Question
I cannot seem to clear the f12 code (lowside). installed new compressor,orfice,accumultor and flushed system. What is the location of the ac temp sensor lowside)it is talking about, changed the system to 134a. how much pag150 and 134a should the system hold.
You CANNOT replace the R-12 freon to R-134a freon because the 2 types of freon are not compatable with each other and operate at different pressures when in the A/C system.
The only way to CLEAR the F12 is to install the original R-12 freon and then the code will clear when you use the climate control panel to clear the F12 code.
