A/C was working then parked for the day following night A/C would not come on. hooked gauge set up and static pressures were 77-79 PSI at just over 70 ambient air temperature. applied external power and low side was 44 PSI and high side was 172 PSI. replaced the low pressure switch and the high pressure transducer and the A/C worked again that day. that night not working again. checked pressures again still the same. when its on its cold air front and rear and even evacuated the system and it holds a vacuum for 2 hours at -30 PSI.
when you turn the A/C control inside on the light illuminates nothing happens. add power directly to compressor and it works changed the relay and checked all fuses to make sure.
seems like it works when its hot out but under 75 degrees outside noting. there is no ambient air temperature sensor i can find behind the bumper like in the diagram but i also don't have the outside temperature display.
i'm lost on this one in can go home today and it will probably fire up but around 6:00 pm when the air drops outside it then wont work.
any help would be great.
