2000 Mazda Protege A/C will cool air but airflow will randomly start, stop, and change intensity. Checked fuses, relays, and front cooling & additional A/C fans and ask seem to be working, perhaps a blower or blower resistor problem?

Sounds like the blower resistor. It can make contact and break contact as it heats up and cools down. This would cause sudden changes. If the airflow gradually changes speed, it could be the blower motor binding, such as if the motor lubrication has become very old or used up.

SOURCE: Acura MDX A/C won't come on

I went to an Acura dealer to buy the transistor for the rear A/C unit. The service advisor told me that the problem with the front A/C was probably due to a defective front transistor / resistor. I bought that part too.

The front transistor is located next to the blower motor under the dash on the passenger's side. It is secured by three or four small bolts. The one on the bottom left is very close to the carpet and the most difficult to get off and put back on.

The rear transistor is located behind the carpeted trim panel on the center console (driver's side). The carpeted trim panel is secured by clips only - there are no screws, so remove it carefully starting at the side near the accellerator pedal. Once the panel has been removed, reach inside a small hole in the metal frame to access the rear transistor. It is removed by twisting it and pulling it out. The hole in the frame is small and you might find pliers helpful.

After replacing both parts, the front and rear A/C are working. Apparently these transistors are common failures. If the A/C is out in your Acura MDX and the fuse checks good, a new transistor will likely solve your problem.

SOURCE: fan cooling problem. which and where is the relay or fuse for the cooling fan? I need a diagram showing me what the relays are for and what they operate.

I have the original owners manual, and it says that there is a fuse (No 16) and a relay (No 10) for the blower motor. I've same troubleshooting right now. If you wants send me a email to luisfernandovaldes@hotmail.com to send you a scan imagen of the fuses diagrams.

SOURCE: where is the fuse or relay for the cooling fan in

You have to refer to your owners manual or an after market service manual for fuse locations but that is not the issue. There is a sending unit screwed into the block with a temp sensor that closes the circuit on the ground side when the cooling system reaches a specified temperature. There is a fuse between the hot side and the fan for over current protection (see manual). A bad sending unit is most likely the culprit. Measure the resistance or continuity when the engine is hot from the sending unit body which is grounded to the block, and the output terminal or black wire running to the fan motor. It should be closed or read less than 0.5 Ohms. If it is open or very high resistance replace it. Good luck to you. I hope thishelps

Where can i find the fuse for the cooling fan for a 2000 mazda 626


There should be two fuses for the cooling fan relay in the main box near the battery.
You could have air pockets in the cooling system which would affect the temp sensor.

No, the fans have separate relays. You have to use the wiring diagram to sort it out. The pcm turns on the cooling fan relay with a ground signal on a purple/black wire when the temp sensor signal rises too high.

My 2003 mazda mvp starts to overheat when in ideal or stopped traffic. What could some of promblem be? thank you PC


Hello PJ.

Usually when this happens the electric cooling fan on the radiator isn't coming on.
As you are moving air is going through the rad cooling it. When stopped or moving slowly there isn't enough airflow so the fan should come on.
Possible problems are a blown fuse, something jamming the fan blade, bad motor for the fan, bad wiring connections, bad relay or a sensor not detecting proper temperatures.
If the fuse is blown something caused it to do so, most likely a jammed fan or shorted out motor.
To begin, check the fuse, make sure the fan isn't jammed up with something, check wiring for shorts and bad connections.

There are the possible problems as you have asked.

Thank you for using FixYa.

1999 mazda protege when starting of at a slow speed the car starts to buck and o/d light will flash


The tube after the air filter might be cracked (Fix it). Next the you will see the Mass Airflow Sensor. Unplug that and see if you car runs differently (better while driving, worse while idling). If so then it is definitely the MAS (Mass Airflow Sensor). There is actually a recall on this part (at least, for the 2000 Protege). Also, try cleaning it and plugging it back in. Change spark plugs (OEM only, nothing fancy). Also, some gas does this worse than others.

2001 Mazda Protege cooling fan or thermostat


I am realizing that the cooling fan in this car is very important. It has two in case you didn't notice. The driver side fan motor is bad in mine and the only result is poor air conditioner performance in stop and go traffic. It's fine at high speeds. I would think the thermostat is likely the culprit in your case, but if the fans are not working at all, you should get those replaced. The motors may be bad in both, which could definitely cause overheating. I've been researching prices and you should be able to get the parts for less than $100 each and installation is just a couple of bolts on each assembly.
