Rear Air Suspension stuck in full up - HELP

[ssheftel]

I have a 2005 V8 with RAS. I'm on a trip and it is stuck in the full up position. Is there a way to disable the system? And to get it to come down to its 'normal' height?

I went to a Toyota dealer who was less then helpful. They wanted $900 for a new height switch and RAS ECM I will have it looked at by a non-dealer when I get home.

Thanks for your input . . .

The only way I know of is to open a line to let the air dump out. You can pull the fuses. IIRC, there's one under the hood and one in the fuse panel. It won't let the air out but it will stop the compressor from adding more.

If using the console control won't lower it, it's probably not the height sensors. I had the same issues a while back and the dealer replaced the tank reservoir and compressor. My 2003 had an issue with water getting into the tank and fouling the valve that lets air out.

I had this problem after having a bit of fun it the mud my ras got stuck at full extension which made the shocks bottom out over bumps.

Anyways my problem is that the "link" (see attached pdf Pg.25-7 Fig.C99156) that connects the sensor (far left in picture) to the ride control sensor link broke. So when it broken the sensor got stuck in one position so the compressor kept filling the bags because the senor wasn't telling it to shut off. I just got under the truck and manually put the sensor to a roughly "normal" position.
