After successfully ignoring the burning-out of the backlighting of the HomeLink buttons on our '05 XLE for some time, my wife finally managed to punch the #1 button up into the housing one day, so the time for a complete disassembly has arrived. I have two missions:
1) Repair the offending button
2) Replace the burned-out bulbs (Why on earth are they not LEDs, in this day and age? I cannot imagine that LEDs would have cost more.)
A search here of "overhead console" led me to a few postings about both problems, and I see I'm not the only one dealing with the fact that, when pressed often enough, the button will eventually break away from the plastic sprue that it's attached to via two tabs.
As for the bulbs, 4 out of 5 are out, so I'm looking at making a bit of a bulk purchase in that area.
After opening up the console on our dining table, I've got the button temporarily back in position in the housing with the broken tabs back in place, wedged to keep it there with a little piece of cardboard down the side. I have applied two drops of Testor's Liquid Plastic Cement (the really watery-consistency type that comes in a little glass jar with a brush in the cap):
That looks pretty good so far, and after an hour or so of drying, I'm going to give it the treatment again.
Turning to the bulbs, they're little incandescent bulbs on molded-plastic bases, which someone else here said is Toyota part #9001111038. (They're also wrapped with black plastic tape around the sides, so that light can only come out their top end, which I have to say seems unbelievably crude and prone to overheating.)
I haven't checked on availability at the dealer, but they're not unique to Toyota: I recognize them as being very similar to the indicator lights (e.g. Foglamps On) in the dash cluster of my Dad's old '83 BMW 528e. The trick is to find their industry interchange number (e.g. 1157 for brake lamps; 194 for wedge-base marker lamps, etc.), so that I can do a more wide-ranging search to see who's got them for the lowest price. Last time I had to do this, when rebuilding the '83 BMW gauges several years ago, its interchange number turned out to be some really obscure 4- or 5-digit number that not a lot of people stocked, but maybe I'll have better luck this time around.
Think I'll have to put the console back up again as soon as the button is (hopefully) repaired but before the bulbs are replaced, so unfortunately I'm going to have to yank it yet again later on. One tip I can offer on getting it down without breaking it: Remove the two Torx screws at the back end (inside the flip-down mirror housing), drop it down at the back end an inch or so, as far as possible, then work a finger into the gap on each side. Work your fingers forward as much as possible on each side, then use each (one on each side) as a fulcrum or see-saw: push up on the back end of the console to pull the front end downwards, and eventually the (very strong) spring clips will release. Having your fingers in there will help you regulate the pressure you're exerting and avoid breaking anything (including said fingers
