My AC/Heater fan isn't blowing but I can tell the heat and AC are working. How in depth is it to replace the fan/blower motor? Does it require taking half the dash apart like the heater core did? Or is it more simple and I could do it myself?

take it towhomever fixed the bcm and tell them to fix it

Sounds like high blower relay is bad

check heater/ac fuses first replace if bad..see if there is power to the blower motor connector if so reconnect and check ground wire for the motor.. if still no blow, take motor out and test for operation with 12 volt power supply(battery charger) replace if bad..good luck

The first thing i would check is the heater blower motor for power.If the blower motor has power then pull and wiggle on the blower motor resistors pigtail or connector but make sure the heater and fan motor and the ignition switch are turn on so you can here if the motor comes on. A lot of times these blower motor resistors get hot enough to melt the connector causing it to loose its connection.

This will help.Thanks.

Yes , it is possible that the motor or the speed control ahs failed so that the heat is not distributed. So what is needed is to check the fuse of the blower fan, if there is power to the fan motor and still it does not work then the motor can be faulty.

Does it work on all speeds, or has it only stopped on #1 speed for instance....the blower motor is located at the passenger side footwell...

Check the heater control switch,,,,,and the number of wires at the heater motor....Some motors have more than one winding...in which case there will be three or more wires going into motor..there can be burnout in those windings and will require a new motor....check the plug which attaches to the motor....can be bad connection...or at the switch.....but if there is only two wires....then the heater switch uses resistors to slow down the different speeds...and direct connection for high speed....and the problem is definitely the switch...

First check the fuse for the heater/ac fan. If the fuse is OK, you probably need a new blower motor. If the fuse is blown, replace it. If it blows again, you could have short in the heat/ac control computer, or the blower motor may still be bad. In this vehicle, the blower motor is probably less expensive to replace than the controller, and you can test the blower once it is disconnected by applying battery voltage to it (observe correct polarity). If it does not move when jumped directly to the battery, it is almost certainly bad.
