there is a flasher under the dash put your 4 ways on and listen for the tick noise find the flasher unit under dash area driver side there is two one for the 4 ways and 1 for turn signals now that you have found them turn on working signal touch the flasher unit you will feel it pulse and hear the noise when you have the one pulseing on working signal this will need replacing can also be in fuse area have a good day
The flasher relay is probably defective. You need to replace the flasher unit. If that doesn't cure it, you have a wiring problem where the relay is getting a constant signal from the turn signal switch. First try to unplug the flasher (it would be under the dash-follow the clicking sound) and plug it back in. If no help, replace the flasher.
There are two seperate flashers, one for the hazards, and one for the turn signals. They are located behind the lower instrument panel below the steering wheel. Turn flasher should be the one on the right. These are also notorious for the front light sockets to corode or burn out. check their condition and be sure to use connector lube when replacing bulbs there.
I'd suggest using the balance and fade controls to cut out each speaker one by one. to possibly determine if you have shorted speaker or speaker wiring. As far as the turn signal clicking noise, the hazard switch is the actual flasher unit for the turn signals, and could be the culprit, but the most likely cause is the turn signal switch itself. It is usually caused by corrosion across the contacts, which can be cleaned out fairly easily, but more typically, the switch is just replaced
Check that the bulbs are lighting and if they don't replace as needed. If they are fine the turn signal flasher is bad. Replace the flasher and the problem is fixed. If you have to replace the flasher the easy way to find it is turn your turn signal on on listen for the clicking . Find the clicking and you found your flasher.
