I enjoy watching your videos. You are accurate and detailed. We just had an 02 Tahoe w/ dual air in the shop last week for a/c inop. Belt was broke. Knew pattern failure of slugging compressors wiping out and told them before we put one on. Had to see what the pressures were. Belt on with correct charge found tensioner noisy on first start up. Slight flutter on high side as well. A/c locking up then freeing. Found a TSB pertaining to this. Was very interested to see that the TSB also says to install filters in the system. System was about 41 deg.F, which is pretty good in a 90 deg. F shop. I personally think that inline filters just before and just after the compressor should be installed as OE, not as an aftermarket option. The sensors that are already in the car will give some kind of clues as to whether they are clogged. Some cars have reminders for other maintenance items besides oil changes, why not on a/c filters too?

did yall listen good. changed the pulley and the belt because wanted to eliminate that from the noise making. then used the scope on the compressor to make sure that was where the noise was coming from.... hmmmmmmmm people people people.... the scope should have been used first. now the customer had to pay for the tensioner and labor and the belt

No, not at all. There is only one compressor, so if you have cold in either the front or the back but not the other, then the problem has to be at the point where the compressed gas expands and makes it cold. That would be the expansion valve or orifice tube. Depending on which you vehicle has.

MaryAnn, I'm sorry to hear about your trouble. It's a 2015 and therefore I assume under full warranty. From what you have said I can only think that the dealer simply made a guess and replaced parts without any diagnosis. A/C is not that hard to diagnose. They should be able to figure it and and if I were you, I would NOT accept anything else than a complete fix. The fact that it does get cold but only for 10 mins tells me that the mechanical aspect of the a/c is ok. It must then be a "control" aspect that is not allowing it to engage. Hope this helps
