Hey folks,
I was replacing my head unit the other day and thought I'd try to find out why my HVAC controls don't light up when I turn my lights on. Turns out there's a little bulb in the middle of the four sliders (fan speed, temp, fresh/recirc, and registers).

It's a tiny bulb, maybe a half inch long and it's got a green 'condom' on it. To make it glow green. Anyways, I'm having a heck of a time trying to find a replacement for this sucker. Has anyone replaced this bulb before? If so, where did you find a replacement?

thanks!

 

Local auto parts store, and the dealer should have it too.

It sure took me awhile a long long time ago to figure out how to access it, but most know how to get to the bulb now.

 

thanks,
the stealership seemed clueless

 

A bit of a hijack, but what would cause the bulb to only work when its cold out? Unless its below -10 degrees celsuis, that light will not come on. Otherwise it does. Its the weirdest thing... End hijack

 

dont worry, a couple more months and you wont have to worry about cold weather any more!! golfing in january, flowers up in february, bbq's into december, ahh, the joys of living on the west coast.

how about the tinny ass bulb in the AC switch that lights up the button when its on?

 

My bulb is still good,
but every now and then you have to bang the dash to get it to light up,
well that was after the first stereo install,
then I installed the CB and some how fried that one,
So I got another one,
now the bulb is good but every now and then when you move the controls it flickers....

So yeah...

 

exact same thing always happened on my 93 runner and on my sister's 94 corolla - weird!

 

i had that same problem only saw the light come on 1time
found a bad wire just tap in at the lighter with some new lights and now i have light back there when when i turn the lights on

 

Yeah, been there. Dealer wanted to replace whole switch to fix bulb. Never did find a bulb for that one. Got a donor from boneyard, switch and all for $5.

 

i have to tap my dash to get mine to go on for the one behind the fan speed slider

 

its a 192 bulb got a 2 pack from autozone for 2.99 infact i still have a unused one need it???

 

I think thats the same one for the tail lights/blinker isn't it? minues the green cover? can you reuse hte green cover?

 

I think there is a flaw with the socket design or something because all of the trucks seem to have the flicker issue at one time or another. Once I figured out where the bulb was I found out I could just firmly push right on top of it and most of the time it would come back on.

Mine did burn out a few years ago and the aftermarket bulb was a little thicker at the base and kind of stretched out the prongs in the socket. I was able to get it in there and it works, but I doubt I could run an oem bulb again now that it has been stretched.

 

Well, I picked up the OEM bulb form the stealership this morning.

In case anyone cares, here's the Toyota part no.: 90981-11014

It cost me $2.68!! :eek: But, that's one less thing to annoy me

 

I have the same issue with my 97 4Runner (3rd Gen) the HVAC backlight (Toyota OEM 90981-11014) is failing. I will try the GE 192 bulb, hope that helps.

 

i changed mine with the bulb from autozone the reason it flickers is a bad connection at the base now if i could get my ac to work.
