Have already tried swapping some relays and nothing has changed living in AZ we need the AC for a little bit longer before the temperatures drop. AC light on controller is NOT flashing. Could it be the HVAC control display itself? Talked to Toyota parts the part number for my control display has been discontinued and nobody in the country has one and he said they were $1700 anyway so if that's the issue it's gonna have to be used

So you have no air blowing in the cabin - no matter what the temperature is? It just won’t blow at all - ie not just an ac problem?

It's probably your fan speed resistor under the dash. It's prone to failure.

These don't really have a resistor, more like a circuit board that has a sense line I believe. The original post is kind of confusing on what the issue actually is for the fan side of things.
 
Yes confusing, it could be something as simple as the fan motor needing replacing....or as mentioned a relay
 
Sorry about any confusion I just started a new job Monday and I'm busy as hell. And basically the air conditioner was running and then all the sudden just stopped any button that you would hit for a fan speed would not kick anything on pulled some relays switch them around nothing changed all the sudden family goes to take a drive and they say the AC is working and then again it shut off and then started working again. The fan is only a few years old. And it's sporadic with not working and then working again like something is loose or may be a relay that is stuck.
 
When air is not flowing "tap/bang" on the motor housing, from underneath the glove box.

If fan starts blowing..........it's the blower motor.

Mine is a 2008 T4R.......and I've replaced the motor twice.

Hope this helps.

Yep it's the fan blower motor I would never have guessed that was the issue as it's only a couple of years old. Maybe 4-5 Years old at the most the original one lasted a good 15+ years

I hope you are or did replace it with an OEM motor this time, 4 to 5 years for an aftermarket motor is pretty much normal!!

I know OEM costs a lot more...but as they say "buy once, cry once!"

Yep the one I originally Bought as a replacement was OEM for sure. Definitely did not last long unfortunately.

FWIW........my first replacement motor lasted about as long as the factory motor.

The second replacement motor is the same as the first......from Advance Auto Parts (CarQuest brand) that has a lifetime warranty.

Hope this helps.
