China junk
Does not fit 2005 Crew cab Sierra SLT 2500hd with AC and dual climate control. It's a big job to get all apart and realize that you have the wrong parts. Also made in China. Disappointed

2004 avalanche oem replacement
Fit perfectly 2004 avalanche. It came with all the gaskets. The other ones did not fit and did not have the gaskets

Perfect fit and good quality.
Connection was just a little off but it did fit. After install it is not leaked as of yet. Seems good quality.

Does not fit gm Sierra truck as described in vehicle application.
The item itself was fine. But the parts selector was wrong. This did not fit my 04 gm truck with center console. I'm not sure what this fits.

Waste of time
Bought top end of pricing for quality. Waste of time. Part is used. It has been repaired and boxed shipped made in China. Not Delco
