Where is the outside ambient temperature sensor located on a 1998 Cadillac Catera located

SOURCE: 99 cadillac de ville

the coolant temp sensor is at the rear of the engine and is a "bad word" to get to. the 3 relays are at the bottom,under the fans. if you remove the driver side fan out of the way( 2 10mm bolts holding the fan) you should have good access to them. they do have locks on them and may be tricky to unplug. there is a 7/16 nut holding the relay plate down. remove and it should be easy to remove them.

Maybe this will help . although this is from a 1997 Caddy.

On my car, which is the same as yours, it is located on the manifold top back left. Pictures in the book just show it on top.
