No start Silverado, Sierra symptoms If you encounter no crank/no start, a weak/dead battery or battery drain condition on the above vehicles and any of the above listed trouble codes, GM recommends you check for water on the rear floor.
Silverado, Sierra water leak
GM has identified a source of water leaks in these vehicles that can cause water to pool on the rear floor which can enter the remote control door lock receiver (RCDLR) and cause corrosion issues. Check the RCDLR module and connector for corrosion. This corrosion can cause the battery drain, no start, no crank condition. The water leak occurs in heavy rain and enters through the center high mounted brake light assembly. The water then flows down through the B or C pillars to pool on the rear floor. The water leak may be visible as a water stain on the headliner.
Fix the water leak
Remove and clean the read high mount stop light assembly.
Then apply Kent Automotive High Tech™ Clear Seam Sealer (P/N P10200 5 oz. tube), or equivalent, to the outer edge of the lamp surface. This product will reseal the lamp assembly when you reinstall it.
Then clean the corrosion from the RCDLR using stabilant and dielectric grease.
