Blowing Resistor packs

I keep blowing resistor packs for my blower fan. The last one only lasted 2 weeks. Now all I have is high speed.

I've heard that this is an indication of the blower motor failing?

I'd appreciate any suggestions.

Thanks!!

Craig

Re: Blowing Resistor packs

IMHO, 'yes'

motor is drawing too much current.

Re: Blowing Resistor packs

What's the least-hassle way to determine if it's the motor? I have to wonder if the modules failing in my WK is due to crappy aftermarket stuff or the motor itself.

I replaced the connector/plug, have not had a problem since.

Re: Blowing Resistor packs

The plug on mine appears fine, no signs of overheating, charring or anything.

Re: Blowing Resistor packs

The only way to "test" would be to measure the current draw... Many cheap ammeters cannot even test the fan as it can easily draw 15-25 amps which is above what most DVOM's will be able to handle, furthermore, to measure current without an amp clamp you have to put the meter in series, aka you must basically cut a wire and put one lead on each end of the broken wire to complete the circuit... not suggested at all. If your burning up resistors, I completely agree with Tom, replace the blower motor.

Re: Blowing Resistor packs

Just replaced the motor with a new Mopar one. Didn't improve the situation, but that's probably because the module was shot. Replaced that and now have fan control again. For how long is anyone's guess, but I keep the receipt for it (and it's lifetime warranty) tucked down inside the dash right next to the module.
