My H3 was waiting for a new Motor and the sun roof started leaking and completely ruined the interior. I'm concerned about mold behind the dash board and about residual odors if I were to try and restore it. Does anyone have any experience with this...or suggestions?

 

Before mold remediation can begin, any sources of water or moisture must be addressed.

 

Agree find out and remedy problem. Then follow SOP for drying and refreshing interior. Its standard...

 

Google how to fix H3 hummer leaking sunroof. Same procedure for many vehicles give or take, clean out the sunroof drains, modify the tube ends by cutting out the X, then dry out. Pull the vehicle inside, pull out carper and insulation, blow warm dry air at it. Do not put back together until completely dry.

Hope you did not toast the BCM when you failed to address the sunroof leak. Usually the problem, odor and mold............ not so much
