Download Retractable Running Board Deployment Concerns ’04 Lincoln – Some 2003-2004 Lincoln Navigator retractable running boards may exhibit false reversal, partial deployment or retraction and/or jerky/noisy operation. This may be due to mechanical binding or damage to running board deployment mechanisms. ACTION Verify there are no hidden debris in the running board tracks that may cause the condition. Clean the running board tracks with a high pressure washer if available and test the system again. If the condition is not corrected follow normal Workshop Manual diagnostics. If the condition continues refer to the Service Procedure for component testing and replacement.
