The aircon controller is about to die - it has a bad connection inside it that is cutting power to the controlling vents. To find what exactly is the problem the controller must be tested by a pro - it's a long and fiddly job that will be quite expensive : in the worst case - the controller must be replaced - you could end up with a bill of over$500.

It would be difficult to find a complete manual online for free but you might want to try a salvge yard because they keep the manuals and sell them cheap.

The ride level system uses an air compressor and either an air type of shocks or a type of air billow to raise and lower the vehicle, there is an adjustment to set the ride height and it is located under the vehicle and there is a control lever or rod that should be connected between the rear axle and a switch that is mounted on the body of the vehicle, and there will be an adjustment slot in the control lever between the switch and the body, and that is how you would adjust the ride level height, but be sure that the vehicle can not drop any further down if someone is under the vehicle trying to adjust the ride height.

However, you might find that the control lever to the ride level has fallen off from the switch on the body or it has come loose from the rear axle, and it is just hanging there not operating the switch on the body that controls the the ride level compressor.

Thermostat is stuck closed it is usually located under the flange that your top radiator hose attaches too. but since you didn't include engine information I can't say that with 100% certainty. Usually you just follow the top hose from the radiator. It is attached to a flange that is attached to the motor with two bolts. Remove the hose, remove the two bolts and the flange comes off. The thermostat justs rests in a little depression there remove it and replace it very cheap part. Make sure you use the gasket that comes with the new one. Difficulty rating: easy. Also cheap to have done. There are a couple of Caddy engines though where it is under the alternator and compressor, and the alternator bolt also holds the tensioner for the serpentine belt. Difficulty level goes way up on that one!

A leak seems the most likely suspect, but a visual inspection doesn't detect one. Pull the relay and then check the control circuit (LED test
light)... if the LED does not light-up, replace the SAI relay. The other possible reasons for air pump not running are Blown air pump fuse,Blown/shorted Air pump motor, The air pump filter clogged or loose. The secondary air solenoid leaking vacuum causing air pump valve to open at incorrect time (possibly from water intrusion); replace solenoid. Check out.Thanks.

there is a plastic black cover on the front of the engine compartment that has a couple of creases in it where you can lift the cover to reveal the headlight bulbs from behind the lenses. Change the light bulb by rotating the black plastic ring counter clockwise to release the bulb from its socket. Also, pull the electrical connector off the bulb.

The motor is a difficult part to remove. I suggest a certified mechanic to replace this part for you. The blower control module is built into this motor and I have seen some cars come in by people who had tried to replace their own as you want to, although the motor was removed and the new one was destroyed by improper technique of installation
The money spent to replace one time is enough to spend and receive a guarantee as well

Could be your power antena, open trunk and listen for noise, if it is you could unplug elec. harness to it, radio will still work.

Using the Cadillac on-board diagnostic display you'll also see "IP" for the IPC instrument panel, "AC" for the air conditioning module, "TC" for traction control, "RS" for the road suspension system, "SD" for the air bags, "PZ" for the body control module, "CC" for the cell phone and "RF" for the integrated radio.



C1276 Delivered Torque Signal Circuit Malfunction

Check your Trasnmission for any wrong solenoids or Torque Converter.

the fuse box should be under the hood in the engine compartment or inside under steering column. check there i don't know why you are looking at the rear of the car.

Seville With 4.6L Engine
On some models, the generator is water-cooled. When this is the case, the repair procedure is as follows:

1. Disconnect the negative battery cable.
2. Remove the accessory drive belt.
3. Drain and recycle the engine coolant.
4. Remove the radiator.
   

NOTE If your vehicle is equipped with air conditioning, refer to the information regarding the implications of servicing your A/C system yourself. Only an MVAC-trained, EPA-certified, automotive technician should service the A/C system or its components.

1. Remove the A/C condenser.
2. Raise and safely support the vehicle securely.
3. Disconnect the coolant inlet and outlet hoses from the generator.
4. Detach the electrical connections from the generator. The regulator, the battery output, and the heated windshield (if equipped) will need to be unplugged.

Hope this helo to solve it (remember comment and rated this).

what makes u say ur ac refrigerant has a blocked passage? check the low pressure line by touching it with ur hand while ac is running/ it has to be freezing cold/ if not cooling it means ur compressor is weak and or refrigerant is low/ high pressure line is normally hot/ check ac magnetic clutch operation must engage when ac switch is on and disengage when ac is turned off/ check ac condenser must be blocked and needs cleaning....

Hi over heating could be down to a few problems, the first thing i would do is get the thermostat replaced as this is going to be the most likely cause of the problem.

But the problem could be much worse so you should take the thermostat out and have a good look at it then get a tub and fill it with boiling water then place the thermostat into the hot water and leave for about 30sec to a minute then take it out using pliers so you dont burn your fingers then have a look at the middle part and see if it has opened up to allow water to pass through it now if it dont open up then this is going to be the cause of your problem.

How ever if it does open up then it points to something more serious being the cause of the problem, so the next thing to look at would be the water pump and the head gasket, so if the thermostat is good i would then get the coolant tested for engine gasses this is often called a sniff test it involve placing a tool into the coolant filler bottle and it then test the gasses to see if your getting any gasses from the engine mixing in with the coolant if their are then it would point towards head gasket failure but if their is no problem then it would point towards the water pump failing so replacing this would be your next option.

How ever bare in mind that if the head gasket is proven to be the fault then this could have been caused by the over heating due to the water pump failing so if you have to get the head gasket replaced make sure that the water pump is looked at as it is a lot easier to replace whilst the cylinder head is removed.

So test the thermostat first if its not opening up then replace and try your car remember to fill the coolant slowly to prevent air locks and open any bleed screws that may be in one of the top hoses running around the engine not doing this would cause an air lock and it would over heat again so take car when filling the coolant up just trickle the water in to ensure you have no air lock.

Let me know how you get on or if you need further assistance ok

All of them. A/C,power steering,water pump,air pump,etc...

you need to check the fuses and the wires to the blower motor or you may just have a bad motor itself give these websites a try www.alldatadiy.com and www.autozone.com i also like to give you this information if you every have any hard to find GM-parts they only sells GM its Schram auto & truck parts 1-800-292-1032 and they websites is www.schramauto.com wish you the best of luck Michigan Man.

all general motors vehivles from 97-2005 contain an anti-theft system, called a passlock system. try this it will work on a malibu theft system. turn key on engine off for about 10 minutes,after 10 minutes turn key off. wait 15 seconds then try to start car. if it is the passlock system this will reset it.

the aan and mln is the modle it goes to. aan is for sls and the mln is for deville. as long as the conectors are the same thair should be no problems. i changed a 4t60e out of a 95 deville and the id tag was difrent then the replacement transmission id tag and a year later its still driving so . im gonna say ya it should be fine

On 4.6 engine the starter is located under the intake manifold. Since you remove the intake manifold you will see the starter.

Assuming no accident damage check the catch itself in the trunk lid, using a screw driver try to toggle the lasch, it should be rfee but has a strong spring to pop the lid up when opened, also try spraying some penetrating oil as likely it has become sticky with age and water.

Allow it to cool down and refill system while running with heater on hot. Hopefully this will get the air out of the system. However, if this condition persists, have the radiator checked for hydrocarbons. These engines are sensitive to overheat and you may have blown a head gasket. (hope not)
Good luck!
