1994 buick skylark overheating why


Check the coolant level.
The radiator must be full, coolant should be mix of 50/50.
If it is full, and stays full when overheating, the most common cause is a defective cooling fan.
One of your electric radiator fans is for your A/C and one is for the radiator cooling
Any time the temperature gauge/ or red light comes on, that fan should be running.
Raise the hood and look the next time it overheats, and if no fans are running, you need get it fixed quick, lest you blow a head gasket.
The problem could be either the electric fan motor, or the sensor switch that screws into the engine block.
If the coolant stays full, and the fans are running, you may have a stuck or closed thermostat.
God bless your efforts.

Causes overheating


I HAD the same problem, fixed it. From my experience this is what you're going to do:

1. At cold start, see if the condenser fan or the radiator fan turns on right away. If yes, replace the Fan Control Module ($100 original). A/C and motor fan should only come on when temp is "normal", meaning the needle in the temperature gauge sits in the middle.

2. If the radiator fan does not come on when temp level needle reaches the middle of the gauge, your motor is dead and that's why you overheat pretty quickly. Replace radiator motor ($70 replacement). Or you can check if the motor is working by directly powering it from the battery. Use small cable jumper ($2 at Walmart)

3. Replace thermostat ($14 with thermostat gasket)
4. Drain existing coolant and put in new one.

Most of the time its the radiator fan that goes out pretty quickly due to faulty fan control module (that little black box that attaches to the fan assembly hood on the driver's side near the battery). I did all the repairs and saved a ton of labor cost. Its easy, just search it on youtube and they will show you how to do it. The solution I gave is what fixes mine.

Good Luck!

please follow this steps and fix it.
A fan failure, or a failure of the fan relay or control circuit is bad news because it can allow the engine to overheat.
Five things may prevent an electric cooling fan from coming on:
  • Defective temperature switch or coolant sensor
  • Engine thermostat is stuck OPEN (engine never gets hot enough to turn on the fan)
  • Failed fan relay
  • A wiring problem (blown fuse, loose or corroded connector, shorts, opens, etc.)
  • Bad fan motor
ELECTRIC COOLING FAN QUICK CHECKS.
One way to quick check the fan circuit is to start the engine and turn on the A/C to max. If the fan runs, the fan motor, relay, fuse and wiring are all okay. But this test doesn't show if the temperature switch or temperature sensor and PCM are energizing the fan when coolant temperatures are high.
To check the temperature at which the fan comes on, turn the A/C off and keep the engine running until it reaches normal operating temperature. Most fans should come on when the coolant reaches about 200 to 230 degrees. If the fan does not come on, something in the control circuit is defective. Resistance checks should then be made on the temperature sensor or switch, and a voltage check on both sides of the relay (you will probably need a wiring diagram of the fan cooling circuit on your vehicle to identify the relay terminals and wiring connections).
The fan motor itself can be checked by using jumper wires. Unplug the wiring connector on the fan, and use the jumper wires from the battery to route power directly to the fan. If the fan motor is good, the fan should spin at normal speed when supplied with 12 volts. Noisy bearings or a slower than normal speed would indicate a worn motor.

How do I fix the blower fan in my Ford F-150? It's STUCK on HIGH!


the problem is not the fan (blower motor) , it is the resistor in the blower motor hosing under the hood...
open the hood and look over by the passangers side firewall to locate the blower plenum (housing).
There is a plug that has 4 wires and it is plugged dirrectly to the housing.behind that is the resistor configuration that runs the fan at the different speeds ( more resistance = slower fan speed).
It is this part you need to replace.

The fan is stuck blowing on high, the knob turns etc... but the fan and condenser run full blast


Check the connection at the heater blower motor resistor.Wiggle or pull connector off and look for a melted pigtail these get very hot and usally are the cause of fan motor problems.Its located on passenger side of heat duct mounted with 2 screws.

Did you check the coolant level? if your low on coolant the sensor for the fans won't work, also could be a bad fan motor or just a fuse, if you continue to over heat the car you can do a lot of damage to the engine, blown head gasket, and the VW's are expensive to repair, take it to a good shop and have them check it out.

Quick temp. rise, with an inconsistant knock. water pump suspected!?


The water pump may have a bearing type noise if bad or a slow leak. The quick temp rise may be air in the coolant. I assume you have plenty of coolant in the motor right now. Also, make sure there is no coolant in the oil. It would be a milky, white, or gray color. And of course, the thermostat may be sticking, this is usually a quick fix and inexpensive. At least that will eliminate one cause. take care and good luck. Oh yeah, is your cooling fan kicking on, or does the temp rise even before your motor gets warm to the touch? If the fan is not kicking on when it needs to, then it could be the wiring to the thermostatic switch or the switch itself. Or of course, the fan itself.

Fan relay switch stuck open


if the relay was stuck "open" then your fan would not run... is this what you meant?

additionally, are you talking about the exterior fan for the A/C and radiator or the interior fan for the blower motor?
