Does any one know what l.e.d.'s fit in the 4x4 control switch I only need the size for the indicator light I already changed the main one, its a 00 blazer

 

Check thogerts page I think he has everything listed if not I'm sure he knows and I know he's willing to help.

 

I'm not sure if you can just replace them in the 98+ blazers. I think they are soldered onto the control board.

But if you can remove them by twisting a base off then you need a PC74 bulb.

 

See I told you he would know lol!!

 

Yes they are solderd there are 4 I changed one it lights up the letters the other 3 are the indicators when you switch it to 2hi 4hi n so I just want to know which number are they so I could buy them

 

It should be a PC74.

 

Ok thanks

 

how did you change the one that lights up the letters?

 

Pull out your switch box and open it the there is 4 lights soldered one is bigger than the 3, I forgot the size bulb it uses but they all go soldered remember so do it only if you are comfortable, the smaller lights are for the indicator showing if your t case is in 4hi 4lo or 2hi

 

I bought leds from superbrightleds.com for the bigger 4x4 light that works letters I used a component 5 mm led and the hi and lo leds I used 3mm all have to be soldered and dont forget to wire leds to a resistor also..I learned after wasting several led`s..
The bulbs in the 98+ Blazers for the 4x4 switch and rear wiper switch are all soldered in..
