the buttons and all work fine.. i'll hit the mode button or whatever and nothing happends? anyone know why no air is blowing

LScowboyLS

no air blowing can be the following:

1. blower fuse and/or relay
2. blower motor (give it a sharp whack and if it comes to life, it's bad)
3. ECU issue
4. blower resistor
5. the control panel and/or its circuit board

get a 2 day membership to to the factory's Toyota Information System for $15, and download the appropriate factory service manual section for your model year and go through the troubleshooting steps.

1998 LS400 - My A/C clutch is failing, but up until today the A/C had been working, just making bearing noise. Today I had the blower motor on just blowing air (not A/C at the time). Hit the A/C button and the blower motor completely quit. Found that the fuse under the dash had blown and replaced it, still no blower. I know there is a relay and I think it is a small black cube in the fuse panel under the hood (marked heater on the panel diagram?). Has anyone heard of a failing A/C clutch taking out the blower motor when the A/C is switched on? What else should I be looking for to just get the blower motor working again? Thx
