AC Controls are not working but clock is still displaying after replacing the bulbs behind the controls... what could be the problem?

In my 2006 Toyota 4Runner the AC controls are not working after I replaced the bulbs behind the knobs. The red security light still flashes, and the clock is still functional... I just can't adjust the temperature and power of the AC system, and the display does not show my miles per gallon or the passenger airbag. What could be the problem? I checked all the fuses and they seem fine.

SOURCE: Replace lighting behind the heater controls

Yeah , something would have broke for real had you pried it any more.
There is a bulb just below the control panel that lights the panel up... and more screws to remove to access it. The ones behind the knobs need to be replaced ( they hold the switches to the face plate), and you need to unscrew the ones behind the trim and above the ash tray.
The trim comes off in one piece (held by clips).

SOURCE: Dash Control Unit Replacement

You can save a LOT of money by fixing it yourself.

All that is wrong with the knob are broken wires from the knob's PC board to the main PC board on the AC control.

All you have to do is remove the AC main control, take it apart, and resolder the broken wires from the PC board with the knob on it, to the main AC pc board. There are 3 wires, any number could be broken.

If you take it apart and solder the broken wires, this WILL fix your issue. Just make sure you put the wires back exactly where they go.

A FIXYA rating (4 blue diamonds) would be most appreciated for my assistance.

SOURCE: my 2003 toyota corlla clock is not displaying, but

Sorry. The clock, the dome light and the radio are on the same circuit. If the radio works, the clock is bad.

SOURCE: also have problem with clock no working.

The clock is easy to remove. I offer a reasonable repair service with a lifetime guerantee.

Clock removal instructions are available here:
http://autoclockrepair.com/vehiclespurchase

1. Place fingers under removable panel and gently lift.
2. It should hinge at the top. Lift until the whole panel
comes off.
3. Then you'll see four clip-in slots where the clock is
being held in place. 2 on top and 2 on bottom (red
arrows). Pull the slots (that are on the panel) away from
the clips (that are on the clock) and push the face of the
clock in so it will pop out through the back. Remove
white power source by holding down the tab and pulling
back.

BOSE RADIO CLOCK/STATION DISPLAY DARK

This problem is caused by two tiny burnt out bulbs behind the LCD display thay are soldered to the circuit board behind the radio LCD display and can be replaced, this requires the radio be removed and the housing taken off and the front display un-clipped, you will need a low temperature solder pencil and thin strand solder the bulbs are available from Radio Shack, the part number is 272-1092, this is a 2 pack of miniature 12 Volt 60Ma bulbs. This radio display bulb is used in may car models, this bulb also repairs climate control displays as well as other low light displays like switches

The dash ac/heat control display lights don't work on my 2006 Ford expedition.

The lights behind the radio controls don't work. Not sure if it is a fuse or light bulb problem.

There is a tiny bulb inside the radio that has burned out, the radio must be removed and the light replaced, this is best left to a radio repair shop as the common practice on new radios is to have the bulb hard wired into the circuit board at the front display.

How do you change the clock's light bulb?

there is no clock light bulb replacement.. you may have a defective radio. The fuse for the radio controls everything. if the radio comes on and the light that your talking about is internal and not coming on then you may need to remove the radio and replace it or repair it.
