I have a 2000 montana and have been attempting to replace the auto level suspension air pump or compressor, I can seem to get to work I used a lighted tester to make sure there is power at the main connector had the new used pump tested at a local repair shop and works great, they told me to check the relay that the other connector plugs into so I bought a brand new relay at 35.00 bucks came home plugged it in and still nothing works. any ideas out there
