You want to Operate the Air Conditioning Compressor ? IT is controlled by a pressure switch and is controlled automatically.Are you talking about Air Ride Suspension? The Air Compressor is also Pressure Controlled for this system

These early 90's vehicles had alot of problems with the antitheft systems. When they fail, they actually cut power to the starter or injectors. Look for a light on the dash that says SECURITY or ANTITHEFT. You see this light, go to this link for answers.http://vatspasslockpasskeysecurityhelp.yolasite.com/

the electic fan or its relay is bad

Hi. i have some unfortunate news to relay. There is a very strict rule that many Cadillac owners must obey. You should never let this model run hot under any circumstances. There are three possible issues here. Due to the fact that this engine is aluminum, the heat could have blown the head gaskets or, warped the heads as well. The next issue could be the freeze plug. i would check this and replace if needed. I would make sure the oil is not milky. this can confirm the blown head gasket. The final check i would recommend would be that you make sure the mechanic installed the thermostat correctly. the spring part of this device should be inserted in the motor not the other way around. sometimes, techs get in a rush and they install the thermostat in backwards. check the areas above and you should find the problem there.

Sounds like a stuck relay, turning the keys off kills the power going to the relay unsticking it.under your hood locate the fuse panel (or box what ever you'll like to call it). Under the cover of the fuse panel is a diagram showing you where all the relays and fuses are located. Locate the power window relay. buy a new one and replace it.

Find the fuse box either under the hood or under the dashboard and pull off the cover. The fuse locations are either on the fuse plug in area or on the cover you just removed!

The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems ca cause many drive-ability related problem such as rough idle and other symptoms

Duplicate question.

Raise the front end off the ground with a floor jack, fill the coolant recovery tank as high as possible and then run engine until it gets up to high normal temperature on gauge, shut the engine down and run water over the radiator core, the coolant will be pulled into the engine as the core is cooled, do not let the tank run dray during this process.

I suppose the belt could be slipping when it is warmed up.Have you checked the output of the alternator to make sure there are no weak connections between the alternator and the battery ?

You can run a system test using the data screen to check for trouble codes.Have you done that yet ?

Duplicate question.

sounds like you have bad plug wires, how did you test them, possible plug wires on wrong plug, need to check your firing order, check ignition coils also, also possible burnt valve if backfiring but bad wires or coils will cause also

Have the coolant checked;if ok i would have the thermostat checked and replaced.

check to see if compressor for air ride has power to it

Hi there:Check this procedure on 4.6L Engine (except Seville)...

1. Disconnect the negative battery cable.
2. Remove the cover from the headlamps and radiator shroud.
3. Remove the air cleaner, if necessary.
4. Disconnect the left engine torque strut from the radiator support.
5. Disconnect the upper trans oil cooler line from the trans cooler.
6. Remove the right cooling fan and the left cooling fan.
7. Remove the serpentine belt from the generator pulley.
8. Remove the bolt from the front top of the generator, and the bolt from the lower front of the generator.
9. Detach the harness connector and output cable from the generator.

NOTEThe bolt nearest the exhaust manifold cannot be removed from the bracket but can be backed out to allow for removal of the generator.

1. Removal the A/C splash shield from the cradle, and the access panel from the bottom side of the radiator support.
2. Disconnect the engine harness from the cradle.

NOTEThe generator can be moved out away from the engine and removed from the bottom side of the engine compartment.

1. Connect the negative battery cable.

To install:

1. Install the generator to mounting with the two bolts to the rear of the generator. Hand tighten the bolts.
2. Connect the engine harness clip to the cradle.
3. Install the access panel to the lower radiator support. Install the A/C splash shield to the cradle.
4. Attach the harness connector and output cable to the generator.
5. Tighten the rear mounting bolts to 36 ft. lbs. (47 Nm). The output cable to 15 ft. lbs. (20 Nm).
6. Install the bolt to the lower front of the generator and tighten to 36 ft. lbs. (47 Nm). Install the bolt to the top front of the generator and tighten to 36 ft. lbs. (47 Nm).
7. Rotate the drive belt tensioner and install the drive belt around the generator pulley. Inspect for correct alignment of the belt with all the accessory pulleys.
8. Install the left cooling fan, and then the right.
9. Attach the upper trans oil cooler line to the trans cooler.
10. Install the left engine torque strut.
11. If the air cleaner was removed, install it now.
12. Replace the cover from the headlamps and radiator shroud.
13. Connect the negative battery cable.
