06 Denali AC pressure reading help.

[rigid1]

The compressor cycles off and on. Here are the readings on a 78* degree day.


Compressor engaged low high
23 primarily around 125-130 did get to 225 a couple of times

not engaged engages when it builds to 44 and drops to 23 as it runs. High does the same as above.

Air is warm. Blower control seems to work on all stages. It was replaced last year. Does it look like it is low? Could I have an orifice tube problem?

Thank you

you appear to be low, may want to fill with dye and check for leaks. hope this helps
