1993 Cadillac DeVille - Page 5 - Answered Questions & Fixed issues

You may have more than one problem.The code F32 is for a problem between the engine computer and the body computer, or a loss of memory. To fix that someone would need to check the ground connections and the harness between the two computers.The engine could be burning coolant like the head gasket problem you mentioned.

With grate difficulty thats how, No diagram avaible,

Faulty coolant temperature sensor.

Duplicate question.

eather a broken vacuum like or the idle air controler is gummed up it is an eletronic soilinoid contriled by the engine computer and is located at the throddle body held in by two very small and hard to get out screws and electric connector it has be my experance the it will be the IAC valve as the new fuel mixes are gumming them up and they have to be replace cleaning them just wont do it Johnie G 35 yrs ASE Master

sounds like a loose connection on the starter or windings in the starter are going out suggest replacing the starter is your best bet it is taking all the amps from your battery and the other cars too

it will be under the dash it is a odd looking ADL rectanglar plug. did you know that you can use the dash panned to retrive the codes ?? dont need to hook up a external reader. refer to Code retrivial procedures 1993 Cadillac Deville in the problem area

This answer is ever so wrong and will get your car damaged or you hurt.

these procedure are for 95 thru 2000 devilles with a 4.6 l engines

1 jack vehicle and place on sutable jack stands, block rear tires

2 remove the lower air shourd from the engine crade under the front of the car , remove upper front cover over rad. and headlight adjustments

3. remove cap from coolant bottle, DISCONNECT NEGITIVE BATTERY CABLE Only

4 place a large catch basin under the left (driver side) of the vehicle

5 remove lower rad. at the thermostat housing CAUTION coolant will be flowing quite rapidly insure engine and coolant is cold before you start

6 remove upper rad. hose from the rad on the right side

7 carefully remove both electrical fans 10 MM retaing bolts, disconnect electrical connections and retaining zip ties , mark fan for proper reinstall as they are not interchangable

8 remove fan retaining mount from top of rad. long black plate

9 remove both 10 mm bolts retaining rad and supports

10 remove coolant catch basin and replace with a pan to catch transmission fluid

11 disconnect BOTH transmission cooler lines fron the left (drivers side) of the read one will be at the top and the other close to the bottom. some slight fluid will be lost ( approx 6 to 8 oz)

12 slightly tilt rad back at the top and remove from the vehicle. place upright in a secure position to prevent damage to the fins they can be damaged very easily.and costly to repair or replace

13 remove the right front tire from the vehicle

14 remove the right front inner fender splash sheild which is held in place with #2 crosstip screws and 7mm sheet metal screws

15 remove serpitine belt using 1/2 drive rachet or braker bar. ( I sugggest investing in a serpitine tensinor removal tool less than 30.00 and can be used on all kinds of other vehicles)

16 remove the 15mm bolt from lower Alt support it is between the battary ground connection and the A/C

compressor mounting bolt

17 using a 15 mm boxed end wrench remove the 15mm lower bolts behind the Alt you will have to get under the vehicle and they are tricky to remove as the exhaust and a bracket is very close and a scoket will not access them.

18 from the top of the engine disconnect the 10mm nut under the black plastic protective cap. be very careful as this is the positive lead back to the battery and will arc out and damage your battery if you did not disconnect the negative cable from the battery STEP 3

19 Carefully disconnect voltage regulator connection from alt.

20 remove final 15mm bolt from top rear of the alt. using a 15mm open ended wrench the bolt will not come all the way out and will hit the exhaust manifold.

remove alt from the vehicle.

21 start reversing procedures to install. REMEMBER to check your serpitine belt for cracks and dammage before you instll it I recommend to always replae it at this time to save future touble,

22 when installing serpitine belt have an assistant hold the tensioner up while you install the lower part of the belt install the belt on the tensioner pulley last.

23 after all bolts and covers have been installed replace lost coolant with DEXCOL 50/50 mix with water DONOT use the ethergylcol coolant as it will pnot mix and will damage the entire cooling system.

24 warm engine up to operating temp and replace coolant cap

25 check transmission fluid level with engine running and warm and in park top off as needed

26 check lug bolt torques

The Neutral Safety switch monitors the position of your gear selector lever and either interrupts or allows the starting circuit in your car or truck to do its job. On newer vehicles it may also monitor the position of the brake pedal to make sure that the vehicle is in park or neutral AND that your foot is on the brake. If your vehicle is equipped with a neutral safety switch, it should NOT start UNLESS the transmission is in Neutral or Park. On the other hand your vehicle SHOULD start when it is in Neutral or Park. If your car will start in Neutral but not in Park, you have a bad switch. Also, if your car or truck will only start by turning the key to the start position and wiggling the gear selector lever, your neutral safty switch is in need of replacement.The nuetral safety switch is usually found near the gear shifter. If your car has the gear shift on the column, then the neutral safety switch is usully mounted on the steering column near the brake pedal. On floor mount or console mount vehicles you will find the nuetral safety switch mounted near or on the shifter mechanism.

With great difficulty is the answer. First get yourself into the front floor space upside down, look with lamp at heater /water pipes leading to heater. if no leaks seen, take to repair shop.

I only show two red wires and a purple going to the starter.

Well it is usually behind the glove box - you would need to switch the prom from the old to the replacement.

Did you use the correct key code? That is not a chip it is a resistor embedded in the key shank. You must measure the resistance of the old key and then buy the correct key code to replace it or the system will lock the engine out. Please go here to help you understand how to obtain the correct key code

yes or hit with hammer on bottom

have you checked if you have oil?

check your battery,or not clean battery terminals,or starter motor solenoid.

A slow flash indicates that one of the signal bulbs has burned out. You need to check the turn signal bulbs as well as the marker lamp bulbs. The marker lamps on the the side of the vehicle.

could be heat sensor that controls fan turning on when motor reaches heat range. When defrost is on fan will come on automaticly over riding the sensor...Replace sensor is what i would suggest. Local autozone can help you out to the location and how to replace...hope this helps and if so please leave rating on this post and good luck.

the computer also called the body control module is located behind the glove box, there is 6 short phillips head screws holding it in place ,remove the screws and the glove box will pull out ,set it to the left side ,supporting it on the hump on the floor,you'll see two aluminun metal boxes held in place by a 10 m.m nut the larger of the two is the one ,it has two plugins on the end of it . that one is the computer.the other only has one plug on it ,it controls the air bags . remove the blue lock in pins un-clips,clips and firmly unplug the two plugs ,
