Air Ride

Checked resistance of exhaust solenoid. And get 17.4 ohms.

When you disconnect the level sensor, and jumper "A" white to "C" black, the click you hear is the solenoid clicking, not a relay.......since you don't hear a corresponding hiss with the release of air, it looks like the solenoid is not working.......the reason why you don't hear a "click" when you reconnect the harness, right away, is because the level sensor has a built in delay function, that buffers the signal...if it didn't have this, with every movement of the vehicle, the ex solenoid and compressor would be constantly working, against each other....

Ok. Took the compressor out.

Took a reading of just the wires going to the solenoid on the compressor, and it is stuck open. (ie the ohm meter was not able to get a reading).

Based on all the info you and this forum have provided me, I've ordered a new compressor.

Too bad, I actually took the solenoid out with some work. But putting a new one in looked to be fairly simple.

While I had the solenoid out I tested it again with the meter. It's definitely dead.

I had checked the wrong solenoid in this step. I had measured the resistance of the solenoid inside the van for tire inflation. My bad.

I'm also thinking I was tripping that solenoid, since a bench test with a 12 volt battery on the compressor solenoid did nothing.

Yeah, have seen those exhaust solenoids fail......like I said, unfortunately, they are integral to the compressor and not replaceable.......you'd think they would be.....

Yeah.. You'd think.

Just wanted to say thanks for all the help and assistance.

Installed a new compressor assembly, and we are working great again.

Glad you figured it out. Is the part serviceable, or did you get one from a donor?

So that's what the compressor looks like inside. Not a lot to it really.

Was curious to know, but mine is '99 vintage and a lot more corrosion on the brackets and bolts that hold it on. If it falls off, I'll do an inside look like you have done. Thank for sharing.

Oh and hey, your bench looks a lot like mine. Are you right or left handed? Just asking. I'm a lefty.

The solenoid is serviceable on this pump. As you can see here:

It is externally removable.

FYI. I'm right handed, and the brackets etc only look so good cause I painted them.
