I also posted this in the suspension section, but being a 2nd gen, I thought I'd see if I can get some assistance over here.
My '05 Expedition Limited has factory air suspension. I'm the second owner with 186K miles. Usually it rides awesome. This is the first winter I've owned it and living in Houston, it doesn't always get below freezing temperatures.
However, when it does, the suspension doesn't want to inflate. I can hear the compressor kicking on. It all sounds normal, but it doesn't inflate and rides as if it has worn out shocks. I will also get a "check suspension" warning after about 15 minutes.
Once again, this only occurs when it's at or below freezing temps. I've tried letting the truck sit for ten minutes to see if radiant heat from the engine bay would heat up the compressor area - nothing.
My first thought is the possibility of condensation building up and freezing in either a supply line or ice causing a purge/drain valve to stick open.
Has anyone had a similar issue? If so, what was the fix? I did not see any posts with similar problems when I searched...but I'm going to try a few other keywords and look more.
Thanks in advance!
