DRL help

[woody367]

I have have a 99 Yukon, the daytime running lights do not work and I would like them fixed. I figure the problem to be what I think is a diode. It is mounted under the dash and has a metal finned housing. I am not sure what it is called, what part# it is or if I can get it other then the dealer, can anyone help. I have attached a photo. Thanks

that looks like the resistor for the blower motor.

I found it at Advance ayto parts, it is called a DRL module. All fixed, thanks.
