interior noise behind dash
Sebring 2007 V6 sedan 50k km .
Large, loud clicking noise, irregular, comes from behind dash or ignition key...can't exactly tell ..
no MIL , no codes on OBDII everything works perfectly
any ideas before I start disassembling ?

well it lasts about 3-4 seconds before it stops. and on OBDII no DTC was recorded a nothing came up when running HVAC test.
I can replace the actuator but I have no idea how to calibrate it, or there could be damaged control unit that is pushing the actuator too far ?

I'm measuring voltage range +5.0 to - 5.0 V when rotating temp control knop is this voltage correct ?
should it be 0V on COLD end or HOT end when door is totally closed to evaporator or opposite to heater core ?
pls advise. i'm getting crazy here ..!

What are you using to read the HVAC, a DRB or a generic? Try doing a capacitive discharge (unhooking and touching battery terminals together for 10-30 minutes) and when you boot back up it should go through self calibration when you start the car. I'm assuming you have Auto temp control ATC since you have the V-6 in it.

Normal scan tool, it shows DTC if generated by HVAC without ability to calibrate actuators. and I used voltimeter to measure the voltage at actuator motor. I thought that voltage when blend door is closed to max cool or max heat should be zero.
Tomorrow i will get new actuator ( 62$ from mopar ) replace and perform capacitive discharge as you suggested.
and yes I do have ATC.
