Maybe the fan itself is the problem, it could be a carbon brush problem,,,try to tp the motor while it is on, if it runs, then the brushes are short already...

Can't start my 2001 mdx with remote starter screen showing fuel average heating fan comes on only when I press brake padel rear wiper on off it self


try removing fuses on passenger side kick panel and cleaning the contacts and reinserting for problematic issues, suggest duing to all fuses, mdx 2001 has known issue with fuses becomming corroded or dirty without actual evidence, 90% of the time removing the fuse and reinserting after cleaning or even repeatedly removing and inserting will solve many issues on that year of the mdx, if problem persists, suspect faulty switch or modules.

AC/Heating fan control in center consol.


honda pilot and acura mdx share a lot of the same parts. The rear blower motor resister is known to go out after a while.
http://www.acuraworld.com/forums/f8/mdx-back-seat-blower-doesnt-work-71111/

Either buy the honda part 80 bucks, or you can buy a resistor and fix it yourself for about 10 bucks. Details in the link above.

Blower fan not working


its all in the glove box, open it and read the operators guide.
see fuse section.
buy one or get one free on line, google for it.
its also in the FSM. book.
or at alldata.com

The Fans are controlled via Relay, and the PCM on newer cars controls that in complex ways.
the front fan is called the A/C condenser fan the rear fan is RAD fans.
the FSM coves the tests for each and ALL steps to find what is bad.
it only takes the FSM and DMM (voltmeter ) and 15min work to see who an what is bad.
(so we look at the relay, fuse good)
we check all 4 pins with a voltmeter. bingo we know.
ask more questions, can show drawings, after fuse are good.

What fuse is speed control


First, Please review these articles:

Where's The Fuse?

What Else Could Be Wrong?

Then to answer the question you asked...

There are actually three fuses involved in your cruise control system.

> The first is the "Cruise Control, EAT ECU" fuse. it is Fuse #4 in the Underdash Fuse And Relay Box. it is a 7.5 Amp fuse. This fuse also powers the gauge assembly, the alternator control circuit, the Radiator Fan Control Module, the Intake Air Bypass Control Solenoid Valve, The EGR Control Solenoid Valve, The EVAP Canister Bypass Solenoid Valve, the EVAP Canister Vent Control Solenoid and the Heated Oxygen Sensor Heater circuits. If this fuse is blown, the engine will not idle, The alternator will not charge the battery and the transmission will not shift properly. In general, a whole bunch of stuff will not be working.

> Next is the "Backup, Metering Lights, Turn Signals" fuse. It is Fuse #1 in the Underdash Fuse And Relay Box. It is a 10 Amp fuse. As you can tell by the description, your backup lights, dash warning lights and turn signals will also not be working if this fuse is blown.

> Last there is the "Stop Light, Horn" fuse. It is Fuse #30 in the Underhood Fuse And Relay Box located at the right rear of the engine compartment. It is a 20 Amp fuse. As you might guess, your horn and stop lamps will also not be working if this fuse is blown.

The fan stopped working for the rear AC/heat in our 2003 odyssey. Checked 40amp suqare fuse under hood and it tested ok. Is there a fuse or breaker for the rear fan motor?


The large fuse you checked is for the rear fan blower motor. The fuse you need to check is for the fan motor relays and rear mode control motor. It is fuse No. 3 (7.5A) located in the driver's under dash kick panel fuse box.

If fuse No. 3 is blown and you replace the fuse and it blows immediately, you'll have to check the five relays and the mode control motor all located near the rear A/C unit in the right aft sidewall. Most likely, the mode control doors have become jammed and that is why the fuse blows. The doors shift air from overhead vents (cool) to floor vents (heat).

If the fuse is fine, the trouble is probably with the blower motor itself or the wiring to the blower motor is broken, or there is a bad ground.

Plugged in my car charger into the cigarette lighter and my navigation and radio shut off.


It sure sounds like a fuse may have blown, although the cigarette lighter fuse in most cars does not control the radio, and should have been able to handle the car charger without blowing. Take the lid off the fuse box, either under the hood or inside the car under the dash on the right side or left side of the car, and look for a blown fuse. Usually you can tell if they are blown by looking at them.....but you often have to remove them first, depending on the type of fuse used in your car. The inside of the lid may have a chart that shows which fuse controls the radio.
Good luck,

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.
