There is nothing to worry about. The cooling fans do not operate by engine speed, but rather engine temp. If the fans stopped working, then there would be a problem with either the cooling fan relays or the temp sensor which operates the fans. Otherwise, you are fine.

Where is the speed sensor located on a 2003 buick rendezvous


Why ? speedometer not working ? Does the vehicle shift correctly ? The VSS - vehicle speed sensor is an input to the PCM - engine computer > Speed info is sent from the PCM to the microprocessor in the instrument cluster over the class 2 serial data bus . 2003 - 2006 GM vehicles had bad step motors in the instrument cluster . Step motors control gauge position. The VSS is located on the transmission case Vehicle Speed Sensor (VSS)
Lower right rear of the engine compartment, mounted to the right side of the transaxle.

Speedometer
The instrument panel cluster (IPC) displays the vehicle speed as determined by the powertrain control module (PCM). The PCM converts the data from the vehicle speed sensor to a 4000 pulses/mile signal. The IPC uses the vehicle speed signal circuit (4000 pulses/mile), class 2 message from the PCM in order to calculate the vehicle speed. If the IPC detects a malfunction in the vehicle speed signal circuit from the PCM, the IPC uses the class 2 message from the EBCM, indicating the vehicle speed as a backup. If the speedometer reaches (108 mph) the fuel with shut-off, and it will turn back ON when the speedometer is at (106 mph). The speedometer displays either miles or kilometers as requested by the activation of the English/metric button on the driver information center (DIC). The associated indicator (km/h or mph) illuminates.

2003 buick lesabre ac fan runs when car is cut off


How long does it run? The reason I ask is because it is designed to run after engine shut down under certain conditions of temperature to cool down the engine and prevent vapor lock in the fuel rail. If it just stays running all the time after the key is turned off that is of course a problem.

Cooling fans on 94 buick lesabre are coming on at about 100 degrees engine temp when A/C is not running.


Yes, it could. But there might be another little module or device at play here, tricking the relay for the fan to come on (wrong temp). Certainly the ECT sensor, if you experience other driveability symptoms or issues especially in that time between the fans coming on and the engine reaching normal operating temperature.
Well, maybe this is a little help on your way to solve it. A wiring diagram of the circuit is another option besides the engine CTS.. Good luck.

1998 buick lesabre the blower motor keeps running after car is turned off


if you are talking about the engine electric cooling fan..it will run after car is turned off until temp goes down then it shut off..unless you're talking about the heater blower motor..then i would look in the engine compartment passenger side firewall for the heater box ..on the box there is speed control resistor for the heater fan speed..that might be shorted.if not fan switch on dash..give more info next time..it makes it easier answer with more info

My chevy venture 2003 only over heats when it is still with the engine on but it does not over heat when i drive it, what could it be?


Odds are your electric cooling fan[s] isn't coming on. This fan should only run when the a/c is on or when the engine temperature has reached about 218 degrees. Once the a/c is off or the engine temp drops to about 210 degrees it shuts back off again. It rarely comes on at speeds over about 35 mph because at that speed enough air is forced through the radiator to keep the engine at about 198 degrees. I would start by looking for a blown 30 amp fuse under the hood. There may be two of them marked "Cooling fan 1" and "Cooling fan 2" or something similar. If the fuses are good you could have a faulty cooling fan motor that just isn't running. Hope this helps a bit!

Our car fan (Buick Lasabre-97) will not shut off. How can we shut it off? Will the battery eventually run down if we don't get it shut off?


yes the battery will drain down very fast. raise the hood and go to the under hood relay box look for cooling fan relay and remove there may be two one for low speed and one for high speed.or u can unplug the cooling fan it self.just a two wire connector may have to use a small flat screw driver to raise the retainer.hope this helps.
