I'm trying to get some colder air out of the old truck and working through the steps. I put a thermometer into the vent to the right of the climate controls and read 70 cruising around at 45mph or less and ~60 at 55mph - outside it's 99. Now I am wondering if the Dieselsite shutoff for the A/C is going to do the same thing as this and if I'd be wasting money or if it might help-
I'm going to hook up a manifold tester to check my pressures if I can find some time of day when it's not over 90. I've found no leaks in the system and when I hook up my cheap-o gauge to the low side I get a reading of 55psi on a 95deg day sitting at idle in the drive way. This seems high from what I've read.
I'm really at a loss and don't want to throw money at something that's not broken and the shops around here want to just re-charge the system and I don't think it needs charging due to the pressures I've seen so far and really don't want to replace everything in the system.
