Hi,

The AC blower fan seems to start at high speed and then stutters before it continuously runs as soon as the car is started. This has been happening for a few weeks now. This morning, it did the same but stopped blowing in a few seconds and would not turn back on . Once the car was restarted, the air flow stuttered and ran continuously thereafter. Has anyone had this issue before? I do have cold air coming in when the blower runs. Last year I had issues with the clutch set and stator and I had that replaced by a friendly mechanic for very cheap. Compressor is still the original one.

Any help is appreciated.

Thanks,
N

 

have you checked the relays

 

No I have not. How do I check those? you mean get a new one, plug it in and see?

 

Just found this under 2G. I'll use the procedure mentioned to check the relay tonight. https://acurazine.com/forums/2g-tl-p...ir-diy-775458/

 

OK. Relay seems fine. I even had a spare that I checked with. Same issues. Now my blower wont work at all 95% of the time. Any other ideas?

 

So you mean the fan blows on its own and doesn't respond to the controls? That can be the blower motor resistor

 

No. The blower cuts off after 10 secs and does not respond to the controls.

 

I just posted this on another thread titled "blower motor being finicky". It may help you...

Hi folks. Just for the ease of trying to find the right part, the part in question is called a "Thermistor", not a transistor. Some parts stores have it labeled as a "resistor" which more closely resembles the function. I have a 06 3.2 TL in which I replaced the thermistor at least twice and replaced a blower motor once. It is still acting finicky. One day when my wife came home and told me the fan wasn't working, I reached down and wiggled the electrical connector at the fan and it started to work.

As mentioned previously, the fan is under the glove box to the right. The thermisor is a suspect, but before you replace it, when the fan doesn't work, reach down and tug and push on the connector to the blower motor and see if that does anything. My wife hasn't had a problem now in 3 months since I did that. Maybe it will work, maybe it wont, but if it does, it's free...
