96 Town Car Air Ride 127,000 miles

I have a 96 Town Car purchased a month and a half ago, and the air compressor kicked on all the time, but you would see the car go up, then the light came on and I heard the compressor going but it was not raising up, started the car in the morning and it did not come on as normal so I checked the fuse, it is blown. However I did not replace my fuse I have left it alone and I turned the switch in the trunk to OFF. It is currently not all the way to the ground its sitting just a little low in the back. So to see if the compressor blew because my bags are leaking I am driving it around, so far it looks the same, its been on hwy, bumps, stop and go traffic and bounced up and down by hand. So I have a feeling that the bags are fine. I am alright with simple repair on my car (bolt on bolt off) and can handle some things but I do not want to jump into something I can not handle so I need to know detailed exactly what I will be going through to fix it, can I buy my own compressor (if so which one) and install myself or is it hassle and should be taken to a mechanic. I also want to keep my air ride not swap for regular assembly. I have read a little bit and some people say that it all could happen from something as little as leaf in a line, so how do I check my system well enough for my own peace of mind and that I didn't fix a snowballing problem. Thank you I also bought this 25.00 dollar chilton book, all about lincolns that seems to just decided to leave out the whole thing on waht to do if (trouble shooting) air suspension light comes on, and about the air compressor (FORD go figure!)
