digital display stopped working???

HEY-
I bought a 1990 lincoln towncar, and finshed installing a new cd player and spkrs, amps, and sub.......but, when I was completed with the job the digital display which has the speedometer, gas gauge, temp....etc., no longer worked?? I was extra careful not to cut a wire or anything I might need. I have installed this system in my passed 3 cars without a hitch. I also checked, twice, all the fuses under dash and under hood, but none blown??
can someone hook-me-up with fixing this issue??
Thanks a mil for your help!!!!

well,after further investigations and more issues with the display related issue.....a few days after the digital display went out, the attenna would not go up and the ass-end of the vechile, mostly on the right rear, was sagging really low. The towncar has an air suspension rear end (suppose to be for towing) and the device that delivers the air to it is housed under the hood. Now, follow me-
I re-checked the fuses under the sterring wheel column and found a 15 amp fuse that you would barely notice being blown, that was slightly blown. I replaced it, and by god the digital display and the rear end came back!!!!!
Fuses are hooked together to operate different functions at the same time???

go figure?!?!??!?!?!

Great Work !!!


Nice that everyone jumped right in to lend a hand :banghead:
