Here is he diagram I will be using.

The ECM controls the ground to the clutch relay that energizes the compressor clutch.

Do you have access to a scan tool to see if the ECM is getting an AC on command from the HVAC and if the dual pressure switch is grounded?

Hello again Chris here,

  • I am contacting you because the post has not been closed out/completed.
  • It appears you were not pleased with my help.
  • If more assistance is needed, reply and let me know, also let me know what it is you're needing to be pleased.
  • This post is coming up on the 7 day mark where it times out. When a post times out, that means it's no longer on my active list (you reply and I never know it.)
  • You have already paid the fees to get this question answered, and I do not want you to leave having paid for something that did not meet your wants/needs and myself not receiving a feedback selection from yourself.

Thanks Chris

I do not have access to a scan tool. Is that what alto zone can do. ? Your response was a little vague to me
Expert:  Chris (aka-Moose) replied 2 months ago.

The auto zone tool can only get engine codes. A more sophisticated tool from a shop is needed.

Sorry you felt my diagnostic help was vague. I have to be vague to determine the customers skill level to see if they can even to the diag and repair they are wanting to do.

Have not had a chanc to have Ecm checked. Any suggestions other than that ? Thanks. Dave
Expert:  Chris (aka-Moose) replied 2 months ago.

Without testing any repairs would just be a guess. If you want to try a part, the best choice would be a replacement dual pressure switch.
