While out night wheeling I noticed when sitting in drive with all my aux lights on there is a clicking behind the key/steering wheel area. Sounds like a relay turning on an off erratically. Nothing I can see is turning on or off. Seems to be related to a particular voltage. Turn the a/c blower on and it stops or rev the engine a touch and it stops. If you have the lights on at idle in drive however it will just sit there erratically clicking that relay like it barely has enough voltage to stay engaged. You can feel the thunk of the relay a little in the cover around the turn/wiper levers, but mostly in the key/ignition. Putting your hand on the key you can feel the thunk/click pretty pronounced. What relays could be doing this? Seems maybe the coil is getting weak in one?
