I do not have air coming from any of my vents. There is no sound coming from the blower when I turn the heat on.

So in fact you have no blower fan making the noise or moving the air. This is an expensive part, but perhaps we can find some things to check.

The RAVE electrical manual shows that Fuse 7 would be good to check. The power goes thru a relay, which has connector C153 on it, pix attached. The relay puts 12 volts to fan, but then fan is switched by another relay with connector C901, and the power transistor at C858 varys the speed of the fan. They all have to work for fan to behave.

 

Thank you, I checked the fuse already but none of the other things you mentioned. I will check them out.
