Anyone know how to test??

[AFT2008KK]

Hi Liberty Experts. 08 Ltd 1344xx miles. After a few more days of So-Cal rain. The a/c climate control isn’t working. Its an auto control. The fan control does not blow at any setting. Anyone have a schematic? Or know how to test?

Sorry can't help with any measurements, I have a spare KJ one but it's different.
All I can suggest is probing the connector to find the supply and following the wires to the motor, that should prove the supply is ok and allow you to put a test link in to prove that the motor is ok. If its anything like a KJ the resistor pack is a common fault.... and the reason I have a spare on the shelf, I hate cold cars!

Only had continuity between 2 of the pins. But can’t find any info on line.

I'd look at the connector on the car, as I said above, that will give you more information that a potentially blown resistance pack. If you can't find a 12v supply then check the fuses, on a KJ they are on the side of the dash in the drivers doorway, not sure on a KK though.

Done more trouble shooting. Power is getting to the blower fan. And when i apply direct power to + / - terminals on fan itself. No bueno. Doesn’t spin. There is continuity between the fan power terminals. So im betting on fan motor went bad. Thoughts?

what's the resistance value on the fan.

16.3

I am on my third replacement blower fan in my 08. The original lasted about 5 years. I replaced it with another Mopar and it lasted maybe 2 years. After that I have had two from Advance Auto Parts. At least they have a lifetime warranty, and they are easy to swap out. The current one has been fine for 4 or 5 years.

So, if yours has died, it will not be the first or the last time.

Actually it is the 1st time. Blue has been in family since new. Checked with. Father in law (original / prior owner) he never had an issue. Given dates on original parts i believe it. Im going to swap resistor and fan motor. Parts on order and will be here in a few days.

Oh yeah, guess what? The hood release cable snapped too. So had to order that on line. Never a dull moment.

Ill let you all know how it goes once i work on it next week.

As promised. Finally had an opportunity to sort it all out. Nee relay and fan motor installed = hvac working again. Thanks for the support. Pic of part #s below.

Nice! Glad you have HVAC again.

Nice! Glad you have HVAC again.

More rain on horizon. Having defrosters will be nice. Btw. New hood cable sorted too.
