A/C issue too much pressure
Hello hopefully you guys can help.
07 GL450.
AC stopped cooling. Hooked up 134A charger. compressor is a cycling on and off every two seconds.
Compressor kicks in at 50PSI and shuts down at approx. 90PSI.
blockage maybe?
Attached link of video that shows issue.

Your low side pressure is too high so your a.c. system will not work. Get rid of some.of the low side pressure until you see the pressure return to normal. The low pressure will start to feel cold when em you get the pressure correct. I believe this is a symptom of your compressor going bad.

Out Of Control!!
I think some meat head over filled the system with the handy dandy hand held BS spray!----Now it's off to where someone should have gone in the first place----a good shop that knows what they are doing!
