What causes a 1993 Chrysler LeBaron to constantly overheat when the AC is running when stopped or stalled in traffic?
It is very common for vehicals to over heat in traffic or sit
still situations because the engine is running at a low RPM and
thus circulating the water slower causing it to hold temperature,
also not much air passes through the radiator at a sit still the
only air moved is by the fan which is not always very reliable. The
AC compresser is not easy to turn and causes the engine to work
hard in order to make the AC work. ==Rad. cooling fan== It may be
that your radiator cooling fan is not working.
