hello my 2004 qx56 right low beam and right fog light are out i check the fuse they work i change the bulb still dont work the high beam ,signal and running light work but not the low beam or the fog light
Check the wire harnes. May be a short or corroded due to water, etc.
There’s a fog lamp rely in the IPDM box in the engine room. Since your other fog is working this should mean the relay is fine, but I i just noting it here for FYI.
