Two problems related to brake light have been reported for the 1999 Ford F-150. The most recently reported issues are listed below.
The contact owns a 1999 Ford F-150. The contact stated that the brake lights intermittently operated. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 115,000.
Complaint received via e-mail. The turn signals, emergency flashers and the brake lights failed to function. It began as an infrequent problem occurring more and more and lasting longer in duration. I thought the problem only involved the turn signals and emergency flashers. I only found out about the brake light malfunctioned after looking over a wiring diagram of the vehicle. The remedy for the problem, per a car web site, is routed the emergency switch. Depressing the switch numerous times seems to clean the contacts, solving the problem, at least so far.
