Having problems with the AHS system. Blinking OFF light and car height stuck on low. Have removed old fluid and added new fluid bought at dealer. Bled the system and no results. Have been checking all electrical connections and noticed that pump in not running. Replaced the AHS relay at fuse box in engine compartment, pump still does not work. Wired pump directly to the battery and it runs, but height of vehicle does not move, nor does the fluid in the reservoir change. The pump as of right now does not get any electrical current to it. Removed and inspected the front sensors they look good, but problem still exists. Have read there is a AHS pump relay. Does anyone know where the relay is located? I think I have to find out why I am not getting any electrical current to the pump first.
