i know how to read out a relay, i have purchased a mitchell mazda 3 subscription so i will read things out.

i was just asking the best way to diagnose the relay when there is an intermittant on off problem sorry i wasn't that clear.
Expert:  jettadan1 replied 6 years ago.

you could have a low freon issue where the sensor is shutting it down. This could also be a short in the wiring problem. you can do wiggle tests with ac on to check connections. to trouble shoot this condition you have to act like it never works.graphic

 

I am pretty sure its the high pressure switch or connection.
