So I started my 04 today, and when I turned on the AC (auto) it started blowing hard then stopped totally then on again, it actually does this is 5-10sec intervals. Then about 3-5min into the drive it stops and AC functions normally again. It seems to only do it when cold or at beginning of startup..
I was thinking possilbe blower motor? Someone said expansion valve, but I don't think that would actually cause it to stop blowing.

Anyone experience this?

 

Anyone?

 

AC motor switch / transistor / resistor.

 

#15 - 79330-S6M-941

 

when that happened in my accord it was the resistor.

 

kind of crazy how they still use a resistor like that 22 years later (bad resistor in my 89 civic)

 

I had the same issue and took the car into the dealer and had the blower motor replaced under warranty. When I told the service dept what it was doing they just ordered a new blower and said its a known problem.

 

Thanks guys, I wonder if I should do the motor or the resistor 1st? I guess I'll to the cheaper of the two 1st. Thanks for the input.

 

I'll try the resistor first, looks to be right behind the glove box??

 

No reason to replace a whole engine if it only needs an oil change, know what I mean.

You can access the transistor below the glove box (not behind glovebox), just remove the lower cover (should be 3 clips and a release pin in the back). Disconnect the 4 pin connector and replace the transistor switch (should be a couple of fasteners in place). Put it back together and you're done.

 

^^ got ya..Thanks for the info. I ordered the resistor from my buddy at Honda this morning (as it matched over to Honda part #).
Looks like I'll be putting the new one in tomorrow afternoon, I'll post my results. Hope it's not the blower motor..

 

Thanks Majofo !!! Looks like the resistor fixed the problem!! $42 dollars and about 3min to change, can't be much easier than that!!

 

Thanks for telling us the final fix.

 

Glad it worked out Schul!

 

Exact same issue here. The past 2-3 weeks, when I first get into my car I can hear/feel the blower turning on and off in spurts. Then after a few minutes it all goes back to normal. Today when I got in my car at work....nothing....said f'it and started driving home (with my seat heat on high) and about 4 minutes later it comes on and works perfectly.

Guess I will be calling my local Acura and Honda dealers in the morning to find their pricing and see if I am lucky enough to only have this be my issue.

 

That's how mine was acting at first in the CL, then the A/C quit working period.

It was the resistor on top of the blower motor.

 

I hate dealer markup some days. $53 list, $64 at the local Honda dealer, $68 at the local Acura dealer, and $40 from Delray. Guess that is the price you pay for having it in stock and available immediately.

 

And fixed. Less than 5 minutes to replace the transistor. I spent more time looking for the "clips" that holds the lower panel in place before I realized you just pull it down. Two screws hold the module in place. My drive into work this morning was nice actually having a functional heating/defrost system.
