No Power to A/C Compressor
#4
I'm not sure if 0.fl means open circuit to ground or closed circuit to ground.
Look in that fuse box for an identical relay for something like the rear window defroster or power window. Swap the relays. See if the a/c work and the other component stops working.

Olf meaning out of limits I presume I have already performed a relay swap replaced the relay the pressure switch(was showing 0 data and still is) and I have replaced the compressor witch was bench testing bad I can jump power at the relay and get the new compressor to kick on I have tested resistance to ground on the compressor the pressure switch and I even went as far as testing the ambient temp sensor with a heat gun and a cup of ice water futhinging normal on the resistance scale heat low resistance and cold high but I can not read any data on the temp or the pressure sensor when actuated from the pcm everything shows on (compressor and ac button internal to the vehicle)

I moved your posts to a new thread to make the original less confusing with two potentially different problems. Put your car info in here (year, trim, ex, lx, etc, transmission) and we can start troubleshooting.

That works. In the common diy thread on top of the gen tech help forum, there is a link to checking hvac codes for your generation accord. Give that a shot and see if you have any hvac codes that can give you some direction.

Lets take a step back. You can leave the relay plugged in and unplug the connector to the a/c compressor. Using a test light, you can verify if you have enough power to light up your test light with the engine running and turning on the a/c.
Alternatively, if you unplug the relay, you should have 2 pins that are larger and possibly better metal, like copper. One should have 12V and the other should have some resistance to ground through the a/c compressor coil. What happens if you use a piece of wire to jump those two pins on the relay box? You are essentially using the wire to act like the relay.
