sd92129 Posted February 12, 2009 Share Posted February 12, 2009 Just wanted to share this with the community and potentially help someone save a couple hundred bucks. Sorry there are no pictures. I was having problems with my drl's, more specifically, they were not working. The vehicle is a canadian 1998 SE. The regular light were fine as were the high beams. Instead of dropping 200 on a new module (or there abouts), I pulled the module out. On the 1998, it is a 3"X2"X1" black plastic box located in the engine compartment on the passenger side wheel well hidden by the battery. So removal of the battery and disconnecting the 2 wire harnesses and one bolt allows removal of the module. The module can be disassembled, but a fair amount of force is required. the wire harness end pulls out of the plastic cover revealing a circuit board. In my case, one of the 2 larger components (presumably relays) had a questionable solder arguably caused by significant electrical currents, heat and age. Anyways, I resoldered that connection, popped the unit back together and reinstalled. Et voila, drls were fine again. So, in summary, if you are handy enough to do the above, this could be a possible solution if you daytime running lights are not working. Note, with the module removed, you will have no lights. So it is possible, other headlight issues could be caused by a faulty circuit in the drl module. Link to comment Share on other sites More sharing options...
tekazgtr1984 Posted February 13, 2009 Share Posted February 13, 2009 That connection is supposedly the fail on most early model R50's, mine's no exception. In cold weather, no DRL's; I got 'em when it's -10C or higher. I'm guessing the only real long-term solution is to resolder it yourself and hope for the best.

morpheus Posted February 13, 2009 Share Posted February 13, 2009 We resolder them all the time, and very rarely have we had one that came back and needed a replacement after. Link to comment Share on other sites More sharing options...
adamzan Posted February 13, 2009 Share Posted February 13, 2009 Just wondering, but is the wd21 DRL module the same? And would it failing cause my DRL to be my highbeams at full power. I got pulled over and warned 2 days ago Link to comment Share on other sites More sharing options...
morpheus Posted February 13, 2009 Share Posted February 13, 2009 All Nissan DTRL modules work on the same principal. Ususally a bad DRL module will make 1 headlight appear burnt out, not both on high beam. Link to comment Share on other sites More sharing options...
adamzan Posted February 13, 2009 Share Posted February 13, 2009 (edited) I found a wire that goes across from one headlight to the other that didn't look factory, I cut it to see what happened and the drivers side drl went out. Someones cheap ass fix is going to cost me one of these days! It's funny these drl highbeams are actually brighter than my regular high beams.

morpheus Posted February 13, 2009 Share Posted February 13, 2009 Sounds like someone has tried to fix it previously. Get rid of the extra wire, solder the drl and you might just be fine. Link to comment Share on other sites More sharing options...
