Hi I have an 1999 V70 This morning the a/c lights came on but no heat would come thougth the vents.I had it set to auto so I adjust the switch up to the highest setting and still no heat.?I ve checked the 25a a/c fuse and thats fine and ive checked the a/c monitor fuse and thats fine as well.could it be the fan blower thats packed in.???

Help please.

 

I would say either blower motor or resistor.
