SOURCE: !993 Buick Le Sabre Heater motor does not work at any speed.

I had the same problem with mine and I replaced the blower motor, and still didn't work. The problem ended up being the blower motor control module. I have the auto temp control, so my replacement part was pretty expensive. Found a used one online fairly cheap. Hope this helps.

If you purchase a repair manual it will contain the wiring diagram. Your local auto parts store sells these books. They may have to order the one you need. Also any book store can order what you need.
Two publishers are Chiltons and Hayes.

Under hood on the wiring ,there is a blue and a tan color code, what do they go to?>


Can't help you on this directly, but you should be able to find the schematics for your car on a site called ebsco.com. You need to be a paid member to access the site. However, most libraries have accounts. Go to your local branch and look it up using their system. Using it from there will be free. If you have a library card you can sometimes get online access from your home computer by using your card number and the u/n the library provides. Call them and ask, it may save you a trip.

How to replace a Jeep Cherokee Charge


Replacing a thermostat on most any car can be done with little auto repair experience. The thermostat is always in a visible and reachable spot. The Jeep Cherokee is even easier because the thermostat rests at the very top of the motor. The thermostat is a small piece that helps regulate the temperature of a vehicle.

Things You'll Need
Thermostat with gasket and gasket sealant
Accessories
Pliers
Flathead screwdriver
Mechanic's glove
Step 1
Park the vehicle in the shade on a flat surface. Turn the Jeep off and raise the hood. Let it sit and cool off for at least one hour.
Step 2
Slowly remove the radiator cap by twisting it with a thick towel. This will absorb any excess heat and pressure fluids. Be sure to wear your gloves. When removing the cap, extend your arm, creating maximum distance between you and the Jeep and turn your face away for safety precautions.
Step 3
Place an empty 2-gallon bucket under the very front end of the Jeep. Lay down under the front end of the Jeep and locate the bottom of the radiator. Look for a small, twist-off plug near the end of the radiator. It should read "Drain Plug." Place the bucket directly under the plug, and slowly remove it. Allow the antifreeze to drain completely.
Step 4
Place a water hose in the top of the radiator and turn it on. Turn on the car and allow the water to run through the radiator and cooling system for five to 10 minutes. This is called flushing the radiator, something you always should do before replacing the thermostat.
Step 5
Turn off the vehicle. Don't reattach the radiator cap or the drain plug.
Step 6
Locate the wide black hose directly under, or connected to, the radiator cap. Follow the hose to the end, which will be the motor. Using your pliers, squeeze the ends of the hose clamps together and pull it back. This will release the grip pressure.
Step 7
Wiggle off the hose. Let the excess fluid drain. The thermostat will be exposed. Unscrew the two nuts securing the thermostat to the motor. Using a flathead screwdriver, drive a wedge between the thermostat and the motor, popping it out.
Step 8
Peel off the blue or black gasket that was sealed to the motor. It should come off easily.
Step 9
Place the new gasket on with the provided sealant. Screw the new thermostat on, precisely in the location and pattern that you removed the old one. Wiggle the black hose back on and secure it with the hose clamp.
Step 10
Put the drain plug back in snugly. Fill up the radiator with a gallon of a solution that is half antifreeze, half water. Turn the Jeep on to circulate the antifreeze. Check for leaks near the thermostat and the drain plug. While the Jeep is running, add another gallon of the antifreeze/water solution. This should completely top it off. Place the radiator cap on, and you're done.

Stalled 06 Ford Explorer in Water, now it won't start.


How deep was the water? If it was above mid way on the motor, you probably got water in the cylinders. You also may have gotten water under the distributor cap. remove a spark plug and have a helper turn over the motor as you watch for spitting from the spark plug hole. Check the spark plugs closest to the back of the truck. I hope there was no water in the cylinders - if there is spitting, you may have bent a valve - or worse! If no spitting, get some wire dryer spray from your local auto parts store, remove the distributor cap, and liberally spray the inside of the cap and the rotor, as well as they distributor plate and assembly. Give it 30 mins or so to dry out and replace cap, then try starting. If no starting, remove a spark plug and wire. Put the wire on the plug and hold with some INSULATED pliers, holding the electrode end of the plug on the engine. Have a helper start the motor and watch for a BLUE spark from the plug. If the spark is yellow or orange, you don't have enough power to run the motor and may have a faulty coil or coilpack.
Hope this helps and thanks for using Fixya!!

Where is the computer located


The Computer is under the dash board behind the glove box, (First) before you do anything.... Disconect the (NEG) battery cable!!!! Then inside the car, You must remove the lower dash plastic shield held on by 10 screws and then 5 screws holding the base of the glove box. Let the glove box drop down out of the way. Look at the upper back foot wall for a SILVER METAL BOX with (3) big wire plugs. The plugs are (RED - WHITE & BLUE) that's the computer unit. It's mounted on a thick hard plastic back board. Use a Blade screw driver to push on the corners of the back board as you push up to release the snaps of the computer. Do this to both corner snaps. Once you have done that You can pull the computer down and out to the car floor.
Now use masking tape, mark each plug wires to match RED/WHITE/BLUE PLUGS!
Now squiz the ends of the plugs and pull hard to remove them. NOW your old computer is OUT... Buy a New / Rebuilt or USED compoter.
IT'S BEST that you Match the (DELCO NUMBER on your old one!)
**** DO NOT BUY ONE AT THE DEALER!!! THEY WILL KILL YOU BANK ACCOUNT!!!! BUY ONE AT JUNK YARD FOR UNDER $125... MAKE SURE IT IS A DELCO UNIT WITH THE SAME PART NUMBER AS YOUR OLD ONE! *** DO-NOT GIVE THE OLD UNIT TO THE JUNK YARD!!! ***

ONCE You have the repacement unit, remove two screws from the top shield of the new one and your old one. Inside you will see a (BLUE) plug in chip. You need to SWAP them from your old one to the new one.
Squiz and lift out and move your old one to the new computer.

DO-NOT Put it back in the dash yet.... After you have swaped the BLUE chip put the 2 screws back and plug in the RED, WHITE & BLUE big plugs back on the new computer. Let it lay on the car floor for now. Now, go under the hood and RECONECT the NEG to the battery.

Start your car and let it run checking for problems fixed!!! If all OK, take it for a short test drive... If all is well go home and put computer back and reasemble in reverce order. GOOD LUCK!!!

The heater fan just stopped...


Check fuse #14(10amp) located in fuse box under driver steering wheel behind the lower dash cover.
Check fuse#12(40amp) located in fuse box under hood.
Replace fuse(s) if any are blow.

If fuse are good.Check blower and transisto next.
Do steps 1-3 with turn key on
1. Unplug connector and check for 12v at the blue/white wire at the blower motor(2-NAT)
-if there's no voltage you might have a bad relay or open in the wire
-if there's about 12v, go to step 2
2.Plug connector for blower motor and unplug connector for blower transistor(4-NAT). Take a jumper wire and jump the blue/black wire to body ground.
-if blower does not run, replace blower motor
-if blower motor runs, go to step 3
3.check the black wire at(4-NAT) for good ground.
-if you have good ground, then replace blower motor transistor.
good luck

Where is the blower motor relay located on a 1997 buick lesabre.


There are 2 relays for the blower. The low blower relay and the high blower relay. They are both located
under the hood in the center of the firewall.
The low will have 4 wires from it, one lt. blue and 3 brown. The high will have 5 wires 1 purple(to blower mtr.) 1 black 1 dk blue 1 red and 1 orange.
Also, the blower resistor is in the same area if needed. Hope this helps.

2000 chevy blazer starts sometimes and sometimes not. replaced starter, spark plugs and wires and fuel pump. still same problem. could it be the mass air flow meter? Jackie


Check for spark by removing one of the plug wires from a spark plug and installing one of your old plugs in the removed wire (leave the other end of the wire attached to the cap). Rest the exposed plug on an under-hood surface that will provide a sufficient ground and have some one turn over the engine. You should se a strong blue spark. We have seen some intermittent coil problems on your generation Blazer that would explain a lack of spark. Good luck!

What causes serging when applying gas going up a hill


Your spark plug wires could be arcing. To check, find a dark place and raise the hood. Mist the plug wires with windex. Start the car and look for blue arcs coming off the wires. If you see them, replace the wires.

Chevy K1500 - Coil and plug spark loss


This is more common when there is a high level of moisture in the air especially with older components. Moisture can settle on the distributor and wires and act as a conductor. Since you are still having this problem with the new parts I would suggest using a moisture dissipating spray such as WD-40 or PB Blaster.
