Tony and I just spoke, let me summarize for those following.

So first order of business is to determine if this is an electrical or pneumatic problem.

Step one, lay under the front left and stare. After all, lots of contortions, wrenching, and coach yoga where all the wires and air lines are located when you are working on the front left.

Step two, put coach in level mode, and see if raise solenoid magnetizes. If it doesn’t then pursue electrical troubleshooting. The horn beeping may be clue, or it may be a distraction.

Step three, assuming the raise solenoid activated in step two. Disconnect the air line from the six pack to the ping tank. Cobble a fitting on the air line to provide air pressure from an external source to the ping tank. The bags should inflate. If not look for a loose or pinched air line.

Step four, if the external source inflates the bags, then activate the raise switch, air should come from the back of the six pack.

There are a couple of gotcha’s. One, the coach is up on jack stands, the height control valve will think the coach is high and will not inflate the air bags in travel mode. Two, best to provide air pressure with an external compressor vs with a running engine, just because you can’t hear anything with the engine running.

And it’s not clear to me, if the entire system is not functioning properly after the horn beeping, or just the left corner. If the entire system is inop after the horn beeping, then it’s an electrical issue.

Good hunting!
