my front blower is doing nothing. no controls other than defrost work and none blow. the center and rear are fine. if theres 1 blower for all im guessing resistor block. if theres more than 1 blower motor im guessing front motor. also note i just changed the actuator after no front a/c controls and severe clicking from under the glovebox. so no clicking now but no controls. tried to reset but maybe i did it wrong. help?
