Question about 1993 Buick Park Avenue

1 Answer

Cooling fans do not work

The car over heats because the fans do not turn on. Could it be a fuse or relay?
Also the car starts off sluggish but runs good after you get going.

Unplug the fan on sensor. It should have one green wire and one black wire. Use a paper clip and jump the two wires. Turn the key to the run position, the engine does not need to be running. Does the fan come on? If not check the green wire for 12 volts and the black wire for ground. If there is no ground than run a new ground wire. If the is no power check the heater/air conditioning fuse in the under dash fuse block. If there is power and ground make sure both the cooling fan fuses are good and both the cooling fan relays are good.

Why does my fan keep running in my 2003 Volvo S 60 after the car is off?


It can be faulty fan relay.The relay is not turning the system off.Or its wire short issue.Even with ignition off ,the fan relay is getting power so its not letting the fan to turn off.Bypass the fan control relay and see if still the fan works with ignition off or not.

2002 impala 3.8. Overheated. Had coolant leak.Replaced bad coolant elbows and thermostat with fail-safe. Car still overheats. Noticed cooling fans not running when A/C turned on. Blown fuses. Replaced....


A bad relay will not blow a fuse. The radiator cooling fan must run with the A/C on or the vehicle will overheat and the A/C will perform poorly. First I would check the draw on you cooling fan motor-it may be blowing the fuse, or you have a wire shorted to ground.

I have a 2004 chevy cavalier, 1st problem when stopped at a red light with a/c on the temp. goes up and a/c starts to blow warm air and car runs sluggish. Like it wants to stall. When driving everything...


first problem is simply your radiator cooling fans (there tow of them) are not working my be due to a fuse and/or relay those fans are turning with ac on even if your car is cold and turns when radiator gots hot even if ac is off
so when your car is hot open the hood and just take a look are they running or not they just in front of radiator

Cooling fans won't run


Check the cooling fan relays,and the fuses,also if the thermostat is stuck,the coolant sensor will not sense the hot coolant,and will not activate the relay that turns the cooling fans on,also,if the coolant is low,or has air in the system it will do this also.

2003 malibu cooling fans don't work. I have replace the relay and the temp sensor and still nothing. When ever I disconnect the temp sensor the fans come on and work normally, but later in the day I see...


okay pull the temp sensor connector ( disconnect it) and turn car on if the fans run then its the temp sensor.... part # wt3000.
Theres also 3 relays that turn the fans on in the fuse box cooling mode fan relay @15 which is part number 7234. and cooling one # 1 which is 3604, and cooling fan #2 which is 7236.
I have the same car...give me a fan clutch cooling system anyway of the week. simple and efective no problems.

Car overheating; cooling fan not working


This is most likely caused by a bad sensor in the radiator. I have never repaired this on a ford focus so I can't tell you where the sensor is located but if you find the sensor and then make a jumper wire and remove the wire from the sensor and jump the two wires together and turn the car ON (don't start the car) if the fan runs, the sensor is bad and must be replaced.
