Sound issue when indicating

[Blue]

Hi guys,

I have a weird issue with my 2008 Hoe.

Sometimes, not all the time, when i indicate i will hear a high pitch whistling sound instead of the blinkeng noise it normally makes, for the normal 3/4secs.
It also enforces my engine noise.
It stops like when the normal blinking sound would stop.


And then when it works normally i just hear the normal blinking sound through the speakers when indicating.



It is the same the noise you get when an music amp setup has its signal cable to close to the main batt Cable.
It also then aplifies the engine gas sounds through the amp.



I have a movie of the dash/sound when needed

Ok. Have tried switching the front upper a pillar speakers left/right but it stays.

When it happens, sometimes the turn signal will still sound but it will also sound a amplify the engine sound through it, during the time the speaker is playing the turn signal sound.

When i hit the dash on that specific spot, the extra sound goes away and all works like normal.



But the fact it will play both the turn signal and the engine sound is nit often.

usually when it happens, the speaker will not play the turn signal sound, just an annoying hissing sound / combined with the engine aplification, both through the speakers.
Hitting the dash on that spot, will stop both and revert back to a normal turn signal sound through the a pillar speaker.

anyone any idea’s???
What is below the dash on that spot that might cause this??
And why would it stop and work normal after a bang on the dash?

(The issue returns mind you. Sometimes and hour later, sometimes a few days, sometimes the next time i need to use the turn signal)

so something must be loose somewhere?

Probably loose solder somewhere possibly in the bcm since that is what technically "makes" the sound

do you mean the Body Control Module?

yes that is where the "clicking sound" originates from, try taking off the knee kickpanel under the steering column and smack it directly when the noise happens
