I was having problems with the fans on my 1996 Formula A4 coming on so I decided to try this mod out. I got the fans to come on, one when the car is off and either one or two when the car is running. What I can't seem to do is keep the led lights on. I will flip the switch on and the lights will light up for a split second and shut off. I have tried it twice and both times I get the same outcome. Can anyone help me out here? I am using the cig lighter for both ground and power.

Maybe you have your LEDs oriented backwards? Since they are diodes, they must be wired with the correct orientation to work.
