I'll be giving this a shot again soon... Picked up 4 bulbs from Toyota, P/N 90072-02005, a bit less than $13 after tax. I have an intermittent outage on the left bulb, the right still works but both will be replaced while I have it opened up.
Bought the extra two for spares in case of dropping one. The rear defrost light is out, I'm curious to see what type of bulb is in there - if any luck this will work (anybody know for sure?) I think this is the same bulb in the A/C and recirc switch (though it needs the red condom) which has also been problematic for us on occasion.
Last time I attempted this years ago, the biggest problem was getting some sort of screwdriver back there to push in and turn the bulbs into the HVAC control. I picked up a right angle ratcheting screwdriver from
Harbor Freight (#92630), will see if this helps matters any. Stay tuned.
Wish me luck, this job SUCKS...
