Hey BB!
Ok, I finally was able to replace the evaporator and refilled (for the 7th time) with 134a. Compressor came up and cold air was flowing again. Not the greatest but at least when it down into the 80's down here is works pretty good.
It has now been almost a month since the change and it is still holding. I think I am going to buy a set of Red Tek and wait till spring to install. If the system holds the 134 through the winter I will be more comfortable it will hold the Red Tek for some time.
Keep you updated but even a little cool is good
