AC compressor Clutch would not engage. Found TIPM input to Compressor with zero current.
Usually a comp/clutch failure causes high current draw from TIPM and hence NO power output at C9-3 DB/YL wire when there is triggering grounding signal at C2-10 LB/OR wire.
And this is a common AC issue with the TIPM.
Its rare that the ECM fails to send the triggering signal.
