When opening the door the park lights flash in a pattern of around four quick times and then steady on and then back to the blinking. Driving at night the lights turn on and off also making it necessary to use high beam.

O/d flashing indicates a problem in the transmission. It's like a check engine light for the transmission. Count the pattern and Google it. Some will flash just to say help, some will have a pattern. If it has no pattern take to a kragen/oriley pepboys type or a shop to get a scan.
This will be a alerting you to a fault, but to reset the computer to stop the light flashing what you need to do is the following:
Turn the ignition on (till all the lights n the dash come on) just as the airbag light goes off, turn the ignition off quickly and press the door closure button quickly 5 times (the one that alerts you that the drivers door is open) then turn the ignition back on. This should work, but you may need to do it a couple of times.
Alternatively, you can get a diagnostic test done through an auto electrician, that will tell you what the fault is, so that you can get it fixed.
If the cel is flashing, it indicates a misfire, which can quickly ruin your cat converter. If you wish to repair it yourself, have a qualified repair facility diagnose it, tell them up front of your intentions, and pay them for their time. Good luck!
It is possible that your thermostat is stuck open. Normally, the thermostat remains closed when starting cold, confining coolant to the engine block and cylinder head until it heats up. Once the coolant in the block is warm (usually within 10 minutes), the thermostat begins to open and let coolant flow into the radiator to cool it down some. A properly operating thermostat will continue to cycle until the coolant reaches the operating temperature of the thermostat--usually around 180 deg F. Then the thermostat will continue to adjust its opening to maintain that temp.
Thermostats can get stuck in both closed and open positions. When stuck closed, the engine will quickly overheat. When stuck open, the engine will take forever to warm up--especially in cold weather because the coolant is continually pushed into the radiator and cooled off before it ever has a chance to get warm. Changing the inexpensive thermostat may help correct your condition.
Is the flashing steady or is there a pattern to it? If there is a pattern, count the flashes. This will give you error codes relating to the TCU/ECU (Transmission/Electronic Control Unit). If the flashes are steady then it could mean that the TCU itself is bad.
1 long = x10
x shorts = 1 So 1 long and 5 short=15 Please check the light and respond as to whether or not the flashing is steady or not. If not please include the code that is being flashed. Also, include model of the vehicle.
is the dome switch in the correct position it may also indicate a Trouble code is it a steady blink or a few blinks followed by a series of rapid blinks ....try lowering the intensity on the switch for the interior lights it may just be connecting enough to allow it to flash rapidly the door switch may be just opening and closing just enough to cause this an adjustment may be required to fix it does it happen if you hold the door switch in the fully closed position ?
On all doors, it comes on momentarily, then off, as well as switch on dash, leads me to believe there is a circuit breaker in that circuit that's tripping. In some vehicles, they'll use these for power windows, and other circuits for some reason. Have you pulled dome light down & checked that light itself has a good ground going to it, and no bare wire or connector in behind panel that may be rubbing on metal ?
