Where is the turn signal flasher located?

I first replaced my turn signal switch arm because my right turn signal stopped working. However, my hazard lights were still flashing together with a faint clicking sound. I later realized that the switch was not the problem. So, I did some more research and guesstimated that it was my turn signal flasher gone bad. So, I purchased a new flasher for about $62.00 and thought I would save money by replacing it myself. When I dropped the bottom panel on the driver's side, I found a Bosch relay connected to my APS 514N car alarm, which also stopped chirping along with my car's program chimes and right turn signal. I cannot find the flasher's location. I started thinking that maybe it was changed to the Bosch relay during the custom installation of my alarm.

Hi,

This vehicle doesn't have a traditional flasher unit for the signals. Instead, the body control module (BCM) controls the vehicle turn signals based on inputs from the turn signal/multifunction switch. With the turn signal/multifunction switch in either the left or right turn position, a ground is applied through the turn signal switch signal circuit to the BCM indicating a turn signal request. When the specific request is seen, the BCM then applies a pulsating voltage through the front and rear turn signal supply voltage circuits illuminating the turn signal lamps.

Have you checked fuses? Each side has a separate fuse for the signals. Fuses 7 and 11 in the vehicle fuse box (below radio) need to be checked if you haven't. (See pic 1 below) In addition to checking the fuses, confirm there is power to and from them. The ignition key will need to be on when checking for power.

Start there and let me know what you find.

Take care,

See pics below. Pic 2 shows the fuse locations.
