300 CE AC Problem
We did vacuum the system for about 8 minutes before we charged and yes, we are still using the old R-12 freon. Mark suggested that we convert the system before we attempt any of the new repairs. Do you agree?
Pressure sensors? How would I test to see if they were bad or not? If so, what would they cost to replace and would I replace them before or after the dryer/receiver & the expansion block?
