You really need to get a set of manifold gauges hooked to it. those little gauges that come on a can are not accurate and are often very wrong. you really need to be able to see both the high side and low side to diagnose.

Is the condenser cold to the touch or hot?

It’s an SUV, sometime the rear controls can affect how the front blows cool air.

I have a 2001 Yukon XL for an employee. If the rear controls are off it won’t blow cool air. There is a connection behind the rear right plastic panel when dirty will stop the rear from blowing air.

Might want to read that again. Cooling system generally refers to the engine cooling system, water pump, radiator. An a/c compressor would fall under the heating/ac system.

Depends on the warranty company on how they word it.

checked the rear controls....didn't touch the condenser but the lines are hot

:facepalm:

I’m sorry, I meant to say “accumulator” instead of condenser. LMAO

I don't know what that is.....

I double checked....it says cooling system and air conditioning so yeah, cooling system is not AC but AC seems to be covered.

So I got down and looked at the compressor while it was running..the outside is rotating fine but the front has a bunch of tar looking stuff around the edge and the middle part is barely turning at all. Not sure if that's normal or not but it doesn't look normal....

Should be mounted near the firewall and it’s the size of a jar of spaghetti sauce or large beer can with several lines going in and out.

Here is a pic of a Yukon accumulator.

The AC accumulator is a metal canister that acts as a filter for the AC system. It is filled with desiccant, a moisture absorbing material.

Of course Sauto is out tonight. Dude would have had it pegged in one post while I fumble around all over the place.

Heh, yeah he was here earlier but he's not on right now.

Okay yeah, it's all hot. All the lines are hot. And when you look at the compressor head on, the inside is barely spinning even though the outside is cranking away.

The part that really stumps me is when I have it on just vent it blows just hot air. You'd think the cooler air from outside would be more of what I feel with the thermostat set at 68 or so.
