So ive read all of the post about the ac failure and where to check and everything is good, from the transistor to the blower motor its self, seperately everything works and i figured out that the black/yellow wire is the positive, and the blue/red is the ground..i have tested everything over and over and ive got good power and a good ground and the blower works when i put a 12v lead and ground into it..but when i connect everythhing together i get nothing,im so confused and frustrated can someone please help????

 

Did you Check the Leads and tested before connecting???
You cant possibly get readings with anything disconnected then Nothing with everything connected...

Check Motor Leads disconnected with a Volt-e-meter and turn it All the way to Cold (60°F) FULL AUTO. you should be getting a hefty +12v on the Black/Yellow.

 

lets start at point A

is the power connector in front of glovebox good? open and inspect for burning
very common problem especially in summer running fan of 5 all the time

the resistor (not transistor)-- you removed cover and its good,,has continuity?
no burns etc?

swap cabin fan relay with another relay of same color

 

reading post again,,you can jumper power to fan and it works
but not when put together--correct?

suspect main power connector,,
acura sells update part with longer wires to lessen stress
easy diy
heard as low as 8$ at some dealer,,to $15 at others for the kit with both sides of connect and wires attached,,splice and go

 

So i went to a mechanic withh the resistor and that was the problem, he fixed withh some soldering magic and it works fantastic now..thanks everybody for there input
