Ac unit not blowing cool air on passenger side
Here is the solution to your ac problem with the passenger side not working. The AC unit has a default switch when the Freon level is low. This default switch will provide cool air to the drivers side and push hot air to the passenger side. This way when the Freon is low the driver will not be hit with hot air blowing in their face which will cause them to pass out.
I added Freon and everything works great now. Please ensure you use the lower connection which is also identified as the fatter line when inputting the Freon. Hope this helps.
