When l start my car sometimes the rear suspension lowers down. l pull the fuses and reinsert and then it works fine. While sitting the bags stay up fine so that tells me it not the bags. Can l just disable with the switch in the trunk and see if the bags stay upor what do you think would cause this?

Yes get the car at the height you want and just turn the switch in the trunk off. l have a 98 Continental l have had since 99 and l never keep the air suspension on. If l have passengers or a load l turn it on but other then that l keep it turned off and it never loses air and l been doing this for many yeas now. Yours should not lower when you turn the key on it should raise up but if you just turn it off you wo not have to worry about that for now.

the switch in the trunk is only for when the car goes up on a lift , there must be a bad relay or something , sounds like a easy fix , ask a lincoln tech. l have the same car , never had a problem like that
