A/c Codes 41 & 43?


Recommended Posts


Can anyone tell me what these mean? I have a 95 sc400 w/ 134 system and a replacement compressor about 6 months old. Blows warm (when cold wanted) and cold (when warm wanted) ONLY at idle. Works fine at higher rpm. Does anyone have the proper hi and low pressure ranges for various temps? I believe I'm running above range on the lo pressure side and well below range on the Hi pressure side. The clutch is engaged.
