Question about 2001 Kia Rio
Daytime running light module failure...pkl triggerred through it.
Posted on Aug 26, 2008
Found this on a Kia forum. Sounds like it could be useful here.
"OK my dash and marker lights were out because the DRL module had failed.
I bet this is a fairly common problem so...before you go spending big bucks on a new one or even a few on a used one, why not see if the one you have is salvageable?
The Daytime Running Light module is located with other modules on a plate bolted to the driver's side kick panel. It's the biggest, black one and has DRL Module labeled right on it.
Because this is the module that produces the most heat and therefore is the most likely to fail, the motherless dogs who designed the 2002 Rio put it on the left side of the plate so that you have to move a harness and unbolt the plate to get at it. If you've got big shoulders and arms, getting the plate off is going to hurt. If you're left-handed, you're screwed.
Once you've got the module out and have had your crushed ribs bandaged, which were crushed while laying over the door sill to get under the dash, you pop off the module cover and check the solder side of the circuit board for bad solder joints around the main relay connections (that's the big white block on the board).
They run a fair amount of wattage through the relay, so it gets hot when it's on and cools when it shuts down. Over time this crystallizes the solder and forms a circular crack around the connection that gets bigger until it's essentially no longer connected to the circuit board and all your dash and marker lights go dark.
The motherless dog who designed the circuit could have avoided this by using a relay with a higher wattage rating (which would be bigger, making the module larger, but would run a lot cooler), but then we wouldn't have an expensive, consumable part to have replaced by the dealership would we.
Anyway, check the module for any burned components. If everything else looks OK, re-solder the connections (or have a friend who really knows how to properly solder electronic circuits do it otherwise you'll just finish what inadequate design started), pop the module back together, plug it in, test the lights and if working, reinstall it and the mounting plate - and for the love of God put a thick pillow on the door sill this time to protect your bruised ribs.
Hope this proves helpful. It's actually a real easy fix."

# 3 solution is right on. I took the part off and opened to find bad solder joint. re solder and problem solved. thank you so much. I never would have thought the DRL, when it seemed they were about the only thing that was actually working.
