AC Issues
#22
Set to OHMS. Place red lead on one side black lead on other, look at meter; then reverse leads. OL means blocked, any number means continuity (0.00 is a number). Diode is bad if you read continuity in both directions.
Pretty rare the diode is the problem. More likely the engine coolant t-stat is stuck open, if your problem is no AC and digital temp displays ---. Replace it with ACDelco 131-158 ONLY.
