Speedometer Stopped working.

I was playing around still trying to figure out why my interior lights still were comming on. I don't know why but I was playing with the fuses and relays in the power Distribution box and another box onside of it with 2 relays. I just pulled them out and pushed them back in. To see if maybe one was loose. Now when I went back in the car my speedometer is not working on my 2000 marquis. Im just going to bite the bullet and send it to the shop for the lights. But I would like to get the speedometer working before hand. I learned my lesson its not worth fooling with it if I do not know anything. Any help, Thanks

Disconnect battery--clean post and reconnect. Check for a ground problem. Check battery voltage-car off and running.

Battery Is good. Did what you said. Cleaned them really good and reconnected it, and its still not working. Is there anything else you all can think of where to look.

thanks in advance

Hey shady. Re check all the fuses you pulled and see if maybe one is in the wrong place or it has blown.
