Hi,
I have a 2014 Latitude Cherokee 2.4L. Lately the blower has not been turning on intermittently, now it won't turn on at all. I have codes B10EA and B10E9. I checked the fuse, it seems good. If I apply 12v direct to the blower it spins. I'm checking voltage at the 4 pin connector that plugs into the blower resistor.
4 pin connector:
small blue/green wire
small blue wire
large gray wire
large black wire
Here is what I get at the connector with blower and resistor disconnected:
with fan at 1 (lowest)
small blue/green wire about 3.8 volts
big gray wire about 1.6 volts
with fan at 7 (max)
small blue/green wire about 1 volt
big gray wire about 1.6 volts
not seeing any voltage (maybe .02 or so volts sometimes) at the big black wire or small blue wire.
I've bought a new resistor and blower motor but no change when installed in the jeep.
Are these voltages correct? or does anyone have any ideas of what else to check?
-thanks
Nathan

After joining 4 years ago, it's good to see you finally post.
However, you do not have an XJ. XJ production stopped in 2001.
I believe the correct forum for you is here:
