auto 4x4 selector switch and recirc switch

[w140amg]

Has anyone replaced these bulbs?

auto 4x4 selector switch. Do not light up at night: 2H and Auto side. 4H 4L light up.
recirc switch (next to A/C switch)

Any info is appreciated.
Thanks!

I would like to know this information too! What is the bulb type for the A/C and recirc buttons? On my tahoe, they are both burned.

I believe, for the 4 HiLo switch, you will have to remove the switch, the unsolder a bunch of pins just to open it to replace the bulbs. It's a real pain, but possible.
