On my 2006 H3 lately a clicking sound under dash/ behind radio on start up. Click,click,click,click and then it stops. anyone with this issue?

 

Probably the A/C-Heater control actuator motor. Crawl under the dash and look up (driver side); there are two actuator motors that control blend doors for the HVAC system. You can watch/feel them to see which one is acting up.
