    a/c and blower
    I have a Lennox Furnace, these are the numbers on my unit: CR19-31-2FF & G12RQ3E-82-14. My problem is that the a/c and blower will not come on. I know there is a fan limit switch, which works with the heat. My question is, does the fan relay control the a/c as well. I am not getting the 24v to the a/c contactor, but do have 24v on the thermostat. The blue wire is the one that controls the a/c contactor. I can by pass by jumping from the red to the blue and the a/c starts but not the blower. The blower works if I turn the switch on thermostat to on, just not on auto. Any help would be greatly apreciated. Thanking you in advance! Right now I don't feel too Hande. Lol
