Question about 2004 Chevrolet TrailBlazer
Hi Lisa, I take it that you have the long wheel base version. The clicking you're hearing is an actuator for the HVAC. These can be blown by a disconnected battery. With an intermitent problem like this, check your battery connections, make sure they're good and tight. Gauges going whacko, is probably your ignition switch, or ground. Check the ground on the transmission hump on passenger side. 1 screw to pull the carpet back, it will be right under there. This ground handles a lot of things.

Strange intermittent problems like this can be caused by a faulty ground in the vehicle - I would check all the ground straps for loose or corroded connections. Looking at trouble codes in the vehicle using a code reader may also shed some light on this.

Behind the dash is what they call a constant voltage regulator. It controls the guages. It's small and located behind the dash near speedo.

Did you find out a solution to your problem? I have a 1996 trooper that is showing most of the same symptoms that you have. I'm curious as to your fix. Was it simply a bad ground?

Did you recently replace or disconnect the battery? Common problem is for the airflow actuators to go out and make that clicking sound in the rear when the battery is changed or disconnected.
