I've got a 2011 GMC Sierra Denali that ever since I've purchased it its been difficult to turn. I put in a brand new AC Delco pump, and it helped slightly, but its still noticeably harder then I think it should be. Cold or hot, it remains about the same Is there any way to test for pressure or is there any sort of adjustment that can be made on the steering box itself, or do I just have a bad rack? Thanks for any ideas!

Soon as I jumped the relay I heard the clutch engage. A/C worked. Waiting for scanner to show up to read the body codes. Thanks for the help!

@carnau Thank you for this info, I will give it a shot. Will a regular scanner typically not read body data?

Have a 2011 GMC Sierra Denali, cannot get the A/C to work. 1. Tried to do a recharge with a bottle from Autozone. Gauge went into the red, signifying there was other issues. 2. Discovered when I turned on the AC, the clutch would not engage. Can spin clutch freely by hand when truck is off. 3. Both the fuse and the relay tested good, swapped them out with new ones just to be sure. No change. Can someone point me in the right direction as to what I should be looking into next?
