Blower motor has quit working
I am having a similar problem. Last week My heat and ac both just stopped working. we replaced the blower motor resistor...it still did nothing..until this morning it started blowing (BOTH heat and air work) is BLOWING constantly now on one speed...what could this be?
On all speeds, is it dead sounding or only no air flow???
wow no symptoms posted only this goose chase deal.
use the scan tool yet? see all DTC errors.
2008 cars can report most cause of lost power etc,
not scanning, invites expensive gue$$ing.!!
HVAC 101: (
gdoes the motor have 12vdc on high? at connector to it>?
on all speed's (now that is a KEY FACT there)
calibrate damper:
Use this procedure to ensure that the A/C-heater control is correctly calibrated to the blend door actuator. If the calibration is not correct, the heating-A/C system may experience a condition where full heating or cooling capabilities cannot be obtained.
Many steps can not be done with out a real jeep scan system.
sorry, cant.

You have to take the glove box off and it is right behind it, need a #20 Torx to take it replace it. The glove box is the hardest part of the job, I just replaced mine on an 05 Grand Cherokee but it didn't fix it for me, was well worth the $8.60 to try though.

The HVAC Blower Motor Resistor needs to be replaced. It is located in behind the glove box. You have to remove the glove box which is easily done by releasing two clips located on each side of the compartment door. Then slide the cover to the right and the cover will come right off. I just had my replaced today and it only took the garage 10 minutes to install the new one.

It is not the relay, you have a defective bulb on the side that is not.
