You have too many problems for it to be one individual thing. It does sound like the signal switch on the column is defective. They are pretty easy to replace. You normally only need to remove some plastic covering and can get to the switch assy which is usually held with two screws which are if I remember correctly torx head screws.

Your symptoms indicate a bad multifunction switch. This switch directly powers all signal lights individually. The brake and hazard light systems also run thru a set of contacts in the switch. Either one or more of the contact bars are worn or dirty and not making a solid connection or the switch housing has separated, resulting in no contact at all. If the turn signal lever feels sloppy thru the detent this may be the case. Replacement requires disassembling the steering column. Airbag removal must be done by qualified person. Proceed with caution. Hope this helps.
