I cannot really say for certain when the problem developed as I cannot recall having to use the high beam or fog lights since purchase.

Coverage and how to read this overview

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.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

My 99/T 996 cab has developed a gremlin. The n/s indicators and repeaters (both front and rear) would not work when the high beam or/and fog lights are switch on. It works perfectly in the day and when only the side light or main beam is used. I cannot really say for certain when the problem developed as I cannot recall having to use the high beam or fog lights since purchase. Any ideas? Bought privately but with a full specialist inspetion that failed to reveal any problems, but that was 10 months ago. Also, how many rear fog lights are meant to lit? I know most jap imports only have one and indeed you only need one (f/s) for MOT. However, only the n/s on mine lights up and its due its MOT next week. I have done all the buld/fuse checks. I have also investigated any short/open circuit in the rear light light cluster Its a LHD. any help would be appreciated

POST 2Original post

Not sure about the electrical gremlins, but I can confirm that there is usually only one rear fog light wired (for the UK market). The odd thing is, there is a housing, complete with bulb, both sides!

POST 3Original post

If your car is lhd that would explain the rear fog light. My near side one is all present but does not light. As for your other gremlins - it sounds to me like an earth problem. When the other lights are off the bulbs may be earthing through the dipped beam circuit. It sound difficult to imagine though. I would also taking a wire to the bulbs for a seperate earth (i.e from the negative side of the battery). Its worth a try.

This is a source reference. Confirm exact model applicability in the original material.
