My 05 tj unlimited a/c is blowing, but not cold. Fuse & relay are good. What should I check next? I noticed the radiator hose on top is VERY firm, would stuck thermostat cause it not to cool?

Is the compressor clutch engaging for a few seconds and cycling on and off.

First off… Is your a/c compressor kicking on…?
 
AC systems or some thing that you can DIY but you have to have the right equipment… My recommendation is but somebody who has the equipment and knows what to do… There are plenty of good YouTube videos showing you how to check it but if there’s no Freon in the system that means there’s a leak and parts will have to be replaced before I could be recharged…
 
Radiator hose shouldn’t have any bearing on AC not blowing cold… If the clutch on the front of the AC compressor is not coming on, then that’s why it’s not blowing cold air…

But if the thermostat isn’t opening & letting the coolant cycle wouldn’t that heat things up?
 
No… The radiator hose will have pressure because there is pressure in the system but if you got the proper radiator cap on the radiator, it shouldn’t be more than 18 psi… 210 is about right
 
It doesn’t seem to be gauge was below 210… but engine bay was pretty hot when I popped it open

Hise was firm, bay was hot, let it cool, hose still firm, opened cap, pressure on hose relieved…

Ok. Thanks. So the a/c compressor is bad?
