Well if you have verified that power is going to the blower motor and it will not turn on then the motor has gone bad.  This is assuming that you checked for voltage where it enters the motor and that there was only two wires going into the motor (1 positive and 1 ground).  If there is more than 2 wires entering the blower motor, check for voltage on the others.

Getting heat in the heater core,heater door are opening, but no heat coming out the vents,help thanks


It sounds like the blower motor is not working. If you don't hear it running when you switch it on, check the fuse first. If the fuse is OK, you will probably need a new blower motor. It could also be a faulty fan switch or blower motor resistor. Once you remove the blower motor assembly, you can test it by putting battery voltage across the contacts with jumper wires, making sure to get correct polarity. If it does not spin, it should be replaced. If the blower does work when removed, the fan switch is probably at fault. The resistor is usually indicated when the fan works only at certain switch positions, but not all.

2003 jeep, grand cherokee no heat or blower


this sounds like the blower or switch is bad. to test blower, first check the fuses, then if it still does not work, run 2 wires from a power source 1 for positive and 1 for negative(ground) disconnect connector at fan motor and try these wires to see if it runs. if not replace fan,if it runs on wire but not from switch, replace switch. or check wiring carefully.

you need to change the resister block for the fan. it is located on the heater duct near the fan... there is a connector on it and two or three screws holding it in.

The blower doesn't work for heat/defrost


If you have Automatic Temperture Control then you will need a blower resistor module which could be around $100 to $200. If you have a manual temperture control then it can be just a simple $20 blower resistor.
