Relay question
I noticed today that one of my relays forward of the radiator support right before the bumper skin on the right to the farthest was clicking on and off very very rappidly. What does this relay do? i unplugged it and didnt seem to effect anything. thanks -alex

Respecognize!
i can check my book for you because there are 5 relays plus two relays. I know the healights are there, i think the electric fan, and i dont remember the rest.
which exact one was clicking? boxy or canish?

Might have a bad headlight switch, backfeeding the dimmer relay, causing the buzzing.
There was another thread on this same subject about 2 weeks ago- see if you can find it...

well the headlights seem to be working fine, its not buzzing inside the cabin, its actually the relay itsself thats rapidly turning on and off that i can hear comming from the relay. I unplugged it, all lights dimmer etc still work. thats why im somewhat confused about this situation. This is the relay thats farthest to the right when looking at the engine bay, correct? thanks -alex

Get your hands on the wiring manual schematic for the headlight switch and headlight relay/dimmer relay circuits, and you'll see what I'm talking about as far as the "backfeeding" goes. There are several diodes internal to the relays and light switch, that when fail, create an alternative electrical circuit that will cause your probs. The trick is going to be figuring out which component is doing it. If you know how to check a diode with a meter, half the battle is already won. Make sure you isolate the relay/ switches (by pulling the plugs) when reading the diodes out...
Either that, or you have some wiring problems (chaffing) in that front harness somewhere...
