I would appreciate any help on this. The pressure switch is leaking, and I am an amateur mechanic if that LOL. I have looked for video's for help and could not find anything. I had to change the wheel hubs a couple weeks ago, and those video's helped me.

 

I have a 05 Grand Marquis and my pressure switch went out as well. It's not a big deal to swap it out. If I remember correctly it has a wire that needs to be taken off. Then it's just a matter of unscrewing the old one and screwing the new one in. It's a common problem with this car. My dad's 04 had the same issue. Hope this helps.

 

Ty for your help
