Front dash control only gives hot air

The rear overhead control works fine with cold air but the front control blows strong warm air only, is there a blend door that could be stuck and where would the location be so not to completely remove whole dash board.

check behind glove compartment there is a 4 or 5 color hoses yellow,red,orange and black in some model there has different color if one of that hoses are unplugged you could found this problem if not tha vacum it's not working good luck

What year and engine and auto or manual controls?

Does the vents switch good?
Got good engine vacuum to controls?
Can you hear or feel blend door switch from hot to cold?
Do you get full heat on cold setting or just warm air?

Also make sure the r-134-a is a full charge.
Low R-134a will rob one end on cooling.
Give us you low and high side readings at idle and at 2K rpm with compressor running.
