1. when i get in my car i notice my security light is flashing on my dash. when i put the key in the car it starts as normal with no issues and the light goes off. Any Ideas ?

2. no Door chime when door is opened (Factory radio)

3. Turn signals don't blink just Illuminate (swaped hazard switch no change all lights come on)

Any advice?

Update #2. Door chime fixed itself.

Update for #3. Hazard lights started working but they are blinking like crazy if I switch to the old switch they manage to blink even faster it's almost like a bulb is out on both sides but all bulbs function

Weird suggestion, but are all grounds and battery leads tight? I've still have yet to experience the persistent security light issues some have on these cars, but the few times I had a sporadic light it was due to the battery being loose.

I will definitely double check that, it only seems to blink if I have the door open before I start the car not before or after.
