after shopping,,,tried to turn on the AC... nothing happens.... was working in the morning but now the control panel light comes on indicating fan speed and temperature and stuff... but no air come out of the ac....... anyone experienced this or know what might have happened? i hope its just a fuse and not the compressor......wonder how much it would cost

Search dude, unfortunately there is TONS of info on this due to so many people with the problem. I hope for your sake that it isn't the compressor, because that is $$$$.

thanks, just posted on one of the forums... one guy mention if its compressor it was as high as 1800 bucks.. is that true?

It's up there, but I don't think you're having the same problem. Air will still blow through the vents if the compressor is blown. If you don't have any air blowing through the vents, it sounds like an issue with the cabin air fan (or whatever it's called). That would be an easier fix for sure.

Howard911s

Air will still slow even if compressor is broke? god i hope so....

Right now all the fan/vent in the cabin. NONE of them have air coming out of it.........any wild guess what this might be? thanks...

Geez that's weird, I don't think I've read about that specific problem on here yet. Maybe it isn't the compressor after all.

as long as it wont cost more than the compresssor problem ...... 1800....guess this is where my holiday overtime goes....

I don't have my service manual handy, but I bet it's just the cabin fan. I don't think it's on its own circuit, so I don't think it would be a fuse. It's not a complicated part so it wouldn't be that much to replace. I think it would be one of those things where the labor would be more than the part, but in either case, it's probably a couple hundred bucks tops.

It's best to just have your dealer troubleshoot it.

check your fuse, relay, and wiring to the fan motor or around the AC system... you say the fan doesn't work right? or is it not gettin cold?

Howard911s

oh its not blowing ANy air at all.. i turn it on, i can hear some motor or something whining under the car or under the hood.... then it stopped, no air at alll...........no hot no cold.. just .. -____- no movement. sigh

i would check the fuses and relay to the fan and anything around it to be sure your car should still be under warranty right?

Fuse 21 in the underhood fuse box is dedicated to the blower motor only, so that's the first thing to check. There's also a relay in the U/H fuse box. If you've got power available at the motor, it's either the power transistor (which provides a variable resistance ground to the motor to vary it's speed), or the climate control panel (which sends a signal to the transistor) or a wiring problem in between. Of course it could be the motor itself as well.

Don't think we've seen the transistor fail often on the TSX, but I have seen them fail on newer Civics/CRV's/Elements. Long story short, if you don't have the knowledge yourself, you need to have someone who does diagnose it properly.

thanks for the post on fuse and transistor.... i know nothing about electrical on cars, but hopefully those cost less than 1800 dollars compressor?

my car is out of warranty. its an 04 but has 62500 miles

Howard911s

its fixed!!!!!!!!!!!!!!!!!!! so happy! went to this shop i went to over 14 years, theycheckd it to be the transistor resistor... but they dun have the parts, so I went to Thomas Acura who happened to have it in stock... drove back, they poped it in, done! 120 bucks total!!!!!!!!!!!!!!!!!!!!!!!!!!!!! wheeeeeeeeeeeew all is not lost.....at least i get to keep some money for christmas.

Thanks all for the valuable opinion

PS: they say this has been happening periodically on honda and acuras....they received some sort of bulletin about ac problems... but no recall..

jlukja

transistor resistor?

Glad they were able to fix it relatively cheap, Howard.

Typical

Glad you got yours fixed cheaply and quickly.
