XJ Blower Motor resistor pack

[Tanner]

Looking for some experience with the XJs as far as the resistor pack for the heater blower. I had changed the blower and resistor pack in the jeep after it had blown earlier this winter (Blower was working on max air but no lower settings) I replaced the blower motor and resistor and everything worked fine. After the big wind/snow last Friday, when the jeep was started, the blower would not turn at all. (Even on max.) I pulled it into the garage and let it thaw out. The heater worked after that on max only so it seems the resistors have gone again. Both the first time and this time it seems the blower/heater ducting gets full of snow with the wind. From what I can tell there is no cabin filters on these units and suspect the water in the system is shorting out the resistor packs. Wondering if anyone else has this experience and knows of a fix or if there is another reason the resistor pack has gone twice on me. Thanks in advance.

When you replaced your blower motor did you silicone it in? If not water/snow/small children can get into the ducting as the motor sits in the engine bay. The blower wheel sits right in the ducting, slightly upstream of the resistor. Any crap that seeps its way in via the blower motor mount gets blown right onto the resistor. Happened to me when the seal broke down and started leaking. Filled my ductwork up with water, started leaking on the passengers' feet.

Don't test your blower speeds without the resistor in the airstream. It will burn itself out in about 10 seconds. Ask me how I know.....
