Re: CHECK AIR SUSPENSION!!!!
While waiting for the coil springs to come and being tired of riding on the bump stops to and from work (60 miles total) I...............
(1) pulled the compressor and leveling sensors out completly and
(2) made the air springs like air shocks.
For $6.00 I bought a stainless steel 1/8" T and spliced it into the following lines, one each to the air springs and one to the air fitting in the rear of the truck that was normally used to fill tires/toys. Now that fitting is used to fill the air springs to the desired pressure. I have approx 65 PSI in them and the truck sets up high.
This should carry me over till the coils show up, hell, I just might wait till summer gets here to change them out.
Just one question, how does a person get the "service air suspension" warning to turn off now ? figured that with the suspension module removed that it wouldn't come back on....wrong

Re: CHECK AIR SUSPENSION!!!!
Screw having the air ride, went with the coils, no more "Service Air Suspension" warnings in my life  Did get a little carried away taking it apart

Re: CHECK AIR SUSPENSION!!!!
P.S. I think this may have been the problem. would have changed it if I knew it was stuck up and under the drivers rear fenderwell  Restricted air flow to the compressor, caused it to heat up and shut down til the next start up and then all over again.

Re: CHECK AIR SUSPENSION!!!!
is that the filter for the compressor... question.... did you see any kind of a accumilator, like a catch-can, on the compressor?

Re: CHECK AIR SUSPENSION!!!!
yup, That is the inlet air filter :-(
Not sure if it is called a accumulator or not but that may be it in the center of the pic towards the bottom. (black canister)
Later, Ed
