I have a passenger side headlight that pops up but will not close.
I removed it today and connected it to the driver's side connection and
it popped up and closed repeatedly.
So I now know that the pop up mechanism works OK.
What else could be the problem? Could it be the headlight switch inside
the car that turns the lights on and makes the headlight pop up or is it
something in the wire that goes from the switch to the headlight pop up
Is there anything other than wire between the switch inside the car and
the pop-up mechanism? Any resistors or something we should look for?
Any ideas as to what might be causing the problem like worn wire
Basic electrical troubleshooting. Start with looking at the voltages in all
of the connector pins. Most likely, you'll find a voltage missing to drop
the light. If so, you start backtracking to look for broken wires. Not
likely it's a resistor problem - there probably are no components in that
circuit that you would need to worry about failing. More likely just a
broken wire. As in any automotive wiring problem - always start by making
absolutely sure that you have good grounds.
Had a friend's daughter's boyfriend look at it and he checked the
voltagae and said it wasn't the wires. He thought there must be a
control module or something.
I think there is something behind the passenger side kick panel.
Any other ideas?
What do you mean he checked the voltage and said it was not the wires? Was
there voltage present as it should be? That would point to a faulty light,
but you already proved it worked on the other side. Was there no voltage
present? How did he then determine that it was not the wires? I'm guessing
he did more tests, but your comment does not indicate so, and your comment
causes some apparent contradictions. It would be helpful to know exactly
what he did.
If the voltages appear the same on both sides, I would be more suspicious of
a bad ground on the failing side. I am reading into his statement a bit,
but if he's seeing the same voltages, then it almost has to be a bad ground.
Bad grounds are the number one electrical problem in cars, and cause the
most unexplainable symptoms. Circuits will feedback through other areas,
and present confusing symptoms. Like you - I'm trying to think this through
without the fullness of understanding what he did and what he really saw.
