Question about 2002 Acura MDX
Sound like a problem with the a defective transistor / resistor. If the A/C is out in
your Acura MDX and the charge system and fuse checks good, a new transistor will likely
solve your problem.
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.

Turn the AC on/off couple of times randomly.Then check.If same problem.Try adjusting the temperature setting to proper cold.But if still the same problem. Then get the ac pressure tested.The ac pressure test will let you know if there is any kind of leak in the ac cooling system.If there is a leak of ac cooling refrigerant then this can be the reason. If the ac refrigerant is checked out low then this can be the one reason,get the refrigerant recharged then check out.If still the same problem then the compressor needs to be checked.Is the compressor turning on or not at all turning.If its not turning on then the compressor relay needs to be checked.If compressor relay checks out ok then its faulty compressor,.Also check out for any kind of vacuum leak.Get all the vacuum line and vacuum hoses checked and confirmed that there is no vacuum leak. Also check your ac cabin filter .If its blocked by dust and clogged it will not let the ac run.
The filter isn't too much of a challenge to change actually. Shouldn't even require any tools.
Basically, you grip the bottom of the glove box housing and start pulling it away from the dash panel. The whole assembly is held in by 10 spring clips that will release. Disconnect the two wire harnesses that go to the trunk lid main switch and the glove box light and that's it. The filter holder is now accessable and you pull it out of the slot, replace the filter and reinstall the holder into the housing. Replug the trunk lid main switch and glove box light harnesses and then align the spring clips to their slots in the dash and push the glove box assembly back into place. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation

If the a/c in the front and rear is not blowing cold air then the r134a refrigerant pressure may be low or leaked out.
Also, if the fan doesn't blow in the front, I would check the fuses for the a/c to see if any are blown.
If that's not the problem, the fan motor could be bad, or the wiring to it, or the relay for the fan could be blown.
