Just had my old Air Compressor replaced 3 weeks ago and got new hoses from FORD. Everything was fine Expy ran smooth as ever. Then I added 2 12" Subwoofers in a box. Now my suspension is out again. Cant hear my Compressor turn on....

HELP!!!

 

Are you using your factory radio as your head unit? Does your amp still come on after the air went out? If the answers are yes and no respectively, check to see what cricuit your remote wire is tied into. Could have blown that fuse. Also could be a complete fluke too. Give me some more detail to the install. I manage a custom audio/video shop. Good luck.

 

My radio still works and the amp still comes on. Yes I am using the factory deck. Put fuse from battery to amp as usually do with subs. Not sure if weight of box + subs caused something but am unsure why Air Compressor stopped as it is 3 weeks old.

Checked Air Compressor fuse near transmission fluid. Still seems good. Possibly blew another fuse that has to do with compressor? Wiring? Damn this Air Suspension is frsutrating. Feel like I have Hydraulics in the back....hahah

 

Itmay be a long shot, but when you were installing the sub's, could you have shut the suspension off accidently with the switch?

 

You mean the switch under the passenger dash? No I checked that and turned it on and off a few times. I removed the subs and box last night. Still no difference. No noise from Air Compressor at all.

 

Hi,
After successfully solving a "check suspension" light and no compressor action by replacing the front height sensor, I'm back with another problem with a similar effect.
I solved it briefly by disconnecting the battery. It must have caused the LLC computer to reboot.
This is my wife's Nav and she never has a problem but as soon as I drive it the suspension acts up.
I can repeat the problem, The Nav has 2 settings on the door for 2 different driver preferences( mirrors, seats, petals).
When I hit my prefernce (#2) the suspension stops working.
