Just wondering everyone's opinion on something.

About 3 weeks ago I replaced my blower motor resistor because I lost the medium 2 speed. The new resistor worked great until a couple of days ago when I lost the medium 2 speed setting again.

I used a new resistor from the parts store, the brand was BWD.

Is it sheer coincidence that the second resistor failed just like the first one in only 3 weeks? Could something else be causing it to fail?

Should I opt for the more expensive Mopar resistor this time around?

Thoughts?

maybe could use a new fan

The resistor requires an airflow to cool the hot element. So if either the fan provides insufficient airflow or more likely you have a blockage, then the resistor will fail to prevent a fire. Rodents are known to get into the ducts and build nest. Be sure to check, you'll need to remove the fan.

I've had baby ground squirrels fall out when I removed the fan on my Tundra, just grass on the XJ.

I'll have to pull the blower motor and check into that. Good suggestion.
