On the instrument cluster, the center cluster back lights are out What would cause all the lights to burn out? Are they LEDs or bulbs? I would assume that there should be many led/bulbs on the PCB and maybe one, but not all go bad?
they are in series, so if one goes, they all go! they are SMD LEDs, 1210 or PLCC-2 to be exact. see my sig for a link to purchase new ones if you are going to replace them. they are soldered to the PC board, FYI. Let me know if you need any help.
for ease of reference and ordering, here is the required amount of LEDs for each aspect of the cluster:
- Background = 11
- Needles = 7
- Turn Signals = 2 per side
- Additional indicators (ie CEL, Batt, Cruise etc..) = 1 per light
Obviously id buy much more than the minimums.
Just to verify...when you say 1210 or PLCC-2, 1210 is the LED size and the PLCC-2 is the surface mount foot print?
the LEDs are known as 1210 and also as PLCC-2. just giving you info.
the rundown is not accurate for the 4runners!! those qtys are good only for the tacomas (where i came from!). the qty for the 4runners very depending on your year and model.
i am still building my reference, but it appears your 06 SR5 uses the following:
