Air Dump Switch not working and bags won't deflate
« on: January 25, 2025, 06:34:53 PM »
Main Manual Ball Valves open.  Bags on Driver Side will not deflate.  Air Dump Switch did work a couple times and then gave up.  I'm lost.

I've' found a Bosch Relay for Air Dump.  Will change that out I guess?

Relay was the fix.

This timely to me.  I am not sure my air dump switch on my 2001 Beaver Marquis Amethyst is working. Could you tell me where this Bosch relay is located?

Thanks,

Mike
The relay will be in the electrical bay first bay door on the driver's side
There should be a legend on the wall or door in that bay that tells you what each circuit breaker and relay is.

The air dump button in my 2002 Marquis, located next to the transmission controls, only works when the ignition switch is in the on position.  The leveling system will dump the air regardless of the position of the ignition switch during automatic leveling.

On my 1997 Patriot the dump valve push button is mounted beside the ignition switch on the dash and only works with the ignition in the accessory position.

To reiterate, I found the Relay and it was the issue.  Now I have a 25 year old air dump valve that's stuck open.  I've ordered all four replacement valves.
