4.2 AT 1990 - blower ?

My YJ has A/C, so they are two blowers motor (one factory from the airflow (at passenger's side) and the other with air conditioning (at driver's side)) - both until recently did not work. One (at passenger's side) is already running, but it works only when the ventilation switch is set to "heat" but when I switch to "vent" or A / C - the blower motor turns off, and the other does not switch - how they should work - when one works the other does not, or maybe should, or can works together? Both blower motors are ok.

your heater blower is working as it should. the yj ac is a separate system and the blower is controled by the switch on the ac unit.
