Well before I run out and replace the vent solenoid. I was hoping yall could give me a little advice on how the circuit works so I can rule out the wiring. I have tested the wires and with the key on(truck not running) I have 12V at the yellow(ish) wire (color blind so please go easy on me) now the white(ish) wire is a ground. I have no tech2 so I can't cycle the solenoid and test the wires to see if all's good. Can someone tell me how this circuit works so I can go buy the solenoid can get rid of this light? It is driving me nuts. If it is a normally closed circuit then I can assume that my wires are ok, but if it is supposed to be open and the + or - cycles the solenoid, I am in deep
Thanks,
Richard
