Well, There was (2) issues I think I was having. (1) the short cycling I was having when I came to a stop or slowed down was the fact that I had too much pressure or Freon in the system. What was happening when I put a gauge on it was the pressure would spike and go back down and it would keep repeating this as long as I had the A/C on. Come to find out, I put too much coolant into the system (Didn't pay attention to the gauge the first time). (2) I did have a leak. Fortunately for me it wasn't a big one and was remedied by a can of coolant/sealant... I was able to let some of the pressure out, and my truck now has the proper amount of coolant/pressure (Using a gauge this time
with a vent temp of around 55 to 60 degrees.
But, at the same time it's only the Driver's side that is truly Cold. The passenger side is cool, but not cold. Which does lead me to believe that it may be the blend door. Hopefully I can find some time to get in there and replace it in the near future and follow up with everyone on how it works out.
So for now, I have a properly working A/C system again going into another TX summer... Which is a huge relief...
