When first turning on ac temps at vents around 55 degrees as time goes on temp slowly rises whit higher temps being in the left vents. Why would the temps go up and why would there be a difference in the temps in the vents?

Could be freon level, mode door positions, mode door motors or air leaks inside the vents.

There is no way to check refrigerant level short of removing it all, evacuating and recharging with the correct weight.
