No I do not want to just replace parts. Lets put you digital multi meter to work and do a couple of tests to make sure weather or not that is the problem ok. Now under the hood on the radiator support on the right (passanger) side there is a relay. This is the daytime running light relay. Let test this first. You need to check the power in this will be the red and white wire, this should be constant power if I am reading right. The red and black wire should be power when the key is on. If that is not true then it maybe the other way around the wiring diagram is not totally clear. Now your red and blue wire is power out. So if both the red and white as well as the red and black wire have power all the time then we need to look into the DRL Module. But if only one has power when the key is off but yet the red and blue wire is still sending power then we will need to unplug this relay and see if the light then turn off. If so then we will do a ohms test on the relay. This is a 4 term relay.
The ohms test will go as follows. So set you meter to ohms and check for continuity between term 1 (this is the where the red and blue wire connects to it) and term 3 (red and black wire). Then between term 1 and term 4 (red and white wire). If there is continuity between any of those then the relay has stuck closed and needs to be replaced. Get back to me and we check the DRL module next if that test good.
