Question about 2002 Acura TL 3.2 Type S
Fan turned off and will not come back on. Fuses not broken.
The fan is located behind the glove box, above the passengers feet. The 2 most common failures are the blower motor and the blower resistor. This system is a switch to ground setup. Unplug the blower plug and see which wire is hot, it should always be with the key on. With the car running and the fan switch on, hit the blower with the palm of your hand. If it comes on, it is bad. the brushes wear out. Also you can unplug the resistor, and ground the output wire at the blower, or resister. to see if it works.

General Troubleshooting Information
How to Retrieve a DTC
The Climate Control Unit has a self-diagnosis function. To run the self-diagnosis function, do the following:
1. Turn the ignition switch OFF.
2. Tu rn the fan switch OFF, the temperature control dial to MaxCool (60.F or 18.C), and the mode control dial to Vent.
3, Turn the ignition switch ON (ll),then press and hold the recirculation control switch. Within lO seconds while holding the switch down, press the rear window defogger switch five times. The recirculation indicator blinks two times and the A/C indicator comes on, then the self-diagnosis will begin. About 15 seconds later, the self diagnosis will finish and the Ay'C indicator goes off. lf there is any problem in the system after finished self diagnosis, the recirculation indicator will blink the Diagnostic Trouble Code (DTC) 1 through 13. When problems in the evaporator temperature sensor circuit are detected (codes 14 and t5), the A/C indicator will blink the DTC. lf no DTCs are found. the indicator will not blink.
Resetting the Self-diagnosis Function
Turn the ignition switch OFF to cancel the self-diagnosis function. After completing repair work, run the self-diagnosis function again to make sure that there are no other malfunctions.

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.

I have just purchased this car in the winter and found that the A/C was not blowing cold air. I am one month past warranty. I was told the same about the compressor not engaging. There is a charge as well and the Freon was drained and retested. Do yourself a favor....I have had the A/C clutch and Stator replaced, then the compressor, and now after $1000 (not including the charge of $1500 for compressor replace)I still have no A/C. It turns out that now the dealership has informed me that there is a blockage that cannot be blown free and the entire dashboard must be removed and a valve and the filter must be replaced. The blockage caused the clutch, stator, and the compressor to blow due to the Freon trying to be pushed through the blockage. The total cost to the job is $2,300 and the dealership ended up keeping my car for 1-1/2 weeks. Save yourself a lot of time and hopefully money and bring this to the attention of your repairman. Most of the time took them trying to isolate the problem. This sounds like a common occurance in the 2005 RL. I hope you have better luck than I did and hopefully save you some money.
