Welcome Message from 1A Auto

This new electric push button 4x4 dash mounted switch is a high quality, aftermarket replacement part.

If defective, your truck may not shift into 4WD and your shift light may not indicate 4WD when shifted to 4WD. Why search through junk yards hoping to find a used switch when you can have it brand new!

  • Four selection dash control (2HI, 4HI, 4LO, AUTO 4WD)
    • Fits models with AUTO 4WD Transfer Case - RPO Code "NP8"

  • Built to strict quality control standards

NOTE: If you have any questions about this fitting your application, please call your local GM dealer with the above part numbers.

This electric 4x4 switch makes a good replacement and has good cost savings over the dealer part.
