Default Help with Headlight woh's

I installed a set of 9005's and 9006's HID's from VLED's and now my headlights will not open on there own. If I click the steering wheel stick to lights on they do not open and do not turn on...but if i pull the stick back the lights go up and both high and low beams are on. Anyone know why this would happen? I cant use the car at night becasue my lights will not work correctly. I need to hold the stick back as if I were flashing my high beams at someone just for my lights to work!! HELP

Did you add a resistor when you installed them? Did they come with a relay harness that runs from the battery to the lights or do they wire in at the lights?

They came with relay harness but dont run to the battery they worked perfectly for like 1 hour. I was ****ing around up and down and up and down with the headlights to make sure everything worked good. I think It might have nothing to do with the HID's what so ever I think its a headlight relay or weird thing like that...

In theory nothing happens when I put the low beams on the steering colum...but if I were to hold it back to flash the high beams the headlights motors come up and both low and high beam are active.

Is the battery weak from all the time you spent working on them and trying them out? Also check for a blown fuse.

Update: Night time came and I tryed it again the low beams dont come on at all when I flick the switch to turn lows on the motors also dont raise the headlights....But if I were to pull toward me the switch to flash the high beams they come up then if I let it go they go down....basically when I turn on my lights dont come on or raise up.

Is there a fuse for low beam/on? I can flick the switch to parking lights and they work, flicking it to headlights doesnt bring up the motors or the head lights. While in that state I can push it foward for highbeams, nothing happens. If I pull it back to flash to pass the motors go up & high beams go on but no low beams then if I let go the motors go down.

I've known that fuse to be the problem in the past. I cant see why just putting LED bulbs should have caused issues so I'd be looking at the motor side or the switch. Hers the troubleshooting guide. Run through it and see how you go. Its read as a 4 column table (Step, action, yes, no) so its a tad confusing in text format

Not that I'm aware of on the stock system. The relays are upstream. I have but I have high voltage T85s (Euros)

You can see from the wiring diagram, the switch directly controls the headlight modules

You can discount a lot of the checks in the troubleshooting guide as you know some parts of the system are working.

You know the headlight motors are good as they work on flash to pass. You also know the high beam circuit is good.

Fuses 8 & 10 underhood are the low beam fuses.

If they are good its pointing at the switch. They are well known for failing. As a start try some electronics cleaner squirted into the switch. If its a dirty contact that may help. It could be with all the recycling you damaged a contact.

If the switch has failed on the "switch on" circuit what you're seeing is logical.

This is where you went wrong. Did you switch out back to your halogen bulbs to rule out the HID kit?

I'm going to do that tomorrow. Is there something I can bridge to have my low beams come on to test and see if they are working?
