    Does the air condtioner relay switch also control the air/heater fan?
    I removed the relay switch this morning and tested it for power
    I am attempting to fix the air/heater fan. It has four prongs one is
    for the power it is getting and when I turn on the switch the second
    has power then a few seconds later I hear a click and the third prong
    now has power. The last prong does not ever light up my power tester,
    I am wondering if this prong is for the air/heater fan and never
    And hopefully this will be an easy fix to just replace the relay
    When I drive the car I can feel a small amount of air at the center
    but it is not cold. This system is R-134a.
    Please help.
