70PSI, is bad news. go ahead and turn the blower down to low and put it in recirc/max mode and see if you can get the low side any lower. it would be much easier to offer advise if you can tell us what the high side/discharge pressure is. i would bet you high side is low too. the only thing you can do if it is, is to maybe inspect the orifice tube but more than likely the compressor is weak.
low side normals are usually between 25-35PSI.
high side normals are usually between 150-300PSI.
these pressures will vary depending on ambient temp, blower speed and which a/c selection you are using.
what happened to mine is the line with the disharge fitting on it that goes by the intercooler tube it rubbed threw on it. so had to replace it and recharge the system, and that is on the high side mine sits at, 30 and 200.
It is very cold and nice, Im not sure how much it was i would have to find my recite im trying to but i seem to have misplaced it. but i just bought the line and installed it myself and charged it myself.
Hey guys well i got the truck back from the dealer and they told me that a valve on the lower side was leaking so they repaired it and recharged it. now it blows super cold cost me $172.00 with tax no warranty anymore.
