Wiring issues, turn signal bose

[JTown77]

So there are a few issues that I have found on our spare allroad as I am prepping it for sale.

The turn signal will come on but not flash. I replaced the stalk about two years ago. Is there a relay somewhere that controls the flashing?

The bose speakers were toast so I purchased a set of components and installed them. The front left sounds normal while the front right sounds like it is flat with no bass at all. I have installed plenty of component sets in every car i have owned in the last 20 years. I swapped the woofers and the passive crossovers with no luck. Somehow it seems as though the signal is getting degraded somewhere, I am not sure where to look. Are there connectors between the HU and the Bose amp other than at the amp and HU? Is there a connector some where between the amp and the door card plug?

One of the door latches was doing the Audi "I dont want to do my job" dance, so I replaced it and now the remote lock/unlock no longer works. Is there something I need to program through VCDS to address this?

And last of all the damn air bag light is on in this car as well as my other two, all three read intermittent grounds i believe as well as limits being exceeded. If I recall correctly all three cars it reads as the right side air bag. Isnt there a plug in the center console that is to blame for this or is something else going on? Module?

The turn signal not flashing is because of the hazard switch in the center of the console. That switch is a relay and engages the turn signals and hazards. When the switch started to fail on me, sometime the blinkers would work, other times i would have to fiddle with it just to get them on. so i changed the switch (around 40-50 bucks) and all is well.

The speakers, well i didnt touch them for this very reason.

The airbag, probably an airbag connection under the seat. They commonly get messed up and require cutting connection off, putting i think 3 separate female connectors on, one for each wire, and then plug into the seat. Just make sure each wire is plugged correctly and not crossed. Airbag could explode. Disconnect battery before you do anything haha.

And for the door latch, think you need to vagcom it. Not sure though

The Bose system if I recall correctly requires 2ohm speakers not 4ohm. So if you installed regular 4ohm components then now you are trying to draw to many ohms which is why I believe one side is working and not the other. The flashers have been cover already. The other stuff I don't know

The error with the speaker was that I had used the tweeter wires rather than the woofer wires as supplies. Once that was remedied, no more speaker issues.

I'll look into the hazard switch as mentioned.

Thanks for the suggestions so far.
