My father in law has a 2007 F150 XT and all the lights on the dash are flashing. They flash everything from ABS to cel and the speedo flickers on and off. Any ideas what is causing this?? Truck runs fine (drove it to the local gas station), just flickering dash lights.

Thanks in advance!!

 

May be the cluster. You can try disconnecting the battery cable for a few seconds, then reconnect. Sometimes this resets the cluster. Some have had success with this. Others have also tried to remove then reconnect the two wire harnesses that connect to the cluster (you have to remove the lower cover (below steering wheel) to get to the two screws that hold the upper dash cluster cover to gain access to these two cluster wire harness.

If that does not work, and your battery is in good health, then the cluster is the culprit. Locate one off of Ebay from your model, have the mileage flashed to match your current cluster. If you buy one (cluster) from Ford, it will be three times the cost.
