I have a 2005 GXThanks Dan. Found it! I was looking in the big box that has most of the fuses and relays. The AHC relay is is a separate sealed box attached to the side of the main fuse panel.
Only 1 relay in the box.
Just got OME
I have removed Air Suspension relay and TEMS and two fuses from the engine compartment, but dash is lit up. Put back TEMS, and all it does it bring on the OFF light blinking too. What do do? Is Zero point calibration the answer?
