The DDM had burnt out. I took the DDM out and it was melted. So called dealer. They wanted all most 300 dollars. I said have a nice day. Ebay 65 dollars. (great deal) Anyways, i got the part hooked it up and nothing! Didnt know what else to do.. so i left it hooked up. Went back to it 45 min later to check my connections and relized the DDM has burnt out again. Could not beleive it. I checked all fuses, OK. So, its getting power to the DDM but it's getting so hot and just burns/melts my DDM. Im lost for words now. Any suggestions anyone

Did you analyze why the first one burnt up? Trace the bad wiring or look for the burn marks? Ones that get excessively wet are the ones at risk for dying, as you probably know.

Do you have a meter and want to trace the input connectors and see if they're all proper? Any electrical troubleshooting background? Can you take pics of the dead module(s) and help us understand where your problem is likely to be so we can infer a root cause?
