Review on ACDelco 88983914 Original Equipment Differential by Marco Cervantes

Revainrating 5 out of 5

Fixed brake warning indicator. Also fits older models.

I installed this on a 2004 Silverado to fix the brake warning light. This is the same switch found on the $100 combo/proportional valve (21998450) that GM plans to replace if only the switch fails. Changes in 10 min. No need to flush the system. Should work well on 2000 thru 2006 Silverados, Tahoes, Suburbans and other vehicles with the same combination valve.

Pros
  • Great for a small home
Cons
  • Fits
