CAdvoc Report post Posted February 8, 2011 2005 American Eagle - Dashboard AC/Heater Control Box ground has blown three times in the last six mos. 3 RV Service Centers have "fixed" the problem, only to have it happen again. Now, I have `another' new control box & will be headed to `another' (the 4th) RV Service Center to 1.) diagnose the cause of the shorting out & 2.) have the new control box installed. Any suggestions, remedies, thoughts to help resolve this issue? Clovis Share this post Link to post Share on other sites
