Oh wow, electrical gremlins... What triggers the switch on the fans to turn them on and off? Where are you getting power from?

 

i installed a manual switch. the fan is hooked up to b+ and the negetive fan side is ran to the switch and a wirecome out of the switch and goes to a good ground.

 

wtf...i moved my truck and now the alarm doesnt go oof but now my door locks dont work. the remote lock doesnt work either.[:@]

 

Take the wiring out and start from scratch. It sounds like you have a nightmare on your hands.

 

I agree with Chris, start over. This shouldn't matter but why do you run the ground to the switch and not the hot.

 

if the switch is on the hot side there will be a small spark every time you want to turn on the fan. but there is no spark on the negitive side. its is for the same reason that you disconnect the negitive side of the battery first then the positive side.
