On my 72 I had problems with the rear T/S lights (first the left, then both) not blinking. Later the LF light stopped blinking also. I bought a T/S Switch fromMSA & paid around $120 for it. Solved all my problems.

i have a spare (but kinda mushy) t/s switch that works fine. $15 plus shipping... also, check to make sure that all of your connectors are plugged into the right sockets...

I would not give up on your T/S switch so easily (unless you have $$ to burn). They are relatively suimple devices (at least on the 240Z). I you take it apart, you will find out that 99% of the time, it is just corroded contacts inside the switch itself. (You get inside the switch by bending the tabs of the switch out and carefully opening so the springs don't fly out). Clean the contacts with an abrasive (> 500 grit paper will do, anything less will damage contacts) and then the secret is to lubricate the contacts with a conducting type electrical grease to avoid future oxidation. If you still have a problem, ask for the new one for XMAS.

Update:

I cleaned both front signal bulbs and put some dielectric grease on them. Now both flashers work! The T/S switch still doesn't want to stay in the up or right signal position every time but at least I have signals now. Would cleaning the switch help or is it just worn out?

glad to hear you got it fixed!

FYI. VB sells a NOS T/S switch for the '77/'78 280Z for $99.95 plus $16.75 shipping. Mine is getting worse and I understand these will continue to get more scare > more $.

VB T/S switch installed yesterday. Works great. It is not a Nissan part but an aftermarket piece. Swapped out the old capped dash & covered steering wheel at the same time.

i got a 75 280z and the side markers dont blink. just the front and rear. i was told they just turn on and dont blink. thats the way they were made i was told. also my arrows in the dash dont blink when i turn the signals on, but they blink when i have the emergency lights on. i checked the bulbs, and the fuse. any ideas?

side markers don't blink.

do your external lights blink when you turn on the signals?

*EDIT* i read in the other thread that they do, so hmmmm...... maybe a flasher?
