No power to air compressor???

Just finished replacing front strut. Now no power to air compressor. Pulled fuse 108 for air compressor prior to doing job. All back together and no power at fuse...

Any thoughts?

Probably need a new air compressor. Does any lights go on indicating that there is a compressor malfunction?

Now just one GL450 with EORP.
Check for a disconnected or broken level sensor...on the wheel you changed the strut.

I doubt you bricked your compressor by changing a strut, but it’s possible you’ve disrupted the level sensor signal from that wheel so that the compressor never gets the signal to come on.

I can't imagine how you could have broke the compressor - and I don't think not having power at the fuse equates to a bad compressor?

I'm a mediocre electrician at best, so maybe someone can clarify... the underhood fuse for the compressor comes BEFORE the relay, right? Meaning, if the engine is on, there should always be power at the fuse, right?
