2003 Chevrolet Avalanche 2500 Problems

Stalling or Low Engine Idle Speed Due to Dirty Throttle Body

A dirty throttle body may cause a lower than normal idle and possible stalling condition. Performing a throttle body service will commonly correct this concern.

Corrosion on Battery Cable Ends

The battery may leak acid at the battery cable connections. As a result corrosion may form on the battery cable ends. Leaking batteries should be replaced and the cables need to be thoroughly cleaned or replaced if necessary.

ABS Light Due to Poor Electrical Ground Under the Battery Tray

A poor electrical ground under the battery tray may cause the ABS warning light to illuminate. Our technicians tell us that cleaning and properly securing this ground and also the main ABS ground on the frame rail below the drivers door may be necessary.
