Warm air is blowing out of vents, A/C compressor is not operating (unless the A/C relay connector terminal C and D are shorted (step #9), but still doesn't blow cold air), inspected Low pressure refrigerant (good), indicator light is on, the refrigerant pressure switch terminal C and A has voltage (but when A and C are shorted there is no cool air is blowing out), and changed A/C Relay switch with known working fuse of horn with no change in magnetic clutch (also, terminal A and D has voltage).
Not sure about:
Step 3 - High pressure test (I don't have cables to test)
Step 8 - DTC codes - just replaced an oxygen sensor and waiting for all codes to clear
Step 19 - Wasn't sure where "Test voltage at PCM connector terminal 69 (iG1 signal)" was.
Step 22 - Wasn't sure what it was talking about.
So, it looks like I stopped at step 27 - Magnetic Clutch connector terminal A is not receiving voltage (unless I test it as the when I have shorted the A/C relay connector C and D). It says to replace wiring harness between A/C relay and magnetic clutch. To me it seems like it is getting power when shorted so confused about this. Also, is/could the problem with the Magnetic clutch since it doesn't blow cold air even when it is shorted and runs. Just want to know what should be replaced, I hate to spend extra money on things that don't need replaced and to find it's still not working after they are replaced.
