Ac and heater do not blow
I have a 1995 xj .Hello out there. So my a/c and heater were working and now they have e both stopped blowing niether hot or cold. I have replaced the blower motor and the resistor and still nothing. I have checked fuse and relay and both are good. The compressor I have checked and it is not seized. Would really appreciate the help. I am trying to fix this myself so I can learn and save some money. Thanks

So it's the blower motor that is not operating? Do you have a multimeter or test light?
It's possible the switch has gone bad, or the connector for the switch that controls the blower motor speed. When the blower motors age, they start to draw more current and this puts a strain on the wiring and connectors. Occasionally this melts something.

I would suggest taking a look at the control switch again, make sure the connector is still in good shape. Have you checked for power (+12V and ground) at the blower motor?
