Jeep Repair: 2002 Jeep Liberty, jeep liberty, commutation

Question
There is a red LED that is illuminated on the dash just left and bellow the RPM indicator.  There is no label for this light at all and it is not in the owners manual.  When this light came on, the A/C quit working as did the headlights, and power door locks.  The overhead console computer is receiving power but shows dashes --- for all readings.  Any idea what could be causing this???  Thanks

Answer
the red dot is for the SKIM system the chip in the key.
The other stuff is more then likely all related like a loss of commutation in the whole system  U will need to have some one take a look at this that has scanners and can see what computers are down and so on. A dealer will ave this ability.
