Replaced both headlights. Driver's side is fine. Passenger side does not work. I can hear a clicking noise in relay/fuse box under hood which is located near the headlight. Did relay blow out during replacement? Which relay? There are 4 relays I believe.

do not use WD40 it is not a lubricant.

It could be a number of things ...

1. Headlight switch could have gone bad
2. Headlight grounding could have gone bad
3. Relay/fuse could have gone bad

For this model year the headlamp relay/fuses are in the relay box under the hood (not in the passenger compartment) ... usually mounted on the left driver side (USA models) under the hood above the wheel well
Good luck on your troubleshooting.
Helpful?

Thank you I had the same problem. My connector was also loose on my 2012 Focus. It was on the passenger side beneath the headlights. I reached through a loose splash guard and pushed it back in and whala.

From Info I have looked at I believe under hood micro switch relay 35 is for low beam and 34 is for high beam. It also looks like you have a different fuse for each light. The relay are for both low beam or both high beams. each headlight has its own fuse. I believe #4 fuse under hood is for passenger side low beam. fuses 1-4 under hood are for the four headlights as I understand the info I have seen.

My 2011 Traverse had no LOW BEAMS ( Right and Left Side )
I changed the LOW BEAM RELAY ( a 4 prong relay ) in the fuse / relay box located under the hood on the passenger side. It didn't change the situation. Voltage was good at the relay terminals and I plugged the relay into another GM car and it worked fine. The NEXT place the voltage goes to is the LOW BEAM HEADLIGHTS. The easier way to change them on a 2011 Traverse is to go through each wheel well - there is an access port behind the wheel well liner. YouTube has photos and videos on how to take this apart. Don't try to attack the problem from above in the engine compartment, the wheel well is the easier ( notice I said easier not easy ) way to go about it. BOTH of my Low Beam headlamps driver side and passenger side were burned out. I just bought the vehicle ( yeah...I know...who doesn't check the lights before buying a vehicle - right ? ) and at my wits end figured that it is such a pain in the rear to change the bulbs, that the lazy bastards that owned the vehicle just drove with one headlight and THEN the second one went out. If you can hear your low beam relay clicking ( you can feel it too if someone turns the headlights on with the key in the ignition turned to ON ) and you're getting 12 volts or higher at the relay terminals in both places ( the relay coil power and relay output terminals ) then the only thing next is the bulbs themselves. Thank God for small miracles. NOBODY likes an electrical / electronics problem.

Hi, if the light on the switch is coming on, the relay is fine. Unless both bulbs are burned out, the problem is in the wiring between the relay and the lights. I recommend you trace the wiring backward from the passenger side fog light to the power box under the hood to see if the wire is cut. There should be two wires coming out of the power box--one going to each fog light. If the wiring looks good, it is also possible that the ground to the lights is bad.

did you look under the hood driver side fire wall

Look in the fuse/relay box under the hood for a fuse labled headlights.

Usually built in to the head light switch or could be located on or under the kick panel by your feet....

go here. we can help you. Also, did you check the headlamp relay in the box under the hood? One relay is in box in front of battery, other is in narrow box along passenger side fender under the hood. swap left & rt headlamp relays to see if it changes.
