CHK SUSP light is on... Need Help!
My Chk Susp light come on this morning on the way to work (I have the load leveling system on my 99 EB Expedition). I checked the switch, and it wasn't accidentally kicked off, and now the truck sits pretty high in the back... well, higher than normal. Any ideas as to what this could be? I have not heard the air compressor cycle on this morning.
