I'm having the same problem with my 2003 Tahoe. At first it was just the clicking and within a month the dash vents stopped working. Now it only blows through the defrost vents. From what I have read and heard from a couple of mechanics it is a bad a/c mode door actuator. Dealer charges somewhere between $700 and $1,000. I've read that to do it yourself it requires a special tool.
Sounds like the shock is loose, or the shock bushing is worn out.
probably have a bad relay, that was my problem.. Are your turn signals not working, but your hazards lights are? and if so, do you hear a constant clicking sound, like your turn signal is turned on? Does the clicking sound go away when you hit the brakes? It is the relay.
Location of clicking sound not stated but: My 95 S-10, 4.3L engine was clicking when it was running. Turned out to be the fan tapping against the fan shroud, motor mounts were wearing, causing fan to hit this shroud. This may be your problem but you didn't state what area of vehicle sound comes from.
Sounds like you left a retaining clip loose on one of the pull rods.
I actually had this problem with my first xbox. It turned out to be the hard drive.
My Chevy was doing the same thing. It turned out that the connectionc on the starter were getting wet and arching. check that the ceramic shiled is fully intact AND THAT THE WIRES AND CONNECTIONS ARE SECURE TO THE STARTER.
A clicking sound, when trying to start the engine, indicates a dead battery or poor (dirty) battery or starter relay connections.The clicking sound is the starter relay(soleniod) not getting enough power to hold it's contact points together.
The clicking sound is your a/c unit trying to engage. I would have freon pressure checked first, if not, a/c unit may be bad
Most likely the battery is weak and dying. Enough voltage and current to make the solenoid barely engage (clicking in and out), but plenty of current and voltage for the radio and some of the lights.
The horn relay is located in the fuse box under the hood of the 2007 Chevy Tahoe. The horn relay is responsible for making the car horn have sound.
the clicking sound is the blinker. when you signal to turn with your blinker the light flashes and makes a clicking sound.
possibly the timing chain tenisoner. wear on the plastic casuses a clicking sound.
