The AC in my bro's 2007 TSX stopped blowing air. The air is cold, because he can feel it when he's driving and it's on the external air setting, but the blower may be dead. I checked the fuses (30 interior, 21 engine bay) and now I'm thinking it may be a relay. Any ideas?

If it's a relay, anyone have the part #'s? Can't tell which one is the blower...there's a Fan, AC, and a vent looking thing...is it the fan or vent one for the blower? Any help is much appreciated!

 

Do a search for the other A/C threads. There are some relating to the compressor/condenser, and some relating to the relay. I'd look it up for you as I've had mine replaced twice, but I'm not home so I don't have access to my invoices. I did post the part numbers in one of the other A/C threads, though.

 

Found a link to the parts and part #'s. I can't tell which relay it is...is it the more expensive one or the cheaper one :/

RELAY ASSY., POWER (MICRO ISO)(MITSUBA) (39794-SDA-A05) $28.78

RELAY ASSY. (MICRO ISO) (39792-SDA-A01) $5.56

Thanks in advance!!

 

If your blower in not blowing any air, I would first check the power transistor located under passenger dashboard in HVAC ducting. (if you have a manual there is a procedure you could do to test it out and isolate the problem). I had an issue with blower not blowing any air at all and ended up replacing the power transistor taken from a junked, get this, Honda Civic. An Acura one is expensive for such a simple part. Here is Acura's part number 79330-SDA-A01 Transitor, Power. Hope this helps.

 

thanks, found the part number. i don't have a service manual. i can probably find the resistor, but does anyone know how to check? thanks.

 

just tried the power transistor, 79330 SDA A01 and it still doesn't blow air

 

You might also want to check your cabin air filter- perhaps it's clogged. I just changed mine today and it was dirty with < 2 years time since last replacement. If you haven't changed yours it will be due.

 

Might be the blower motor that went out. I just over heard another customer having that issue and said it was his blower motor that went out and was about $350 for the repair.
