The contact owns a 2003 Ford F-150. The contact stated that while making a right turn, the turn signal would not activate until the steering wheel was raised into a higher position.

The manufacturer was made aware of the failure and stated there were no related recalls. The failure mileage was 145,000.
The multi-function switch on my 2003 Ford F-150 harley davidson is faulty. It fails intermittently causing the left turn signal to not function at all. It affects the hazard flashers as well. It works only intermittently and then fails again. I have had no accidents and the vehicle had only about 48,000 miles when the failure started. I have almost been rear-ended several times due to the left turn signal failing.
