This 03 is not blowing cold anywhere now. I put gauges on it and got 100psi on the high side and 60 then drops to 28psi on the low side the ambient temp is about 84 degrees f. I felt the lines to and from the front expansion valve and neither are cold. In the rear one of the lines are cold but two lines are hot and one is warm. I am thinking that the rear expansion valve isn't working. but I am not sure what the front on is doing. Also I drained all the coolant out prior to changing the rear expansion valve and it is holding -25psi for over 12 hours so I don't think there is a leak. Is there anything that I should be looking at before I pull out the expansion valves and recharge the system?
