Another A/C Problem

I have a 99' Expedetion XLT, I have the rotary button A/C system that went out on me. I thought it could be a leak but after adding a can of R134a it blows hotter than before what gives? The rear has no cold air coming out at blows hot. Did a search and didn't come up with much on adding R134a and and blowing hotter air, can someone help?

*WARNING* R134a will KILL you, I had a car with a slight leak and kept topping it off, cheaper then fixing it? Not-It caused me cardiac arithmia, almost died from it.

I agree with puppypower. You might have a blend door problem. If the doors don't direct the air towards the evaporator then you will get hot air. Hopefully you checked the pressures for the A/C before adding extra R-134a to the system.
