have a multimeter,check alternator output or battery voltage with the climate control diagnostics.key on with engine not running should read about 12 volts,engine running about 13.2-13.6 volts on value #24 in the diagnostic program.
always charge in lieu of a jump when you have a choice.Always use the jump post(in the engine comp) and a good ground ,when you have no other way(away from home).Always charge with the key out of the ignition.
