it sounds like the battery ??? if it goes with a jump, then it points to a weak battery anyway....
when engines running , alternator is keeping things going---so when you try to work more electrical items----it throws a wobbler.....
so first of all check battery voltage with multimeter to see whats in it
get it running; use multi-meter across battery to check voltage again and keep it connected for next step.
put all lights on, heater blower,hazards ,hrw.........see what the multimeter says now...
it should dip down as you use more power, so rev the engine and you should see voltage go up to about13.0---14.0 volts...
if it does rise---the alternators ok
if it doesnt move the alternators gone
