LH Headlight Always on!
When my headlights are turned on (low beam) the LH (driver side) high beam turns on, but the RH (passenger side) is working properly. When I flash the high beam switch the LH's high beam remains on, but the turn signal light (orange) illuminates a small amount and the back bumber turn signal also turns on a small amount. It seems as if the low beam wire was cut and connected to the highbeam and now its all the highbeam!
I checked all the fuses in the engine compartment, interior and even check all the wires running from the LH headlight to the fuse box for cracks or tears, but nothing.
Does anyone have any leads or does anything connect to the headlights that may be causing this that I can check? I did have my RH headlight wire harness replace (accident), but the RH works fine! Help......
Does any one know of a Electrician that can help me?

Sounds like an expensive mess that's going to lead to a ticket. I'd pull the high beam fuse and just do without them if I were you until you get this fixed.
The high-beam and low-beam relays are in the "Intelligent Power Distribution Module Engine Room" (I swear that's what Nissan calls it!). The IPDM E/R is behind the battery on the passenger's side - IIRC you have to remove the trim piece around the battery to get to it.
There is but one relay for both of the lights and if that circuity were crossed the voltage would flow down both paths and light up both head lights. That would mean that the left light which is stuck on is wired to another circuit completely!
Fuse #21 is for the left-hand side and #27 is for the right-hand high beams. They're 15A fuses in the IPDM E/R box.
On the left-hand side the high-beams are a red with a black stripe wire, the low-beams are red with a yellow stripe wire.
PS: I'm not a Nissan mechanic but I'm an old USN electrician and live near Riverside.

A ticket indeed...thats why I stop using my Z at night! I would pull the fuse for the left hand high beam, but I failed to mention that my low beam doesnt work. Thats the major problem.. my LH high beam is acting as low and high beam! I cant pull the fuse cause I would be screwed if I need to drive at night.
Thanks for the info......If your willing to take a crack at the problem PM me and we will talk rates....

So do you know which Fuse Numbers are for the low beams?
Thanks for you help.
