Under dash, driver side, near fuse block, clicking sound
As the title states I am getting a clicking sound, sounds like a relay or something clicking, it clicks about every 10 seconds or so anytime the key is in the run position, engine running or not. It is on the driver side, under the dash, somewhere around the fuse block. I cannot for the life of me figure out what it is. I have held onto everything I can get my hands on in that area and wait for the sound to see if I can feel it to let me know where exactly it is coming from, but nothing.

Never had this before. Parked it a few days ago, removed instrument cluster (which involved unplugging the rear hatch button and cluster of course), installed a reverse glow gauge face from Speedhut, reconnected the cluster after wiring the inverter for the gauge face to my headlight switch, and then turned key to run position to test things out. This is when the clicking sound started. I thought maybe it had something to do with the rear hatch switch still being disconnected. I now have all my needles re-calibrated, the instrument cluster completely re-installed, and the rear hatch switch re-connected. Everything is back together, I still have the clicking sound when the key is in the Run position.

Anyone have any idea what this could be? It's driving me crazy.

check your connection to the headlight switch for the gauges, other than that i am cant think of anything else, the only time i ever heard a clicking noise in my car is when the alternator went out, 3 times in 4 years

I found this, Alternator Clip "How-To", but it looks as if half of his post is missing now so I have no idea of what to even look for.

I don't have any of those other issues though and my voltage is perfectly fine. Alternator seems to be working just fine, no noises from the alternator itself and no problems with any lights whatsoever. Just the clicking sound they mention in that thread.

Found the problem. Back when I first got the car I removed the fuse for the rear wiper since I never plan on using it and both wipers are on the same switch. So I removed the fuse so i'd never accidentally turn it on (seen too many rear windows get scratched from wipers). I guess I must have bumped the switch backward during the process of removing the cluster, which of course that makes it control the rear wiper. So, I still don't know what the heck is doing all of that clicking, but with the switch pushed forward for controlling the front wipers the clicking is gone. Move the switch backward and the clicking resumes. All that crap I went through trying to figure out the problem and it was as simple as moving the switch forward.

I just had this exact problem with mine. So before you blow it up, try this. Clean off your battery! It could just be corroded.

My car used to have that clicking noise. My lights would flicker, the engine would stall, and that damn clicking there anything more annoying than that?

So yeah just clean off your battery terminals. Disconnect them first, then get a toothbrush and mix some warm water and baking soda. Pour a little bit of it on the terminals, watch the corrosion start to bubble, and start scrubbing it with the toothbrush. After you give both terminals a good scrubbing, it might not be a bad idea to change out the nuts holding the terminals to the battery.

Hope that helps!

Cuz i did look at it some more and it looks like there is some melting of the plastic going futher down.. i did try to clean it off today and it a pain in the butt.. gauges started to bounce and clicking noise in rythem with gauges while starting.

Bad ground!!!
I have my 2004 2.3L SE die on me in Georgia while driving to FL. It had been making a clicking noise coming from under the dash randomly while driving.
I had it diagnosed several times, all of which were useless.
I replaced the battery and alternator at the same time when it die in GA and it started making the sound again once I got back to good ole MI! I FINALLY got smart and replaced the grounds and that solved the problem.
I highly suggest once you have checked fuses and connections to just replace your grounds. Its simple, easy and cheap to do.
