Hello, My 2013 Tahoe (with Towing and Air Load Leveling System) seems to be having issue with the load leveling pump running more than it used to. It now runs for 20-30 seconds every time I start the vehicle, and sometimes after driving for awhile. When I hook up a trailer, It runs for a long time at start up, and frequently thereafter even while driving.
I suspect that I've got a leak somewhere but don't really know how to check for the leaks beyond spraying soapy water on everything. I am not getting any warning lights, nor any codes from my code reader. I'm here asking for guidance because I've not been able to find any good information on this online in terms of how to check for a problem, or in helping me narrow the problem through experiences of others (ie: Everyone is seeing that the shocks leak, or a fitting loosens, or a line splits, etc). Though I do see a lot of information on people having issues with the load leveling system in general.
Can anyone point me to a forum post, a different online resource, videos, etc? I'm completely comfortable removing, replacing, troubleshooting, but have not dealt with the air leveling systems before, so looking for some guidance to get started and don't want to overlook anything simple..
I suspect it is just a slow leak somewhere that is made worse under heavy load... but would like to get this addressed. Thanks in advance.
