when you hold the accelerator does the vehicle stay running? if so the problem is in ithe IAC idle air control motor, take a small screw driver and using the handle tap the iac motor and usualy the motor will kick in and the vehicle will run fine then if the problem is rectified replace the IAC

The flasher is the round most likely yellow but could be silver mounted in fuse panel. The hazard flasher is located on back side of fuse panel directly behind it.You can remove it and insert it in place of the turn signal flasher to see if it is bad.

Sounds like the multifunction switch. Try working the hazard switch up and down a few times to see if you get some lights to work. If so then replace the switch.

Had a similar problem. Solved it two ways first place key in the 3 position move gear to N then start and it will shift easily. Second solution check brake light fuse, it is probably blown replace it and gears will shift OK.
