My A/C was blowing cold and hard like it always has. While driving down the road it starts blowing hot air.

I have pressure in the lines but the compressor is not coming on.
Can it be the Clutch and not the compressor?

 

Yes, it can be all the above. You didn't mention how much pressure you have in the lines. It is possible too that you don't have enough, a fuse blew, or the AC button was not pushed (yep, I had a buddy who swore his AC was broken only to find out his bride had turned it off the night before!)

 

I will have to check the pressure again to get the exact number. We did rule out the fuse and the AC button being pushed lol I turned it off and on several times just to make sure.

I took it to a shop today and was told that it was the compressor. My father is a mechanic and he is more convinced that it is the clutch.
