1994 Cadillac Seville

If the wrecking yard has a 94 SLS or STS, that would most definately work. I would guess that 93-96 or maybe even 97 would work, but that is a guess. The column did not change all that much through that body style. You need to be aware of column, or floor shift options. STS and SLS should be about the same however, if there are differences, it would most likely electrical connections. One other concern, there are 12-15 possibilities of VATS key codes. Your vehicle has 1 of these. Chances of you getting a column with the exact theft code as yours is slim, wrong code it will not start. You will either have to transfer your ign lock cylinder, swap the VATS module with the one from the donor vehicle or, knowing your key value, have a new key cut with the pattern of the new column.
