I woild be checking the vent controls as if the ac is working and the core was blocked then the air would be cool when the heat was selected but not changing Fixing the heater has resulted in a /c not being good enough to cool the air if the vent is not properly selecting. The point is that if the vent selection is not working properly (vacuum hoses) then the 2 faults will be related.
Usually a sign of a stuck blend door under the dash. Could be a faulty blend door actuator, or the main controller. You may need a shop manual to make the repairs since this is generally beyond the abilities of a DIY repair book.
Probably, to be sure make sure the compressor is coming on. With the engine running turn on the ac and watch the rpms, they should drop for a second if the compressor is coming on.

The kit will come with detailed instructions and is a pretty easy job.

I have a 2002 Jeep Liberty and after driving for about 30 minutes the air conditioner would start to blow hot air. The air conditioner clutch was sticking. I could hit the clutch and it would kick in and start to work. I went to Advance Auto and purchased a big spray can of electric motor cleaner and a big spray can of WD-40. I soaked the clutch with the electric motor cleaner, used the whole can, then soaked it with half a can of WD-40. The clutch has worked perfecty ever since.
