Leading evidence: 'light switch as well' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'light switch as well' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Check blinker fluid' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

01 996, both will fail to ignite. If you then push the high beams lever, they ignite and rotate up as they should along with the high beams. Could it be a faulty light dash switch or anything else/
Had the same issue on my 01 X5. Had to replace the bulbs. Lights flickering is usually HID bulbs as well. Go for original Philips as troubleshooting HID issues is "nightmarish". Also do both fail to ignite the same time or will one turn on, while other won't? Does turning the switch back off to on help?
Same here, if both do it, much more likely it is the headlight switch than bulbs or ballasts. Had to replace mine with only 39k miles on it. Not expensive and easy to do. Got mine from Sunset for about $70 IIRC.
Same issue with my car but sometimes just turning them on and off would gett them to ignite. Sometimes a high beam flash would do it. In the end (about 4 months of this trial and error) they failed to ignite almost all the time. The solution was the light switch. Has been almost a year now and never fails to light.

I also had the same problem a couple of months ago. It turned out to be the light switch as well. I would advice you yo start with that. Change the switch is an easy DIY.

As far as a DIY, check over on Renntech. It's very easy.
*Remove Headlight switch
*Remove A/C vent
*Remove Headlight Switch Assembly from A/C vent
*Remove Headlight switch assembly from wiring harness.

Hi, I am having same problem with Litronics on my 2004 986 Boxzter S. Bulbs flickering, replaced them and new bulbs did the same until now the main beam does not work at all.
So I am assuming the headlight switch will fix this based on all of the earlier posts. I checked the p/n and that fits a 986 also.
Where I am stumped is for DIY, where is the headlight switch located and how do I get to it to replace it.... Any links or suggestions anyone?
