Question A/C 93 Suburban

The A/C works ok as long as the engine is under a load. When I sit at idle it doesn't blow cold. Any advice ?

Low pressure, perhaps a cooling system issue. Time for professional service.

Low Pressure ? Can you elaborate a little.

Could be low on freon (low pressure). It could also be something simple like the fan clutch slipping, or if electric fans, the accessory fan may not be coming on. If this is the case, your head pressure may be developing to such high pressure that compressor damage can result. It could be other things as well, but these would probably be the most common.

Again thanks for the advice.
