Question about 1995 Cadillac Eldorado

2 Answers

Without a/c-heat engaged, the cooling fans do not operate untill temp reaches 223. They operate at a lower rpm than high rpm and do not stay operational to keep the temp between 198-203 which is what it used to operate at..Should I replace just the sensor...where is it located...these newer vehicles intimidate me...too many sensors, relays..etc., any help would be much appreciated...I have another problem would like to address at another time, if someone there is willing..Thanks in advance....

There are 2 fuses for the cooling fans both under the hood 50 amp in thr rh maxi fuse block the other one is in the engine compartment a 10 amp there are 3 relays that control the fans. the relays are either located in the left foward part of the engine compartment or on the bottom of the radiator to identify the relays i would have the fans running and disconnect to see the cooling fans are controlled by the pcm. the pcm gets temp input from the coolant sensor all three will be located together.

223 is not that high, my fans kick on at 218, and run just in stop and go traffic, they shut off when you get back to cruising. The temp gauge switch is located in a bunch of different places, I would look first at the bottom hose on the engine, then look on the radiator itself for the switch. If you can find it, you can but the new one preset qt different temps. the parts store will help you find it if It isn't where I thought. If I was you, I would be looking at the coolant. They have little testers but I think they are only for freezing, but they would tell you how much coolant to water you have. it should be 50/50. Or something like that. Check it out, hope this helps.

Does my 2002 Cadillac Seville SLS have a cooling fan switch, and, if so, where is it located?


Cooling fan switch ?????? Has a engine coolant temp. sensor , That inputs info to the PCM/ECM - engine computer ! The PCM / ECM interpits the voltage signal from software programmed into it as to what temp . of the coolant is . When the engine coolant temp. reaches
The PCM commands the low-speed fans ON under the following conditions:
• The engine coolant temperature exceeds approximately 106°C (223°F).
• The transmission fluid temperature exceeds 150°C (302°F).
• The A/C pressure reaches 199 psi (1372 kPa).
The cooling fans will switch from low to OFF when the coolant temperature drops below 102°C (216°F).
The PCM commands the high-speed fans ON under the following conditions:
• The engine coolant temperature reaches 112°C (234°F).
• The transmission fluid temperature is more than 151°C (304°F).
• The A/C pressure reaches 260 psi (1792 kPa).
• Certain DTCs are set.
The cooling fans will switch from high to low, except when DTCs are set, when the coolant temperature drops below 106°C (223°F).

The PCM turns on the cooling fans by energizing three different relay's .

Where is the cooling fan switch located on my 2005 malibu 3.5liter v6


Cooling fan switch ? The cooling fans (2) on that motor are controlled by three relays . A coolant temp. sensor gives temp info to the PCM - engine computer .
During high speed operation the PCM supplies the ground path for the cooling fan 1 relay through the low speed cooling fan relay control circuit. After a 3 second delay, the PCM supplies a ground path for the cooling fan 2 relay and the cooling fan S/P relay through the high speed cooling fan relay control circuit. This energizes the cooling fan 2 relay coil, closes the relay contacts, and provides a ground path for the left cooling fan. At the same time the cooling fan S/P relay coil is energized closing the relay contacts and provides battery positive voltage from the cool fan 2 fuse on the cooling fan motor supply voltage circuit to the right cooling fan. During high speed fan operation, both engine cooling fans have their own ground path. The result is a parallel circuit with both fans running at high speed.
The PCM commands Low Speed Fans on under the following conditions:
• Engine coolant temperature exceeds approximately 106°C (223°F).
• When A/C is requested and the ambient temperature is more than 50°C (122°F).
• A/C refrigerant pressure exceeds 1 310 kPa (190 psi).
• After the vehicle is shut off if the engine coolant temperature at key-off is more than 140°C (284°F) and system voltage is more than 12 volts. The fans will stay on for approximately 3 minutes.
The PCM commands High Speed Fans on under the following conditions:
• Engine coolant temperature reaches 110°C (230°F).
• A/C refrigerant pressure exceeds 1 655 kPa (240 psi).
• When certain DTCs set .

05 rendezvous, where is the fan sending unit located


Are you talking about the radiator cooling fans ? If so there is no fan sending unit as you call it ! The fans are controlled by the BCM/PCM !
The engine cooling fan system is controlled by the body control module (BCM) and the powertrain control module (PCM) or engine control module (ECM). The BCM performs the calculations as to how long, when and what speed the cooling fans should turn on. The BCM then sends a class 2 message to the PCM/ECM to engage the cooling fan relays. If there is a malfunction with the BCM, the PCM/ECM will control the engine cooling fans independently. The engine cooling system consists of 2 electrical cooling fans and 3 fan relays. The relays are arranged in a series/parallel configuration that allows the PCM/ECM to operate both fans together at low or high speeds. The cooling fans and fan relays receive battery positive voltage from the underhood accessory wiring junction block. The ground path is provided at G100.
The BCM and PCM/ECM command Low Speed Fans on under the following conditions:
?€¢
Engine coolant temperature exceeds approximately 106?°C (223?°F).


?€¢
A/C refrigerant pressure exceeds 1 310 kPa (190 psi).


?€¢
After the vehicle is shut off if the engine coolant temperature at key-off is greater than 140?°C (284?°F) and system voltage is more than 12 volts. The fans will stay on for approximately 3 minutes.

The BCM and PCM/ECM command High Speed Fans on under the following conditions:
?€¢
Engine coolant temperature reaches 110?°C (230?°F).


?€¢
A/C refrigerant pressure exceeds 1 655 kPa (240 psi).


?€¢
When certain DTCs set.

IF the fan is controlled electronically it may be difficult to get a sensor that operates at a lower temperature. If you have a viscous fan hub it is possible to increase the amount of silicone fluid in the hub to make it work more efficiently. If you have an auto transmission then consider an external oil cooler as this will take the transmission heat out of the radiator in effect giving you a bigger radiator. It is possible to get thermostats with various opening settings but you may have to shop around to find one

A/c compressor won't engage and the cooling fan not operating


The cooling fan does not come on until the engine temp reaches 229 degrees. it is controlled by a cooling fan relay. Cheeck for power at the fan motor and check the relay. The A/C. If yuor a/c system is low on freon the low pressure switch on the accumulator will not complete the circuit for the clutch. Check the charge, voltage present at the clutch or the low pressure switch. You can install a jumper in place of the switch to test.

The reason for replacing the thermostat is improper cooling - not heating. The purpose of the thermostat is to shut off the flow of coolant through the engine allowing the temperature to build. When it reaches the temperature it wants the thermostat opens and allows coolant to flow to maintain the proper temp. Dodge Caravans have a track record for maintaining a low temperature until the engine is at higher rpm. While it is inconvenient in cold weather it it not bad. However, you want to check that your radiator fan is shutting off when it is cold. A fan that is staying on when it shouldn't could cause the temp to stay cooler.

Make sure the cooling fans are working when the engine reaches above normal temp,if they are not ,turn the ac on,and see if the cooling fans come on,if so,replace the coolant temp sensor,if it has a clutch fan,then replace it,for it is not staying engaged ,and is not turning fast enough to cool the radiator.

usually two types of clutches available,one engages with heat,the other is rpm controlled. The thermal clutch will stay quiet until the engine temp gets too high. Centrifical clutches seem to make more fan noise.
