annoying flashing light. Sorry.
