Did you get through with this issue? Got a similar problem and looking for possible solutions after wasting money on reputable ac technicians

Hi,
My 2012 Sylphy (B17) is not pushing air out any vents. Usually when the AC goes on a noise is heard and the vents blow. Now it does not happen. At various points below the dash the air is cold. The rear vents have some airflow.
Research shows it is the vent position control. Can anyone suggest someone who can check this?
Thanks.

Sounds like the blower resistor or blower itself.

Compressor and blower actually working. Blower changes speed perfectly with the speed control on the panel as it always did.

But can u suggest someone, preferably around St. Helena/ Trincity, to check this ASAP?

issue-- works perfect on mornings and night, unless the car is moving it blows warm especially around midday
carried it by an a/c guy, said it needed topping up and oil...did that
now pressure, blows hot all the time with the weird probably ac gas smell through the vents

any ideas?

Smell through vents sounds like a leaky evaporator.

Hey guys. Having a problem with my tiida a/c. It works fine when I put it on but if I stop anywhere an leaves the car running in park, it stops blowing cold when I start back driving. It only starts working again if I cut off the car then start back. Any ideas?

Check:
Engine fan
Engine fan belt
Engine idle speed when AC is on
AC fan control
AC fan control relays

Engine idle speed when AC is on
AC fan control
AC fan control relays

The fan seems to be running normal, the fan belt was changed last year and feels stiff enough, engine idle speed is about 800 rpm with the ac on. May have to look into the fan control and relays then.

Good day 2nrs,

Any chemical foam or spray available to clean the evaporator/HVAC box without taking the system apart? Trying to rid of a musty/smoke smell

AFAIK there is no chemical spray that you can use to clean out the evaporator .

if youre trying to get rid of a musty smell there are some places that can insert a long tube into the vent and inject pressurized hot steam to kill the mould and bacteria that grows.

the downside is you will have to change your ac filters afterwards - i think they would have it.

if that doesnt work ...next step is to scrap the HVAC unit and physically clean it out ..

KOOL-IT® by Lubegard
Contaminated air conditioning and heater/ evaporator cores can cause foul smelling, health threatening mold and mildew deposits. Use KOOL-IT® super foaming action to remove unwanted smells and stains from your vehicle's HVAC system. WORKS GREAT IN ALL ELECTRIC VEHICLES TOO!

Saw this product on other forums. There is an official Toyota branded kit also called Toyota A/C Refresher Kit. But I ain't a technician so I have no idea if it's just fancy marketing.

Worldwide trading the dealer for Wynn's also had a product years ago for this purpose. Not sure if they still sell it locally.

Worldwide Trading is still in existence? They were originally in St. Joseph and then they were in Cunupia.

With respect to getting rid of the musty smell, there was a product by Mothers being sold locally, Mothers Odor Eliminator and Refresher.

You would put the can down in the footwell, put all the windows up, turn on the a/c, activate the spray, and leave the a/c running until the spray runs out and a for a few minutes afterwards.

Radiator fan not coming on without the ac on, compressor burned out and locked up, the Ac control button not working ie orange light came off and the switch does nothing after compressor changed. Y11 AD.

Check the fuse. Control circuit seems to be dead. Is the new compressor clutch engaging when you switch on and radiator fan comes on? Or radiator fan coming on was after comp lock up?

Its a situation where no time with work so my ac was always on so the fan wasn't a issue. Now it is so I'm sorting everything out, ac man sending me by a electrican going there today. I'll update on that

iashtonramdeen · Postby **iashtonramdeen** » August 13th, 2024, 3:30 pm

It sounds like there could be an issue with the wiring or a relay after the compressor change. Make sure all connections are secure. If the fan and AC controls still aren’t working, you might want to have a pro take a look.
