Something odd happened to me yesterday which I have never experienced.

I had shut off my GS400 with the AC on. I restarted some days later, and although the AC and other buttons were lit, the fan was at 0, not on at all. It was left on Auto, and usually the fan goes to its highest before regulating the inside temperature.

I pressed Off, then Auto, and still the fan did not go on, till I pressed the manual settings.

I shut if Off again, being concerned, drove for a bit, then decided to give it a try gain, pressing Auto, and it then began to work as normal, the fan immediately went on.

Any ideas what could have been wrong or what is about to break?

Thanks

 

first make sure connection (plug) to the blower motor isn't loose. it hangs down by the kick panel on the passenger side under the plastic. has this ever happened besides this one time?

 

has never happened before to my experience, maybe I await the next event, or hopefully it doesn't happen again
