In order to check the basic system functions a jumper cable is placed in between the two terminals the go to the relay contacts. In this instance they are the two larger terminals that operation parallel come each various other at one finish of the relay. Caution: Jumping the not correct terminals can permanently damages the engine computer. With the engine running the a/c compressor must be on and the a/c light should not be flashing. This would indicate that one of two people the relay or the regulate wire circuit indigenous the computer system to the relay is in ~ fault. In this situation the light to be flashing when the relay to be bypassed. The a/c compressor to be on, the pressures were normal and the vent temperature to be cold. Caution: do not leaving the jumper wire in place for much longer than a couple of minutes even if the previous problems are met. Also less time if those previous problems were no met. Operation the compressor in this path is for test purposes only. Compressor damages will take place if this cable is left in place. The flashing a/c light under this test problem can indicate that there is a problem with the compressor speed sensor.
I had a analysis of 99.2 ohms. I could not find the specifications because that a great sensor yet it is in ~ a range that ns would expect to watch from experience. My assumption at this suggest was that the sensor was probably not the issue.

The brown wire meanwhile showed an open up circuit to battery ground. Once I looked in ~ the wiring diagram it plainly states the this cable is attached come ground. I confirm the brown cable a couple of inches above the connector and found the floor signal present.
I provided this tool to release the plastic clip that organized the terminal in place. There was additionally a white hopeful assurance clip top top the end of the connector that I had to eliminate first.
I spliced my new wire come the initial brown cable at a practically location.
