2000 Cadillac DeVille - Page 5 - Answered Questions & Fixed issues
Why is my 2000 cadillac deville overheating but
I bought a 2000 caddy Deville off the side of the road, had a 800.00 sign on it, pullover to see it, a man came out and said he had it to four shops and they can't figure it out. gave 700.00 for it and had to tow it home., flushed radiator, heater core, and engine out, changed thermostat, checked water pump. this Northstar engine would over heat when driving it. Turned out to be the plastic cover underneith, it hooks to the front bumper and goes to the metal frame to block the wind. when it is missing, the wind blows in and back drafts the radiator so the fans can't do their job and cool the motor. a five dollar cover from the junkyard and it was fixed, crazy hu. I hope this helps someone.
Mass air flow sensor where it is on motor
Usually It is inline between the inlet on the intake tube and the air filter or the throttle body/butterfly valve. Most engines will stop running if you break the seal between this sensor and the manifold.
Number 8 cyl
when facing engine with hood up it should be the front of motor last plug on the drivers side.
What is the fix for a code p0171 problem
Lean condition bank 1 refers to the computers interpretation of information delivered by the o2 sensor for bank 1. Possible causes are many. First look at the sensor readings. You should see a fluctuation of voltage readings. If the sensor is not fluctuating it should set another code with it. The readings should be .05 v to about .455 volts normally. If the readings are lean then look at the fuel trims. They will likely be nowhere near 0. When the engine is right, the trims may go positive 3 to negative 3. If your short term fuel trim is say +18 and the long term fuel trim is say +20 at idle then try runnung the engine at a steady 1600 rpm and wait a minute till the readings level out. If they approach 0 then look for a vacuum leak. Let the engine idle and use choke cleaner spray to find the leak. Spray suspect areas and watch for changes in fuel trims.
How do I remove the drivers seat in a 2000 Cadilac ?
I'm not positive about the DeVille, but I've removed seats from lots of other vehicles, and some of that may translate over here.
There should be four bolts (studs, really) going down through the floor from the seat mount frame. You should be able to find the four nuts under the vehicle's floor pan, after you jack up the driver's side and put jack stands under it (if it falls, it WILL crush you to death). Loosen those four nuts but don't remove them.
Now back inside, feel underneath the seat - find all the electrical connectors. Unplug them ALL. Doublecheck, triplecheck, make sure you get them ALL.
NOW you can remove the four nuts underneath the vehicle, tip the seat rearward to verify that you got ALL the electrical connectors, and remove it. It's HEAVY.

just the switch, just electical
or the mechanical.?
the switch locks the steering, and may do park lock out
