Thought I'd post this in case anyone had the same problem. First the fuel door wouldn't stay closed. The plastic was worn on the latch where the piece from the cable release rubs. I just filled the worn spot with some cold weld and it's now works fine.
The other was more difficult. The passenger power lock wouldn't work. The signals all checked out but the motor wouldn't turn. Took it apart to have a look. There is a thermistor in line with the motor. It was open when I checked it with my meter. So I unsoldered it and put 12 vdc to the motor. It worked fine. Then I recheked the thermistor and it checked fine. Soldered it back in and everything worked fine. Must have been a cold solder joint. Not a quick fix, but cheap!
