Rx400H 2008 Mu238 Rear Fog Lamps.

[ColmDub]

Recently had problems with rear fogs not working, Some info which might help others.

Rear fog lights are located in the red fittings on the rear bumper, one on each side.

21 watt, 12 volt.

Feed via a 7.5amp fuse, 6th one down, located in the 4th fuse box, under the glove box, passenger side. This fuse box is not well known.

To access the fuse, pull the black plastic cover directly under the glovebox out and then down.

Release the cable from the courtesy light and remove cover, now with your back on the deck, look up and to the right you will see fuse box.

Lights will only work with dipped headlamps on.

When you turn the stalk switch on it pulls in a relay which if given the ok by the ecu will pull in and feed the 12v to a junction box at rear of car were it splits to both lamps.

My problem was a bad connection drivers side and a wrong connection passenger side.

Note this is a right hand drive car, so for left hand side reverse sides.
