Hi. I have a 2011 Odyssey EXL, 160k miles. Well maintained. My passenger side DRL and high beam is dead (same bulb). I've replaced the bulb and no luck. All fuses are good. Volt meter shows good voltage, but when the DRL or high beam is activated the voltage drops to 0. All the other accessories in the vehicle are working normally (including the driver side DRL and high beam). On older 2010 models there is a DRL voltage modulator, but it appears the 2011 does not have this. If it does, it is not behind the glove box nor steering wheel and a parts search shows no replacement part for this. I'm stumped. How can the harness have normal voltage then drop to 0 when the light is turned on... The alternator seems completely normal. Any help would be appreciated. I have not seen this addressed on forums or technical bulletins. Thanks.
