billccm Posted January 25, 2023 Share Posted January 25, 2023 Hello: My daughter just moved away from home and called tonight that her 2007 Fusion turn signals went into 'hyperflash'. Owning many Fords I know this is a sign that the bulb is out, but what I don't understand is BOTH sides? She confirmed that both left and right rear turn signals do not flash. The dash warning for left says "Check Left Bulb" and the dash warning for right says "Check All Bulbs". Sounds like a common ground issue to me? Anyhow, her being in a new town and me being away not sure how I am going to troubleshoot this issue, much less resolve it. Any advice is appreciated. Take care, and Happy New Year!

billccm Posted January 27, 2023 Author Share Posted January 27, 2023 Not sure there is anyone out there listening, but thought I'd update in case anyone ever searches for this same symptom. ALL Bulbs in the stop circuit were bad, including the third high mounted light! I cleaned the sockets with DeOxIt, replaced the bulbs, and restored operation. Stop, hazard, and Turn Signals functioned, BUT the 'check left bulb' error came up whenever the Turn Signals were on. So, I disconnected the battery, shorted negative cable to positive. Reconnected the battery and all is well now! Good Luck and Take Care! 0 Quote Link to comment Share on other sites More sharing options...

Just so you know...There are always people out here listening. However, sometimes there is no good advice other than for us to get our hands dirty and try to diagnose/fix it ourselves (if able to), or take it to a Dealer/shop to have it fixed. Luckily, you are one of the people who can diagnose and fix something yourself. Thanks for the update, as it may help others in the future. Good luck! 0 Quote Link to comment Share on other sites More sharing options...
