Hi Matt

There's a "1" displayed with "P-1" blinking lightly behind the "1" that is displayed on the leftside when the CCU is in this mode! Seems a bit unusual. Almost as if it were stuck in 2 different modes simultaneously..

I will follow your advice and attempt to break the rightside "32" value down into binary.

Orogainally, when the "EC" light became locked on, I knew that I must have had a low freon level in the system.....When I put the system into self-diagnostics mode, my #7 was coming in at 7bar, I added what had to be no more than roughly 3 ounces of R134 and it came in between 13-14 bar, though I have seen it dip down as low as 9 bar on hotter days (90 degrees).....I stopped adding refrigerant because I didn't like the minor noises that the compressor was statrting to make......I shut the car off, heard the freon equalize and then restarted the vehicle and turned on the AC.......The compressor was fine, and my left vents got a bit cooler but still no comparison to the right vents cooling capacities......and in no way as cool as they were originally
