Have you tried replacing the high beam bulbs yet or at least checked to see if power is getting to the headlight or not?
No power to high bulbs but they work. I put them in my friends Escape.Have you tried replacing the high beam bulbs yet or at least checked to see if power is getting to the headlight or not?
Thank you. I was thinking it was the switch and I had tried a similar switch (I have the manual switch but all I could get my hands on was the switch with Auto dimming and fog lamp controls as well) It did not work but I assumed it was due to the wrong signal from the switch. I also did not get any codes when I checked them so I assume the BCM and HCM were talking and not dead as that should throw a code from what I have been told. I have not checked the BMS sensor/pigtail. Not sure where it is but I will take a peek. I was just trying to pin this down before I purchased the switch as they are around $150 and not able to return them if it is not the bad part. They got you coming and going.There's no HCM in this year.
Your possibilities are:
1) Bad headlamp switch
2) Check the BMS sensor and/or pigtail. The headlamp function is logic driven via the BCM and if the LIN bus isn't working right all kinds of strange things happen.
Thank you. I will check it todayThe BMS sensor is part of the negative battery cable, it's located on the post side.
Thanks Yes I have tried that. They used to work correctly but something happened in the system that caused the high beams to not turn on at all and the low beams to act like DRL. I have been told that it is a missed signal to the BCM that causes that behaviour.Have you tried turning on the switch to see if the high beams work? I know that is a silly question, but my '13 has the low voltage, low beam DLR's. Meaning that my headlights come on when I start my Escape. The high beams only work after I physically turn on the switch. Same goes for the tail lights.
I had the same concerns about the headlights when I bought the vehicle, but was informed certain fleet vehicles and rental companies ordered them with this function turned on. And they are controlled by the BCM.
Why do I have DRL's?
