Basically the title.

A/C was converted to R-134 back in 2011 (P/O). Worked well for a couple of years, until last summer, whereby I imagine it sprung a leak. It no longer blows cold/cool/tepid...

I don’t have the tools or equipment to refurbish it all myself. I was however hoping there were a few things I could do to either save on labor hours, or at the very least isolate the issue to save on exploratory with my indie.

To be honest though, i find it all a little overwhelming and am not sure where to start. Vent system? Change expansion valve orings? Drier? Take it to a shop and ask them to pump it with dye? No idea where to start...
