Suspension Woes

I thought in the big bunch of receipts it had had a new compressor in its life, but it doesn't seem to have. It's a 2005 V8 with 156k on it.

All was fine until I hit a bump and the dreaded yellow suspension warning came up

It had blown the 60 amp fuse, so replaced it after a week or two of running around - pumped up to normal height and then blew the fuse again

Ran around fine for a couple of weeks, slowly sinking

Swapped the relay and replaced the fuse

Now it's stuck in access mode height. Selecting normal does the following

Compressor runs for a couple of minutes and then turns itself off for 3 seconds, powers up for 3 seconds and so on. Guessing it's over heating? Turned off at that point. Throws the rising slowly warning, but I doubt its actually going up at all

Current codes are

U0421-94 ATCM .. Invalid data from ride level control module
C1A27-14 RLM ... Compressor circuit
C1131-92 RLM ... Air supply
C1A20-64 RLM ... Pressure increases too slow when filling reservoir
U0132-98 VDM ... Lost communication with ride control module

Is it time for a compressor replacement, or are there multiple things here?

Assuming there are no air leaks, then its compressor time, especially if its blowing the 60A fuse

Mike.
Is that the common reason for 60A fuse blowing ?
The compressor? Or is it shorted wiring ?
