Replying to: mcdaddy1956 (Aug 18, 2009 2:01 pm) mcdaddy,   I was wondering if this fix is still working for you. I'm about to buy an '04 yukon in phoenix and a/c is super critical. I experienced this prob on a test drive yesterday. was gone after a restart but won't always be able to pull over. If good, can you give me some clues on harness/colors so I pull the right one??...   thanks,   Joe Replies to this message: needlenose (Oct 02, 2009 12:16 pm) tidester (Oct 02, 2009 3:30 pm)

Replying to: jbast (Oct 02, 2009 11:51 am) Finally solved my a/c problem; tried a several things, like removing battery terminals and holding them together to drain residual voltage from processor, etc. Ended up that after removing neg terminal and putting it back in place, I turned on key, BUT DID NOT START THE YUKON. Waited a couple of minutes to let it re-program itself, then started it up. At that point, all is well. Hope this helps!! Replies to this message: tidester (Oct 02, 2009 3:30 pm)

Replying to: needlenose (Oct 02, 2009 12:16 pm) I am glad that worked out for you and thanks for sharing.   One minor point, however, you did not remove the battery terminals. You removed the battery cables. That's just so no one tries something dangerous.   tidester, host SUVs and Smart Shopper
