You can't tell what the problem is just by the presence of the "check engine light." Many sensors can set off the light. You can connect a diagnostic analyzer to the vehicle and it will spit out codes that you can look up to see what the problem is. That is what most shops do, or you can buy an analyzer and do it yourself. It may be harder to find one for a 1987 car though

After changing alternator in 95 cadillac deville the heat doesnt blow at all

The alternator does not have anything to do with the blower fan for heat. You may have unhooked a wire by mistake, or you have a blown fuse. God-Bless!

Where is alternator located on 1996 cadillac deville? how do you replace alternator on 1996 cadillac deville?

The alternator will be located in the front of the engine on the drivers side. To replace it you must loosen the idler pulley and remove the serpintine belt, once the belt is off you must unhook any wires goin to the alternater and then there are two bolts at the bottom of the alternater holding it in place. Remove those and the alternater is loose then it may take some jockying back and forth to get it out. Obviously at this point the new one can go in the same way the old one came out.

Horn wont shut off when installing battery on a 1987 cadillac de ville. how do i get it to shut off?

I would check the steering wheel under the button cover to see if there is a short in the wire to ground there.

One can disconnect the wire to the horn, but this means that it won't work for state inspection, if you have that in your state.
