Cadillac DeVille

There may be a short in the relay between the door locks and the switch. First check the wiring between the locking mechanism and the switch, if that check out it may be a short in the fuse itself.

Yeah i got some on my 92 caddy so that must mean that u can all i had to do was get low profile tires 230 35 22

E30 means the Idle Speed Control motor rpm is out of range, E31 is a shorted MAP sensor circuit. They are probably both related to a bad MAP sensor so replace it first.

Here's the story on the P0410:

The AIR pump adds air to the exhaust stream to lower emissions. It does this by taking in outside air and pumping it through two one-way check valves into each bank of the exhaust.

About 90% of the time that this code is set, the one-way check valves have worn out or failed and allow water (which occurs naturally in the exhaust) back into the pump. In any cold climate, especially in the northeast with higher humidity, this water may be more excessive. The water partially fills the AIR pump, it can then freeze. When the PCM commands the pump on, if the pump is frozen it cannot turn, thus overloading the circuit and "popping" the fuse.

As far as the location of the fuse, it is in the right front fender well beside the battery, and in front of the horn there.

Sometimes replacing the fuse will fix all your problems and you are all set until next winter when it all happens again.

Also, sometimes water is allowed to enter the pump through the intake side of the system (just a 5/8" hose behind the fan shroud) and ruins the system that way. -I'll talk about that in a moment.

GM says that when this system failure occurs due to water intrusion, the pump MUST be replaced. I have had decent luck just blowing the pump out with direct power provided by a test bettery out of the vehicle, and saving the customer some $$$ :thumbsup:

GM has also released a remote air intake kit that includes a longer 5/8" hose, a control solenoid, and a one-way check valve to eliminate most possibility of water intrusion.

Like I said before, sometimes just blowing out the motor and replacing the fuse will solve your problem. BUT, to truly repair the problem correctly the AIR pump, the fuse, and the exhaust check valves must be replaced, and the remote air intake kit must be installed. :banghead: $$$

I have much experience with this AIR system. Here in the northeast it is a BIG problem, and we have replaced at least 100 AIR pumps in the last 2 years or so.

If your vehicle is still under warranty, then you are lucky. --> The exhaust check valves usually wear out after 3-4 years thus, putting most vehicles out of warranty coverage. :sly:

Hope this explains the infamous (at least here in the northeast) P0410.

1.25 hours

usually running hot coincides with a lack of coolant. Low coolant levels will eliminate circulation of coolant through heater core. ALMOST END RESULT----NO HEAT

You will need some basic tools a 10mm socket ratchet with and extension , a 13mm socket. first remove the camshaft cover there should be 1 bolt on top and 2 nuts on the side of it all three are 10mm. now you have access to the water pump tension pulley then use your 13mm socket and put on the bolt which holds the pulley in place and turn it like you are gonna tighten it. and the hold tensioner is gonna move forward and take tension off the belt now you can remove the belt off the camshaft pulley and push it downward and off the water pump to install reverse the order.

Hit INFORMATION button until oil percentage is displayed. Press and hold reset until display reads 100%

A 97 Deville would be equipped with the Northstar V8 engine, therefore, it has 8 spark plugs.

27.5 USG the answer found here of 27.5 gallons is incorrect. the actual capacity is 18.2 gallons. the previous body style sedan and coupe may have had a larger tank but when they switched to front drive transverse engine it had an 18 gall tank.

Red and black wires are +12- volt, jumper the gray wire to ground to test.

This is very very complicated but, it is very possible to open this hood. You could get under the hood (if possible loosen the panel) and physically make the latch operate, if that is not possible you could take off the bumper, then take off, thenn take off the grill and use a flathead screwdriver to wedge it off. The second method takes more work but very possible, good luck with this.

Get a piece of thick welding rod appo. 30in. to bend and make a tool .1st, bend 90d @1 inch. 2sec. bend 45d@ 4inch. 3rd. bend @ end 90d appo. the last 3in of the rod. now you nedd to slip this in behind the latch and hook the release .this is between the hood and the radiator core support. you are fishing for the release you will pull it to the drivers side of the car. it really helps if you can find a cadillac deville 1985 fwd to 1993 fwd look at the latch and you will see how this tool will work.GOOD LUCK!

Most fuel filters for injected GM vehicles are on the drivers side, under the vehicle.

how would you remove the rear speakers to a cadillac sedan deville 1990.

use 7 1/2 quarts of oil, it will use a half a quart if you use 8 quarts. oil rings carbon up and stick, there is a decarbon process for this.

First off you will need lots of money. Going from an A/T to a manual requires many parts and much modifications unless you can find a donor car to remove parts from. As there was no 2002 Cadillac Deville built with a manual transmission, you will have to fabricate parts and modify others. This would be a daunting task.

spent 10 hours and got to a point where I could get the exhausts pipes off,go'n to look for someone to finish the job... ;(

got shift solenoid put in transmission and need it to read the need parts

most cars back then were 6x9.

Under the battery tray

A person can reset the air ride suspension on a Cadillac Deville by disconnecting the compressor wiring harness from the compressor itself. This is accomplished by putting the vehicle on ramps.

How do u fix PO304 on my 2003 cadillac deville my engine keeps shacking I change my spark plugs it help a Lil bit but I don't know to change the coil pack.sumbody told me that I must have air leak by the throttle.

It can be a vacuum leak or intake mini fold gasket leak. It can also be bad plug wires.

brake go down and lock pad
