Hi everyone! First time posting here on this forum, so please be gentle

I have a 02 Suburban 1500 LT which has started having a few electrical issues. First off, the turn signals does not work (no flash on dashboard, no flash on lamps) UNLESS the hazard signal-button is pressed. At that time, the right side turn signals all work as expected (flash on dashboard, flash on lamps), whilst the left side turn signals indicate that they are working, but there is no lamps are not flashing (flash on dashboard, no flash on lamps). For easier understaning:

* Hazard-button OFF + Left/Right turn signal ON = No signal on dashboard nor lamps
* Hazard-button ON + Left/Right turn signal OFF = No signal on dashboard nor lamps
* Hazard-button ON + Left turn signal ON = Signal on dashboard and lamps
* Hazard-button ON + Right turn signal ON = Signal on dashboard, but not on lamps

There is no fast/rapid flashing on dashboard, just regular-speed flashing. What might be the issue with my turn signals? Both the front and back turn signal bulbs on the right side are replaced.

replace all signal flasher units. they are fried and using the hazard flasher as a circuit....Should just be two. Make sure you have no exposed grounds from bad wiring and trailer hitch plugs.
