No turn signals
 

My main issue is that I have no turn signals the cpu clicks but no lights in the cluster or at the bulbs. Lights work brakes work I have no idea now. I have exhausted all my possibilities trying to track down this problem thus far I have, replaced cpu as well as harness, replaced switch both wiper and turn signal, checked fuses both turn and hazard, unplugged all turn lights. Any suggestions would be awesome thanks in advance.

the fc's are known for the tss going bad. id suggest getting a schematic and a friend with a fluke meter help you diagnose it.

Ya i have a fluke just not with me right now what is the TSS i have never heard of it before. Thanks

TSS=turn signal switch

Signal switch is good tested it on another car of mine same with cpu

well go get your fluke meter and a wiring diagram.

Im gonna bump this thread up because Im having the same exact problem.....

I hit me left turn signal, It clicks on and off like they are working but nothing at the exterior lights or the 2 arrows in the cluster. Same thing with the right. What is the deal with this?

Ive been searching and the CPU seems to be the problem most of the time. The OP stated that he swapped his CPU for a known working unit and its still doing the same thing.

My car does the EXACT same thing the OP's does.

To test the CPU circuit board you'll need to verify voltage at the Black/Blue wire although from reading your post you likely have it but measure it anyway. After you find that you have battery voltage on this wire then use a jumper wire to connect the B/L wire with the Green/Red wire and the left turn signal should flash as you should get a pulsing voltage on the Green/Black wire. If this does not occur then the circuit board is the problem. You could also jumper the B/L voltage wire to the Green/Yellow wire and the same thing should happen with the right turn signal and respective Green/White wire.

This needs to be done with the plug connected of course and you might want to unbolt the CPU at the top to help create more room to work with cause the room is a tight fit
