2002 Explorer Electrical Problems

I've got a 2002 Eddie Bauer Explorer that is beginning to have weird intermittant electrical problems:
1. The interior light fails to come on when the door is opened occasionally.
2. When putting the key into the switch, the seat stays all the way back and doesn't go to the memory preset position and you have to press the appropriate button. It also seems to lose the memory at times and then you have to start over. This is happening more and more.
3. The cruise control has gotten screwy. After turning it on, it won't engage when the press the Set/+ toggle. You have to press the Coast/- toggle for it to engage. Also, quickly pressing the Set/+ button after getting it to engage doesn't allow you to increase the speed in increments as it should. To change the speed, you have to turn it off and then back on and set with the Coast/- toggle.
4. Lastly, the compass has gotten confused and always display the direction as southeast or southwest regardless of your aiming straight north.
Has anyone else had problems like these and how did you go about correcting it? Any help or comments would be greatly appreciated!

1. Is your door switch sticking ? does it act the same on all doors?
2. Memory seats I'm not familiar with. Looking at diagram for a 98, the obvious possible causes are sticking mem or set button, memory module itself, or possibly wrong set procedues being used?
3. Here is the diagnostic routine for a 1999: Should be enough to fix it unless
you have a more involved problem
Extracting and Clearing Codes (Self-Test Diagnostics)
WARNING: THIS TEST IS A KEY ON ENGINE OFF (KOEO) TEST ONLY THAT IS CONDUCTED
IN PARK ONLY WITH EMERGENCY BRAKE FULLY ENGAGED.
Enter Self-Test Diagnostics by depressing the speed control OFF switch while
turning the ignition key ON, ensuring engine does not start and is not
running. The speed control indicator lamp on the instrument panel will flash
once to indicate that the speed control module entered the diagnostic mode.
NOTE: Five additional flashes at this point indicate a defective speed
control servo.
Release the OFF switch.
Press the remaining switches in this sequence: ON, RSM (resume), CST (coast),
and SET/ACCEL. The speed control indicator lamp will flash as each switch is
pressed. Press each switch in the sequence immediately after the light goes
out for the previous switch.
NOTE: If the ON switch is not pressed within 5 seconds after entering the
diagnostic mode, the module times out and the procedure must be started over.
A lamp flash with the last button (SET/ACCEL) indicates that the STATIC test
passed. If the lamp does not flash with the last button and there are no
additional flashes of the lamp, the switch is defective. If the lamp does not
flash with the last button, and additional flashes occur, follow the chart
below for trouble codes:
2 flashes - Brake Pedal Position (BPP) switch is defective, circuit is
defective, or brake pedal is applied; Clutch Pedal Position (CPP) switch is
defective, circuit is defective, or clutch pedal is applied.
3 flashes - Brake deactivation switch is open or circuit is defective.
4 flashes - Vehicle speed signal is out of range or circuit is defective.
Immediately after the static test has passed, the speed servo will then
perform a dynamic test automatically by actuating the throttle lever from 1
mm to 10 mm of travel from the idle position. During the dynamic throttle
pull, observe the throttle movement to witness any binding or sticking of
actuator cable, proper connection of actuator cable to throttle lever, and
ensure throttle returns back to idle position. If improper connection and/or
binding or sticking of actuator is observed, go to Symptom Chart. See:
Symptom Chart
Return ignition switch to the OFF position and proceed to Symptom Chart. See:
Symptom Chart
4. Your compass sounds like it needs to be calibrated. You need to put it in "CAL" mode and drive ina circle in a certain direction at 5 mph or so until it finds itself. Check your owners manual. The procedure should be in there. If not search the forum for compass and you should find it.
