No Windows will work on a Cadillac Deville - DeVille Cadillac Cars & Trucks

Not cold,but fan will work the same but the windows will come down so fast.

try to replace the battery??

and chek all the connections!!

When my window stopped I pulled out the driver side controls , removed all the wire connections, cleaned them , then put them back in and everything worked fine.

On this website you find fuse box diagram and description for Cadillac DeVille (1997). Maybe it helps you

If none of the 4 doors work check the relay for no fuse runs it. It is attached to a breaker although that breaker runs to the windows as well

start looking at the relays, computer should be the last thing you look at

blow fuse or window switch is bad

it sould be under the back seat but i have fixed a few caddys where the back windows wont work it was the wires in the door jam in the rubber boot the wires broke in half from opening and shutting the door

i was toli d its the regulators for all windows on cadillac when they come down usually, but could be differant. i was told it would cost anwhere from regular garage would do it from about 75 a window plus labor. a cadillac dealer wanted 400 plus labor.just trying to help out . good luck

if it is not in the box under the dash to the left of the steering column then check under the hood on driverside near the front
