OK here is problem. Nissan headlight switch went bad(the old lose one low beam light). Change out switch and all goes to working. Then go to use turn signal and get just a buzz from the flash unit. Replace flasher. Still buzz and no turn signal. Try new signal unit and still same result. Now I have headlights(high and low), have emergency flasher(work fine) but no turn signal(just buzz when you try them). Have traced wires with factory schematic and can find no problem. Called Nissan dealers(Ha) we never heard of this one, but for $90.00 we will look it over and see if we can find problem. Call asian repair guy, he said I mess things up because I change switch without unhooking battery. Call me shade tree mechnic. Guess what, he wanted $90.00 to fix my problem. Told him thats ok, I will stich arm out window before he gets any money.
The end is has anyone run into this problem and send help. Getting older everyday.
