Back lighting for push button switches on upper left side of dash not working

2010 4WD Double Cab: Noticed on a road trip that my Fog Light, RR Diff Lock, Power Outlet, Instrument light dimmer and power mirror switch back lighting are not working (not sure if the power mirror switch is supposed to light up, but it would be cool if it did).

I saw some other posts about bulb replacement, but all of these switches are in the upper left section of the panel. All other back-lighting on the dash switches / HVAC controls is working. Does anyone know if there might be a common point where an open wire or loose plug could cause this whole section to go out? I figured it was unlikely that all of the back lighting bulbs in this whole section would go at roughly the same time. Wanted to check before I potentially break stuff trying to get switches out of the dash for bulb replacement.

 

I don't think those switches are illuminated.

The inverter illuminates when it is turned on.

 

Those are not illuminated in my 2015, fwiw...

 

Those do light up (unless they have changed since 2007). My switches are in the exact same spot - both (fog, rear locker) were out when I purchased the truck a month ago. Ordered the bulbs and replaced them. Work great now.

 

I have a 2010 sport and there is no back lighting on these

 

2015 OR and mine are dark- unless I turn on the inverter. It always bugged me that the fog lamp button didn't light. My 06 Sport didn't light them up either.

 

The next question is CAN you light them up?

 

I have a lowly SR5 so all I have up there is the foglight switch but it does light up, now, after I pulled it out and replaced the burned out bulb. Here's a link to show how to get to it.

The fog switch isn't illuminated? I know it doesn't light when pushed in but thought it was supposed to be lit.

 

the fog and locker buttons are suppose to light up when your parking lights are flipped to on.

so imo both the bulbs are burnt.
replace them...

 

this ^^^ it illuminates as a background display light not a "indicator" light when locker is engaged.

 

Wow... feeling stupid now- I'm wrong on my 2105- they DO light up. My 06 didn't, but maybe they were simply burnt and I never bothered.

 

All the blue! How'd you get the window blue?

 

Lol. Late edit, how'd you get the window blue?

 

cool thanks.

 

Part # or bulb type for the replacements, anyone?

 

that looks like the same bulb as found behind the heating control unit- correct?

 

...which is a KT928 bulb.

 

I've been told a t4.7 sanded down a bit works for the a/c controls

 

No, I tried that and found the bulb for the heat/AC controls was too big. The one for the foglight switch was about half as big. Yes, it's tiny!
