One problem related to brake light on has been reported for the 1999 Ford E-350. The most recently reported issues are listed below.
Ford E-350 and e-250 vans, both are year,1999 the antilock and brake lights came on simultaneously at a 105k miles on each. There should be no reason for this and I also noticed many others with the same issues. It will impose a safety issue because I seen a web site mentioning how to disconnect dash lights for both. Please take this into consideration before auto owners start disconnecting wire harnest. Thanks, tom.
