2013 GL450 aromatic relay Location

I have searched high and low for the location of the airmatic relay. All of the diagrams shows the fuse locations but not the relay. I am replacing the compressor and relay. Any help would be appreciated.

Can someone indicate the actual relay for the airmatic on x166? Thanks

Hmmm, an aromatic "airmatic", perhaps lavender...

Haha!!! Yes, the Airmatic relay. Autocorrect got me.

i had a collapsed rear airbag, so I replaced the bags but still had a malfunction light. So, I purchased a new compressor, filter, airmatic relay and 40amp fuse. The compressor and filter were a very easy install. I replaced to Fuse but for the life of me I can not find anywhere the location of the airmatic relay. I pulled the relay at the “M” location in the fuse box with no luck. Malfunction light still comes on.

i just need to know which relay is the airmatic.

Aromatic relay

The relay is the grey color on top of the fuse box. Just below the Red (+) wire and the the left of the two big fuse. Btw one one of the big fuse is the Airmatic fuse also.

I am trying to replace the rear suspension airbags with Arnotts. however, I can't get the 40 AMP orange fuse out. The transparent plastic cover popped off when trying with a needle nose plier. The gray relay looks easy to remove. Can I do that instead. This should disable the compressor correct? Trying to move the plastic tab on the fuse is tough, but even after that, I think any more pressure would break the orange plastic housing around the fuse.

Thanks.

Might have some light corrosion underneath, try spraying it with a Contact Cleaner of some sort.
CRC makes a bunch of electric cleaners;
CRC® 2-26® Multi-Purpose Precision Lubricant,
CRC
® Contact Cleaner 2000® Precision Cleaner
CRC
® Lectra Clean® Heavy Duty Electrical Parts Degreaser

Or any manufacture of electric cleaning products, this is just what came to mind since I have a few of those in my garage.
