Customer Question

2004 surburban 1500 A/C compressor runs clicks on and off, accumulator gets very cold yet
warmer air is blown into truck. Can this be a problem with a switch of some kind? Had A/C
operating fine last week.

Hello and thank you for your question,

Are you able to install a set of AC gauges and read the pressure on the low and high sides?

Customer: replied 1 year ago.
no, held accumulator line as it began to get colder.

I'm just a guy who paid to have his driver side actuator changed to keep the driver side cold when the A/C comes on.Itarts frequently starts putting out hot air instead

The compressor cycling off and on is usually related to a pressure concern, is there any way you can get the pressure tested and get me the reading?

It not very likely that both blend door actuators have failed again and I suspect you are low on Freon but I can not be sure with out knowing the pressure readings.
