Default 4wd service light
In my 00 GMC Sirra the 4wd service light came on. What do I do about it?

Thanks

I was told it was a front axle acuator(sp). Around $230 w/ labor. I can't find my hptuner cable (brother hid it) so I can't read my codes just yet. Will get it cleared up tomorrow.

Thanks

This happened to me once, and it was just the switch in the dash. As said before, you really just need to read the trouble code to know exactly what it is.

I Have had the same thing, several places I looked all said probably the switch, so if you don't have any codes look into a switch...

Mine was doing that. I took the switch out, and popped the switch housing apart. I could see the solder on the backs of the switches was broken, so I just re-soldered them. Ta-da! Like new.

Cool beans! But does anyone know how much a new switch would be?
