2004 Suburban Autoride System

thardy · January 31, 2011

This past weekend my father and changed out the rear shocks on his 2004 Suburban. We got the OEM remanufactured shocks from Arnott Industries. When we hooked everthing back up, the suspension compressor did not inflate the system. The solenoid clicked like it wanted to start, but the compressor never started. I had recently replaced the compressor on my 2005 Tahoe (I purchased it from Suncore industries out of Florida. I need the dryer, as well as the pump, and Arnott does not sell the dryer). So, I pulled the compressor off the Tahoe and put it on the Suburban to see if the compressor was also bad. The solenoid on the compressor clicked again, but nothing happened. I then hooked both pumps up again on the Tahoe. Both pumps worked fine. It appears that the pump is not getting a signal or power to turn on. We checked and tested the RTD Fuse under the hood and it was fine. Any one have any thoughts?

Thanks.

Connector 450. It's the big dock and lock connector that is attached to the outside of the right rear frame rail, behind the rear tire. Seen a bunch full of bad stuff. That or bad power and ground supply to the compressor. The click noise is the exhaust solenoid, most likely, and if that is clicking, the pump should run.

Thanks a bunch. Is the connector on the Driver's side? Is this where the power comes off for the pump?
