Hi I have a 99 suburban LT k1500 with rear air/heat. 186xxx miles. I had a belly leak on my compressor so I decided to replace pretty much everything up front. I replaced the compressor, condenser, dryer, orfice tube, evap core and the manifold lines and all parts are acdelco. I flushed the couple of hard lines I didn't replace in the front. I didn't touch the rear at all. I used new pag150 and replaced any o rings that I touched other than the new ones that came on the new parts.
I do body work for a living so I am very familiar with a hvac machine and how to correctly use one. Although I'm no expert on diagnosing ac problems. I ran a vacuum for 1 hr just to be safe. And charged it to 3.8 lbs. All data sheets per gm calls for 4lbs.
My problem is that my air takes forever to actually blow cool air. And when it does its not that cold. It's cool but not down right cold. It gets the job done but i guess i was expecting more since its all new. I have a new recirculation motor i need to install because the door isnt completely closing. Im going to put a temp gauge on the vents to check actual output temp vs ambient temp. So I will report back with that soon.
One thing that has me a little worried is the high and low lines that run to the rear are not at cold or hot as the lines in the bay. The rear lines are just Luke warm at best and barley cool to the touch. Not cold and wet like the front line or the dryer. I don't know if that is a symptom of anything.
I know this is a long post thanks for reading till the end. Any help will be greatly appreciated. Paul
