    but then if it ran all the time, even when the car is cold, this theory would fail.

    have you checked for short circuits in the cabling to earth. If the fan is switched in the earthy side,then a short to earth would cause the symptom. Unplug the Fan relay, and disconnect the fan. Check the cabling for any shorts to chassis.

How do you replace the blower motor resistor in a 2001 toyota echo, blower only works when set to full speed leads me to believe it is the resistor from searching information, just need to figure out how...


The resistor pack is almost always close to the blower. It needs air moving across it to keep it cool. It is usually installed into the duct with two small screws. It has a connector with about 5 -6 wires, and is about 3/4 inch wide, and about 3-4 inches long. Some can be a little difficult to get out due to clearance, and their shape.

Also, it could be the fan speed switch that's giving you problems.

Bought 2001 Lumina.. head gasket was leaking. fixed that n noticed cooling fan motors were not running. Replace all 3 relays n ect n fans started working. Drove it two days n it started runnin hot pulled...


I had a similar problem. Is your temperature gauge pegged to the right as very hot? Or reads always cold, even when hot. If it is a 3100 motor their is a coolant temperature gauge sending unit under the air breather intake that is right next to where you replace the thermostat.

Get a haynes repair manual at a parts dealer, Amazon, or your public library.
On the Chevrolet Lumina, Monte Carlo, & Impala FWD 1995 to 2005 it's under section 3-8 on page 3-6. It goes into great detail, and it's too complicated to explain here. If your sensor is bad, but the wires and fuses are good then the fans won't run.

Your second fan only runs when the air compressor is turning, If your ac compressor is not running then the sensor will not have the passenger fan run.
You have to see if the fan motors are good and then the wiring is good, and no fuses blown. You might blow fuses so have extra blue ones if I remember right. Recheck fuses after testing.

I have a 2001 Echo with 147,000 miles that has always run beautifully, and now suddenly, with no warning or sounds of any kind, it won't start. We have run computer diagnostics, all showing no problems...


does the vehicle have theft lock on it? i had a fam. member this week go three days without his vehicle that ran awesome too. using the same key he always did and all... i went and looked at his vehicle, noticed the theft light would come on when i put the key in the ignition, so i asked him about the key, and he said thats the one he always used, so i had him get me the original key for the vehicle, ( the one he was using he had made, and put the original up) he got it for me i put it in the ignition and the vehicle started right up.... there is a code in the key that the vehicle reads and if its not there the vehicle will not start.. Like i said he had used his key he had made, the whole time he has owned the vehicle, and it just now decided to do it.. dont know why... but hey its a thought.. hope this helps

What is required for a 2001 toyota echo tune up?


I also have a Echo and would suggest:
Air filter, spark plugs. If it is still sluggish I would then replace the upstream 02 sensor. The fuel filter is apparently lifetime so it should be okay.

2003 Saturn Vue electric fan always running


Check the fan relay, probably in fuse box in the engine compartment. Check owners manual to be sure. I have seen these melt causing fan to run all the time.
