Default 2007 body control module repair

I have figured out that my leaking sun roof has shorted out something in my body control module. So far the only sign i see is that my flashers wont shut off. Does anyone know where i can send this to for repair? Even if i buy a good one from another H3 i would have to have it reprogrammed to my vin anyway so i may as well sent this one out for repair. Has anyone sent their module out to anyone that is reliable?

Run a search here and READ up on what needs to be done. Yes you will need programming, and not just any fly by night web seller can do it.

Here is some reading: programming an H3 speedometer reset as preliminary for BCM transplant

BCM Nightmare

Meanwhile. do the Sunroof Drain Fix, there is s Sticky Thread on that here top of the H3 section.
