    Most likely it's the DRL Module, years ago my DRL's were acting up, I replaced the Module and it fixed the problem.

    Disconnect the wiring plug on the driver side fire wall and check for corrosion Volvo has the problem, water will get inside and pins will corrode, before you put it back make sure you fill it with electrical grease
