Suburban Autoride Questions

[dac675]

I am having problems with the autoride and self leveling suspension in my 2000 K1500 Suburban and I was hoping someone could lend some advice. My rear shocks no longer level the truck, but I am not getting a service message on the dash either (shouldn't I?). Regardless of how much weight is in the truck and how much it sags, the compressor does not kick on. The previous compressor was seized, so I replaced it. The new one does not kick on at all either (if I power it directly to the motor terminals, it kicks right on). I checked the RTD fuse and the post 1 fuse, but these are both good. Does anyone have any suggestions where to go next? I was looking to check the relay, but I cannot find it. It is not in the main fuse/relay box, and I do not see it in the engine bay. Can anyone tell me where the relay is so that I can jumper it out and see if the pump kicks on? Any help would be greatly apprciated!

 

Thanks.
