Airmatic Compressor Fuse or Fuse Block
Hi All,
Searching the older threads I get conflicting information if there is a fuse in the right rear or left front fuse box or if there is a fuse block in the right front box where the jumper point is? I have 0.0v at the compressor connector when I turn the compressor on via Xentry. The relay clicks and shows ‘ON’ when tested in Xentry….so trying to get the low hanging fruit first.
Thanks!
Myles

I just dealt with this on my 2014. It blew the 60 amp fuse in the "Fuse Box". It is located adjacent to the main battery and is stuffed between the engine isolation wall and the shock tower. You cannot replace the fuse as it is buried inside the box. I ordered a used box off of eBay, and a new aftermarket compressor. My assumption is the compressor somehow locked up and caused the over current condition. I also ordered a new filter that cleans the air that gets sucked into the compressor for inflation of the air bags. It was a fair amount of work, but really wasn't that bad once I got past the diagnosis. I have Xentry, and the test I did to confirm compressor operation indicated the compressor was not firing, which was due to the blown fuse. Pic below of the blown fuse. Let me know if you need anything else.
Regards,
Joe
