question on the info center concerning the rear airshocks, last weekend towing i never heard the compressor turn on or release
however i see no error message in cluster, should i ?
i can search how to diagnose if the comp is bad etc but i thought it should let me know if so as well ?
i use the #2 fob, do i need to start it with the #1 ?

thanks in advance

The compressor should work no matter which driver preset is used
You can jumper the relay for the air shock compressor and see if it kicks on

Likely it is throwing a code but the system isn't throwing the message in the dic to let you know something isn't right

My shocks were blown and the compressor blew a seal and had water in it and was rusted tight and did not throw any codes in any module or display until the lowering solenoid opened and that finally threw a code and the display said Service Ride Control.

pulled/checked the 3 fuses, ok and started looking for relay, where is it ????? didnt see it around batt or around steer pump area as ive seen in videos
then turned key on and a few seconds later pump kicked on....i sure hope this isnt an intermittent issue as sometimes its a pain unloading boat/trailer

The relay is under the hood next to the fuse box(towards the engine)

I would get the system checked with a tech-2 as it could be a bad sensor or the compressor
