Have a 2008 is250....randomly my air will not blow from vents top or bottom no a/c or hot air....i can hear the fan kicking on under the hood but nothing comes out the vents...already replaced the blower motor under the glove box...not sure what else to check? It will work fine for like 6/7 days then stop working for a day, then will work again the next day for 6/7 days and stop working for a day again.

check fuse/relay

I’m pretty sure when i changed the blower motor it came with the relay built in unless there is another one. I’ll have to check the fuse.

i replaced fuse, relay and motor blower still will not blow any air with a/c on or off. And this time it’s actually not kicking back on after a day usually it will come back on the next day.

bez88hlb - maybe try dropping the blower motor (which is pretty easy) and see how well it spins when you turn on your heater or A/C. There could also be some debris in there possibly blocking it.

I am having an issue with my blower motor - not working at all. Can anyone tell me which fuse it would be and where it is located?

I looked over all the fuses in the fuse list here https://fuse-box.info/lexus/lexus-is...006-2013-fuses
but all the ones that seem possibly related to the blower motor, have other circuits using the same fuse - and everything else is working fine in my car so that would indicate that none of those fuses are blown.

I checked and don't have any power to the blower motor power wire. So would love to know which fuse to check.

im pretty sure it’s something electrical/wiring at this point taking to a shop today cuz it seems like whatever the issue is is now permanent since it hasn’t kicked back on for 3 days...I’m not sure which fuse would be for the blower itself i changed the fuse and relay for my a/c comp just to see if that helped.

The issue sounds more like servo issues in the HVAC systen. Search on the forums. For AC servo issues. You'll get a better understanding on how they work.
