I bought 1 owner 2003 Town Car Signature Premium. GREAT shape. Only 68,000 miles. The battery terminals were corroded so I cleaned them this past Friday. When I put them back on I had to jump the battery. After that, my driver seat controls stopped working, the mirror controls stopped, the air suspension light on the dash stays on and the power steering is almost like manual steering. All 4 things share the same fuses and fusible links. (a couple on one set and a couple on another). I bought $40 in fuses and fusible links Saturday at AutoZone but it never helped. New battery also (old was bad). Still no luck. I tested the fuses and links and they are showing good BUT I have no way of testing the circuits to them.
RepairPal Certified shops can diagnose and repair your 2003 Lincoln Town Car. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
This type of problem is usually caused by 'reversed battery polarity' at some point during jump starting or battery replacement:
Using a 12 volt test light - TEST each and every fuse you can find - (including the 'maxi' fuses) - test light should light up when both sides of each fuse is touched..
I am not aware of the 2003 Town Car having *electronic power steering*" - therefore a blown fuse should not have any effect on the steering.

Ok, ''possibly'' it has affected the EVO (Electronic Variable Orifice) - however I still highly recommend reading the information associated with the link I posted.
Good luck with it!
