I have 1999 Toyota Camry. The tun signals and hazzard flasher do not operate. The bulbs and fuses are good. The front lights light up but, do not flash, the back lights do not light up. The under dash flasher clicks when the turn signal lever is activated.

Indeed, there are quite a few wires with different colors.

Perhaps, if it is too hard to do with a test light (self powered or not self powered) the safest thing to do is to take the vehicle to an 'auto electric' shop that specializes in this field.

They may be able to diagnose the problem within an hour or so.

If you want to do it yourself, you can try, but sometimes it can be frustrating because of the number of wires that you have to sift through to get to a solution.

And, there's always the risk of shorting something out that you don't want to.

Part of working on auto electric problems is getting to the right wire without damaging other systems of the vehicle.

So, that's why I would recommend an 'auto electric' shop for this problem, since fixing this type of problem is more advanced.

If it were just a flasher, I would say that you could change that yourself. Indeed, there are quite a few wires with different colors.

I'll make a mental note of this solution.



Sometimes the flasher contacts are bad even though you hear it click, it doesn't make full contact.



Thanks for getting back to me on this.
