Where is the blower control module located on a 1992 98 Oldsmobile?
Under the maxifuse center on the firewall - directly in the top of the blower / heater assembly. You will need to remove the two screws that hold the fuse / relay box in place to get to the module.
What happens if water gets in your car cylinder?
Depends on if the engine was running at the time. If the engine was running and ingested a lot of water, it would lead to fractured pistons and broken rods. Water, like most liquids, is not compressible, so as the piston moved up to compress the volume that is supposed to be gas and air, it would run into a brick wall. Something is going to break.
If the engine was not running and water seeped in, it might cause some rust in the cylinder if it wasn't gotten out fairly soon. Do not try turning the engine over, as some of the pistons will be in compression stage at any given time. See above.
If you're talking about a coolant leak, you'll see white smoke coming out of the exhaust pipe as it burns off.
High-performance engines sometimes actually inject small amounts of water into the cylinders since it will flash off as steam, carrying away some of the heat and giving a boost to the power stroke. Water expands something like 1500 times in volume when changed to steam.
You have an overheating problem it's not the radiator or the thermostat?
You say it's not the radiator, but when coolant in radiators is not flushed out at service intervals, corrosion can occur inside the radiator, diminishing coolant flow. This would present as overheating, especially in the summer months. Radiator flush/cleaing services are sold at Jiffy-Lube, etc, but you can get the same chemical packets at Pep Boys, NAPA, etc. Good Luck Also: check to see if you have water coming in your passenger side. Check the floor for wetness, and if it smells like antifreeze. This is your heater core gone bad Defective water pump, fan, fan clutch if equipped, fan thermal relay.
It uses a special blend of oil that is called supercharged oil from GM. Here is a link similar to the one you are looking for

On a 1994 Oldsmobile regency 98 where and which one is the ac blower motor relay?
Under the hood under the plastic maxifuse center on the firewall you will see several relays there. The blower relay is the 1st or 2nd on the left hand side. The other is the ac clutch relay - feel the one that clinks with the ac and the blower is the other one.
1992 Oldsmobile 98 regency elite 3800 chugs and sometimes backfires when under heavy acceleration?
Check fuel pressure regulator. Located behind the trottle on top of the plastic upper intake manifold. If fuel comes out when you take off vacuum line, replace fuel pressure regulator. Cheap fix. Good luck.
How does brain box of a car work?
Car Brain Boxes are electronic devices that incorporates microprocessors for the monitoring and control of various functions in a vehicle.
The brain boxes in most cases are specialized devices focusing on controlling multiple functions in a vehicle e.g. cruise control, automatic gear shifting, climate control, engine running, Fuel injection / emission control, collision avoidance, Powered mirror, seat & rear mirror controls etc.
These are usually custom built for different car manufacturing companies and are usually multi-purpose.
An electronic enthusiast can usually develop some simple brain box controllers for his/her car using PIC Microcontrollers for functions they desire to have in their vehicles but which did not come packaged with it.
I developed a small module for my car that automatically winds up the car windows, locks the doors after 30 minutes of shutting down the engine and closing all doors. The controller also doubles as a security system that taps into the cars injector firing system which cleverly avoids the normal areas car robbers would look into to disable car security system.
A brain box is usually much more complex than this, doing lots of complex calculations and taking complicated decisions to run the vehicle maximally.

Someone emailed this question: How do I go about building one?
You need the following:
1. A very good understanding of your vehicles' wiring system
2. Depending on what you want to do, you may also need to have very good understanding of the principles behind the function you want to control.
3. If your brainbox is already controlling the function, it's advisable not to do any parallel control of this function, one or both controllers will malfunction.
4. If your brainbox is already taking input from any sensor which you also need as input, ensure the way you pick this input would not affect the signal level to the brainbox.
5. If you're sending out an output, ensure it does not go into an input or output pin of your brain box.
6. Generally, I'd adviceyou steer clear of your car's existing brainbox to avoid damage to your car.
7. If you must add a functionality to your car, then go about it as follows:
a. First put your thoughts down as they come, note down every little thing that comes to mind.
b. Arrange these thoughts in a logical manner and then draw a flowchart or a state machine diagram of the function you want, to represent this thinking, starting from the inputs to the desired output.
c. Select the PIC microcontroller that fits your design in terms of - no of inputs & output pins required, size & types of memory, number of ADCs, Timers, etc.
d. Draw up your schematic and identify / calculate the sizes of all the components required.
e. Set up a prototyping board for your chip where you can both code and simulate. (use switches, variable resistors etc to simulate inputs and motors, LEDs, etc to simulate outputs).
f. Develop code (a little at a time), download and test run, debug errors, re-code and test-run again until ok. I discovered it's usually easier to break your project into several small sections which makes coding easy.
g. Move to the next stage of coding, until you've completed everything.
h. Depending on your experience, you may need to read a lot, pick up coding tricks frrom the internet or friends, learn how to use interrupts and subroutines etc to simplify your work.
I. Keep It Simple.
j. When you believe you have a working version, take it to your car and connect "live". Do not forget to regulate the car's 12v down to the microcontrollers voltage otherwise you burn the controller.
k. Do a test run in the live environment, notice assumptions made that failed and other corrections needed. Go back and re-work as appropriate.
l. Design and print a PCB. Transfer the whole circuit onto this.
m. Design a packaging material to enclose and protect your circuit.
n. Install and commission (Fine tune)
o. Enjoy the fruit of your labour!
Where is the fuel filter located on a 1992 Oldsmobile Ninety-Eight?

What is the firing order for a 1991 Oldsmobile ninety-eight?
For your 1991 Oldsmobile 98: Firing Order 1-6-5-4-3-2 Standing in frony of the vehicle the cylinders from left to right are 1-3-5 and the farthest one on the backside are from left to right 2-4-6 NOTE: There are 2 different motors used this year. The Canadian motor produced runs in reverse order. But this motor is very rare as they only istalled approx. 500 of these motors in the 1991 model. Most of them were used in following year.
How do you replace timing belt on 1987 Oldsmobile ninety eight?
It does not have a timing belt. It has a timing chain. The chain will normally last until the engine needs an overhaul. Not a normal maintenance item. It does not have a timing belt.

Where is the throttle position sensor located on a 1996 Oldsmobile 98?
On the bottom of the throttle body - look where the pedal cable meets with the throttle body - look opposite the end of the connection assembly on the other side you will see the throttle position sensor.
the compressor was working and now it has stopped, the clutch spins free but when i put my tester to the wires that connect to the compressor there is no power and the clutch dose not jump on can you help.
How do you set the timing on an 1989 Oldsmobile 98 Regency?
Hey Faith==You don't. It is electricaly controled. GoodluckJoe
how about the camshaft, valve timing, if the chain jumped on the sprocket wouldn't that cause timing to be off?
I believe 1985 Regencies had a distributor cap and was adjustable. 1986 and on are "fixed" and computer-controlled. Nothing you can do on it. If your car is "pinging" on acceleration or while going uphill, try the next higher octane gasoline. My 1990 Regency pings on regular gas, I have no problem on midgrade.
GMS
Another member brought up a good point: if the timing chain jumped a tooth on the sprocket, the timing would definitely be off. What are your symptoms/reasons for wanting to adjust the timing? GMS
Where is the fuel filter on a 1988 Oldsmobile Ninety Eight Regency Brougham?
it is located on the drivers side, approximately under the hinges of the rear passenger door.
Where is the oil filter for the 1992 Oldsmobile Ninety Eight located?
On the passenger side underneath the engine near the rear firewall.
Where is the fan relay on the firewall located on a Oldsmobile Ninety-Eight?
two places by battery or passenger fender look like little boxs on fender with pluges on them. There is a plastic covering in front of the passengers side firewall under it will be two relays ,switch them then check the operation of the blower and replace the one that is bad. Reminder: Always remove the ground cable from the battery before changing relays-sensors etc.
Where is the fuel pump on an Oldsmobile 1979 98 regency?
The fuel filter is under the front passengers side of the motor on the frame rail, fuel pump is inside the tank.
have to change core thruogh plenum on inside of car so if AC evap is in way will have to be removed, PSTTTT If dont have to and take someones advice will cost more then the 20 bucks for a repair manuel, go buy one it pays
How do you replace crankshaft position sensor on a 1988 olds 98?
To replace the crank
sensor you have to remove the harmonic balance taking special attention not to damage the pulley or the cam shaft. Remove the two 10mm retaining screws
What is the type of refrigerant used in a 1994 Oldsmobile 98?
It is R134a. Please under NO circumstances use the refrigerant that has stop leak added. If you have to take it to a repair shop and need repairs, it will ruin the equipment that is used to recover the refrigerant. Also, you need to be exact in the amount that is in the system. There should be a sticker under the hood with all of the information on it.
