Question 2003 36D Bounder: behind circuit breaker panel, clicking noise lasts for a minute then stops.

[Jim Levick]

Replacing the Auto Xfer Switch a year ago did not stop the clicking. Appears clicking coming from a small black box with 12V wire connectors. What is is part's name and function??

if its like my '96 bounder the black box would be the control box for hvac system. ECC or ECM

Did your black box click often? Where you able to correct the problem?

Following. We are currently experiencing this same problem with our 98 fleetwood vision. The black box (HVAC) clicks every 5 seconds and a small red light blinks with every click. The lights throughout dim when it clicks also. Our front slider will not go out all of a sudden either. Help!

While I am not familiar with your unit here is my thought. in my Coach there are also relays behind the breaker panel which are used when specific loads turn on. There is a audible click when theses energize.
