Question about 1997 Toyota Camry

Open Question

Toyota camry csx heater/cooling fan very slow

CSX has an electronic fan speed controller. pushing the increase/decrese speed buttons has no effect on the speed of the fan, even though the bars on the LCD screen indicate that the speed is higher or lower. Can someone indicate the possible cause and eventual a replacement part source. Thanks a lot.

SOURCE: replace glass screen on the 60 csx garmin

yeah sure with some handy work and a llittle patience you shouldnt have a problem just remove all the screws, be careful not to tear any wires remove the internal componets from your face plate take a small prying tool and remove the glass , just a few dabs of superglue and your back in business! if you want a shatter proof you can alsi use plexi glass.... and if your really adventerous you could remove the standard led's and put custom colors in .... but beware soldering on a board can be dangerous

SOURCE: toyota avalon csx 2000 cd player

I had the same problem. It is probably the laser reader for the CD player. I took it in to the dealer and was referred to a vender as the warranty had expired. I took it the vender 10 days ago and just had it re-installed today. Works well. BTW, the dealer took it out and send it to another company which repaired it and sent it back.

The control panel is held in by 4 clips, one at each corner. You need a long, flat tool, preferably hard nylon, insert it at the bottom corners & pry backwards, ther clips will release, and you then pull the top towards you to release the 2 top clips. The bulbs are on the back of the control assembly. Don't use a screwdriver, it will damage the material around the panel.

SOURCE: heater

the 1st thing is to see if the heater core has flow, check this by touching the in and out hose of the core at the engine firewall, if both are hot then the heater core is ok, at that point u will have to check the blend door to see if it moves, this door diverts the air over the hot heater core or the cold AC evaporator core, it is often controlled by a small special electric motor, it is called the blend door actuator motor, if it fails it will useually fail in the cold air position, to change this motor u must remove the dash.

SOURCE: steering hand controls for Philips DC479 rds

If you have a aftermarket cd player installed you have to get something called a wireless controller. Basicly it hooks up to you steering wheel controls and you program your remote to you wireless controller and it sends a signle just like your remote when you use the steering wheel controls. Hope this helps, good ratings help me out. Have a good day.

The cooling fan is supposed to come on when the /ac compressor clutch cycles on, and off when it cycles off.
The idle speed kicks up to compensate for the additional a/c compressor load and the additional alternator load. usually, just the low speed comes on until it hits a much higher temperature.

the system should cycle 4 to 7 times/minute at 79 degrees F.

Here are some things to consider:(The PCM (engine computer) is NEVER defective, don't replace it). I don't think it is the ECT (engine coolant temp sensor) or the Cylinder Head Temp Sensor. Or the VSS or the MAF sensors.


The electronically controlled fan clutch is controlled by the powertrain control module (PCM) based upon requests for airflow to cool the engine, transmission and A/C condenser. If no cooling is required, the electronics permit the fan to spin at a slower speed yielding improved fuel economy.
-------------------------------------------------------------------------------------------------------------------------------
Inoperative or damaged:
  • Electronically actuated fan clutch
  • Electronically actuated fan clutch controller
  • Wiring, connectors, relays or modules
  • Engine Coolant Temperature (ECT) sensor (4.0L SOHC)
  • Cylinder Head Temperature (CHT) sensor (4.6L [3V])
  • Mass Air Flow (MAF) sensor
  • Vehicle Speed Sensor (VSS)
  • ----------------------------------------------------------------------------
If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).
Retrieve any DTC Codes (Diagnostic Test Code). Autozone will do for free.

--------------------------------------------------------------

The cooling fan clutch actuator valve controls the fluid flow from the reservoir into the working chamber. Once viscous fluid is in the working chamber, shearing of the fluid results in fan rotation.

The cooling fan clutch actuator valve is activated with a pulse width modulated (PWM) output signal from the powertrain control module (PCM). By opening and closing the fluid port valve, the PCM can control the cooling fan clutch speed. The cooling fan clutch speed is measured by a Hall-effect sensor and is monitored by the PCM during closed loop operation.

The PCM optimizes fan speed based on engine coolant temperature (ECT), engine oil temperature (EOT), transmission fluid temperature (TFT), intake air temperature (IAT), or air conditioning requirements. When an increased demand for fan speed is requested for vehicle cooling, the PCM monitors the fan speed through the Hall-effect sensor. If a fan speed increase is required, the PCM outputs the PWM signal to the fluid port, providing the required fan speed increase.

I am not sure if the radiator fan is working on my 92 v6 camry its not over heating but never see or hear the fan running is there a fuse or relay that might have gone out. I cant even see any wires that...


The radiator fan in the 92-95 models of V-6 Toyota and Lexus vehicles is a weird design. The fan is not electric but runs off the power steering pump. The power steering pump moves fluid through hoses to the radiator fan, thereby creating its rotation. A sensor monitors coolant temperature and signals a solenoid on the power steering pump when more or less cooling is needed. The power steering pump then speeds up or slows down to provide more or less fan speed.

This system seems to work pretty well. However, there is a connector that goes to the power steering pump that is critical to proper operation. In engine work this connector often gets overlooked when reassembly is done. This results in the fan running at constant speed and not increasing rotation when more cooling is needed. This becomes a problem primarily when the car is idling or moving at a slow speed.

If your car is not overheating in these situations, the fan is probably operating okay.
