Why are my cooling fans for radiator running constantly?

The cooling fans are supposed to run any time the a/c is on in order to keep air flowing across the condenser. Your a/c will not work properly at idle if they quit.

My blower motor quit working changed blower and now it runs all the time even with key off worked fine before blower went out the fuse had also blown what could cause it to run all the time now

Most would say it is the Blower Motor Resistor or a relay..And possibly the dash heater control knob..However it is running all the time even with key off..This means it is getting power all the time from somewhere..It sounds as if wiring is crossed..Did you have to change wiring plug in connectors..?..

What does it mean when your heater /ac keeps running after the car is shut off

The most likely problem is the blower motor resistor/module is stuck on high speed. The high speed relay is fed power all the time. If it sticks the blower will run even with the key turned off. The typical fix is to replace the module. It can be found under the passenger side of the dash near the blower motor.

The MOST LIKELY cause of your problem is a bad blower motor. The next time it quits, look up under the right side of your dash and "thump" on the motor housing with your hand, if it starts blowing again when you do this, replace the blower motor.

NOTE: It would be easiest to go ahead and remove the lower trim panel from under the dash (even if the blower is working at the time) so access to the blower motor housing will be easy when it quits again.

Heater fan does not work

If you're talking about the blower motor under the passenger side dash then you can test it to see if it's functioning or simply not getting power. You can run a hot wire to it with the voltage it's supposed to get and see if it's working or test for voltage there. If it's getting voltage then replace the blower motor. I would suggest a book on your car. Good luck!

In 2002 Toyota Echo, I need to replace blower motor. There is also a resistor and a ''blower switch'' in a manual, but no explanation of the blower switch. Is this just the 'fan switch' on the dash. ...

blower switch is your fan knob on dash. resistors are located under pass side dash next to blower motor. on alot of cars the blower will work on high speed and not the lower ones- this is a tell tale way to tell the resistor is no good. if this happens again after replacing resistor- ive seen the blower motor shorting out causing the resistor to go bad- then you would have to replace both.(this usually dosnt happen, most often the resistor alone fixes the problem..
