Hi. New here. Looking for assistance for my grandmothers Odyssey.

Problem is that the front AC doesn't blow air very hard.
Rear air blows really good. Moves a lot of air.
Cabin/Outside selector doesn't change the flow of air.
I can hear the blower motor in the dash when the air is on.


Tested resistor.
Part 1 -How to Test the Blower Motor Power Transistor (2001-2007 Honda Civic)
Pin 3/4 provide 1500 ohm.
Diode test on pins 2/4 provide a reading of 445.
This was with the red on 2 and black on 4.
When I swap those, red on 4 and black on 2, I get no change or the number 1.

 

Make sure to check the relay that controls the AC compressor clutch. That relay and also the AC condenser fan relay are know to fail and cause AC problems. I had this happen in my 08' Odyssey, after confirming it was a bad relay, I just picked up the part from my local dealer for about 20 bucks, but they can be had online for cheaper if you can wait on it.

 

Thanks for the "speedy" reply.

I have already solved the problem.
