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.

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

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.

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.
