I have a 97 F-150 Lariat 2wd that has started to have some strange electrical problems. The first thing that started was the power door lock does not work on the drivers side. I thought this could be a problem with just the lock mechanism itself but now I am not sure. Now my auto-headlamps will not turn on, and just the other day I got in to go and none of the gages work. Speedo, odometer, tach, etc. The fuses are all good so I need to know if anyone has any idea what the problem could be. I want to avoid taking to a dealer if possible since it is out of warranty. Thanks in advance.
