So I had the dreaded clicking on close of headlight from the left assembly. They went up and down but the gear just spun on the left side when closing, so I got a replacement headlight (because I haven't found the gears available recently) and went to replace it.

Switched headlights on, both headlights came up just fine. Removed and reinstalled left headlight.

However... I forgot to plug it in.

Turned ignition switch back on, turn headlights off, only right one goes down. Crap, go back up, plug the left one in, but it won't go down. Try to turn them back on, right side won't go up. So I'm stuck with one headlight up (left) and one headlight down (right). The lights will light up, but no headlight movement.

How to get them back working again? Thanks!

 

I would try to manually turn down the one that is up, then pull the fuses to #3 and #4. Wait 30 seconds and reinstall the fuses, then turn the headlights on. Hopefully they have reset back to normal...

Fuses are for each headlight door motor which is controlled by the headlamp door control module.

Good luck

 

Thanks, I appreciate it. Need to figure out how to crank it down, haven't done that before. The dial on the back of the motor that is stuck in the up position won't move easily.

It acts like it sensed the motor was not attached and said "nope, you can't have headlights" and faulted the controller. This is a project C5 and it has a ton of problems. ABS light on, service traction control light on, DIC scrolls through the faults but none of the other buttons that control it work, can't get the mileage, nothing.

Bought it as a salvage car to give to my dad after fixing (light hit with telephone pole dead center front bumper almost fixed with body work) and whoever had it neglected it badly. Had to replace the radio because the on/off button didn't work, sent the AC head unit in for LED repair - controls worked but it was dark, lots of broken interior panels. Just years of neglect of small stuff that broke until it was a LOT of small stuff.

Hoping it's not the BCM that went bad with all those faults.

One thing at a time.

 

Well that didn't work.

I checked and reset the fuses for the headlights, didn't do the trick. More importantly, I ran both headlights up manually while the switch was on, disconnected both lights, pulled both fuses, disconnected the battery, and ran some errands. Came back and put everything back together, no lights. Turned the switch on the stalk off... both headlights dropped. Will not come back up.

(bangs head on wall).

Looked closer and NONE of my running lights will come on. Not in the running lamp position nor the headlights on position. Pulling lights into bright will make headlights flash, but no lights come on at all.

I have the 3rd brake light when I push the brake pedal, but no brake lights.

I have turn signals in the back, but not the front.

What the HECK is going on with this thing??? Ideas?

 

Per the manual, If the headlights do not come on the doors will not open. So your headlights and running lights are not coming on, check the relay, fuses, grounding points, or multi function switch... see attached wiring diagram...

 

Thanks, I think I saw you post that in another thread on here. I'm going to go out today and check the fuse and grounding points (car is up at a local shop for the oil pressure sensor because I'm just not in the mood to do it).

The car took a front end hit and just left the shop where they had to cut out the front center frame support, straighten the frame a 1/2cm, then welded another frame support on so it's possible the ground got crimped or otherwise damaged or disconnected up there.

 

Alright, went out to the car today. I have turn signals front and rear and emergency flashers rear.

I do not have main brake lamps when I push the brake pedal in (although I have the hatch red light so it's not the pedal switch).

I checked all fuses, none of them appear to be bad. I can get headlights when I pull the stalk/lever back but they don't come up, they just turn on in their bay until I let go of the stalk, so there's power to the lights.

There's just a control module for both the running lamps and the headlights that isn't functioning. The odds it spontaneously died swapping a headlight seem to be pretty low but, maybe.

By that diagram it can be one of only two things, the headlamp relay in the fuse block right passenger kick panel or the Headlamp Door Control Module in the right front wheel well.

The fact that the running lamps aren't coming on directs me away from the door control and to whatever controls the running lamps which I don't see in that circuit.

Any idea where that control module is located? For the running lamps?

 

Typical when I pull back the multifunction stalk switch (Hi beam flash) when the headlight doors are closed, they remain closed and fog lights will come on.

I would use a meter and check voltage at the headlight fuses. Also check continuity of each headlight circuit to ground.

Here’s wiring diagram for a 1998... it shows the Daytime running light module.

 

So I didn't have time to work on it much today, maybe this weekend, but I did go pick it up from the shop where they were replacing the oil pressure sensor because honestly I'm just too busy to drag the intake off and such.

They tell me that as soon as they pulled it in the bay, the sensor realized it was dark... and turned the headlights on.

What... the heck. (bangsheadonwall)

That sensor is part of the DIC that isn't working on my car, so obviously it's plugged in enough to trip the headlights. Just no control of headlights or running lamps with the stalk switch spontaneously out of nowhere.

So, to recap:

Headlights will work if they sense darkness but otherwise do not, so enough of the system works to engage the lights through that circuit. Covering it with my hand is not enough to trigger it oddly enough.

When I unlock the doors the reverse lights, brake lights, running lamps, and fog lamps will flash, so they're getting power.

No running lamps or headlight control through stalk.

Possibly the headlight relay? It looks like that grey line C1 / 103 coming up from the DRL controller goes to a different part of the relay and activates the headlight system.

Otherwise by the diagram, if I get running lights and headlights from the DRL control module, then it may just be the stalk went out on me simultaneously with me messing with it?

 

It was the stalk / switch. Got a used turn signal / switch off eBay, plugged it in before taking the column covers off and sure enough, headlights popped right up, although the right one is slower to come up than the left and the right one also slams down fast and hard compared to the normal function of the left. Not sure what that's about yet.

Headlight switch installed and all is well except I still don't have brake lights. Hazards work, 5th brake light works, turn signals work, just no brake lights. I suspect the Hazard switch, ordered one of those today too.

One thing at a time. Got the blower fan replaced today as well as a new cluster ordered for my DIC buttons that don't work. All in all only half the items inside the car is working properly. Whoever owned this prior to me really didn't take care of her. We'll get it all sorted shortly.

 

Got the cluster in, DIC buttons all work now. Still no HUD. Mirror doesn't work, ordered a replacement HUD.

Got the Hazard switch in, $25 bucks off Amazon, here the next day. Brake lights work. Sweet!

Just need to get the front turn signals and such working again and I'll be done with all lighting issues, then just inside stuff and ready to rock!

Thanks to all for the help!

 

Well, that was short-lived. Back to the right headlight coming up and the left one not. Fuses are fine. Guess I'll try the relay next. SMH

 

Oh and I have intermittent blinkers too. awesome.
