Re: 2003 navigator suspension problems
I'd get the air bags and lines inspected for any leaks. I drive an '04 Freightliner with full air suspension and have never lost air pressure even sitting outside in -20C weather for a weekend. Perhaps a fitting has come loose and the cooler weather will shrink anything made of rubber. When the temps rise the hot air expands the system sealing any cracks so it will seem to work normally.
