Refrigerant pressures are relevent to ambient temperature so the higher the outside temp the higher the pressures. Use this as a guide 70 deg.fahrenheight Low side 30-40 lbs. High side 150-200 lbs. at compressor turn off point with cooling fan running. I hope this helps. Take care.

im assuming your talking about the a/c low pressure port? it should be on the receiver/drier(steel can with 2 lines hooked to it) or in the lines connecting to it

I am not sure I thought some of them were on the back of the compressor which makes it hard to see . but one thing for sure follow the low press line towards the evap and you will find it

The ports on my 2005 silverado are on the same line,which is very confusing but, in between the two ports is the metering device (orifice) which changes the high pressure gas into a low pressure gas.The two ports are of a different size,with the low pressure being the smaller of the two. You can put your hand on the line, on each side of the metering device connection and the high side will be hot and the low side will be cold

Its on the Passenger side of the engine bay between the strut tower and the valve cover. It should have a blue cap on it, or maybe a black cap. Follow the ac line coming out of the back of the compressor and youll see it.
