Air Suspension trouble.
my LX 470 is 2004 model. Recently started having issues with AHC
1. front goes down in split sec after parking the car. Next morning it goes up sometimes and stays low otherwise.
2. Everything good while rolling out from the parking but soon looses height and the drive turns rough.
3. All the 3 functions Up/N/Down are working fine while the vehicle is stationary.
looking forward to your guidance. Thank you
George.

First, there should NOT be any air in the suspension as it's hydraulic...reservoir is on the passenger side inner fender...a white tank-looking thing.
How long has it been since the AHC fluid has been changed? Looking at the reservoir, describe the color of the fluid as best your can.
Grab a piece of masking take and a magic marker. Stick the tape on the reservoir new the graduation scale. Warm up the truck, select "H" on the AHC selector switch. Once the truck is in "H" position, mark the tape at fluid level. Now select "L" on the switch...when the truck finishes lowering, mark the tape again with at the fluid level. Count the small graduations on the reservoir. You should have a minimum of 8 small graduations between high and low.
