Hey guys,
Gotta a problem with my AC. Used to work somewhat well last week. It would be blowing cold air when the the AC is first switched on but stops after a while. After switching it off and then switching it back on, it worked again for a while.

But this week it has stopped blowing cold air altogether. I thought that maybe I ran out of the R134a gas. Before I tried to fill in the refrigant gas, the pressure in the low pressure was already in the high red zone area. It was then I noticed that my compressor is not kicking in even though the AC was switched on. Anyone got any ideas what may happened, from the symptoms described above? Thanks...
