Just as an update to my last post, we did end up buying another DRL module as the old was toast. I say "another" because a "new" one is nearly $300.00 from the dealer only. We found one on Ebay for around $50.00. Yes it's used, but it's been working good since we installed it and we did add a good ground directly to the module, so that should help. You could see on the old module where the some of the components have been heating up, so there is an issue somewhere in these things.
